CPVC master race checking in

We've had pex in our house for like 20 years and no smell problems at all and no hint of impending failure. Not the slightest weep.
>UV sensitive
not much of a revelation, pex packaging says this all the time and to not leave it exposed to the sun. Good thing pex is used indoors eh?
>Rodents are known to chew on PEX pipe, known to aid in the development of some bacteria-forming biofilms when used with non-chlorinated water systems
Silly. A rodent chewing on the outside of a pex pipe isn't going to cause bacteria problems inside. And if the rodent bites through, it'll cause a leak, and the plumbing system will have to be emptied anyway, and the section replaced.

>>1936974
Plastic pipes don't work with hot water in general.
So, UPVC and HDPE are good plastic pipes for cold city mains.
At home, you want copper or galvanized or stainless. Because leak at home is way more expensive than leak somewhere in the sidewalk.

>>1937023
>shilling galvanized and super expesive stainless
Do you even plumb, you retard?

>>1936974
>Rodents are known to chew on PEX pipe, known to aid in the development of some bacteria-forming biofilms when used with non-chlorinated water systems, extremely sensitive to UV light, PEX can be dam
If rodents chew on your pex enough to create surface area for bacteria and mold, and that somehow gets into your water, you have a huge leak. Unless you mean the rare swimming cold supply rat. You're a fucking moron.

>>1937023
>stainless
>Galv
You're smoking crack

>>1937035
In some areas copper doesn't last, but galvanized steel lasts.
Stainless is good, but rare and thus expensive. It is like copper without drawbacks.

>>1937038
>Galvanized steel lasts
Depends what part of the country you live in, and I’ve yet to see a home or commercial building done in stainless. Do you know what you’re talking about?

>>1937044
Thin-walled stainless tube with crimp fittings.
They are super rare tho.

>>1937023
>Plastic pipes don't work with hot water in general.
The hell are you talking about, pex is everywhere and handles hot water just fine

>>1937051
I am going to put this everywhere I work on in my home. This is one of those pains in the ass that make you ask what the last guy was thinking. I shall be that guy.

>>1937142
God bless you sir

>not having copper pipes
how do you people survive

Did anyone actually know from where PEX pipes came from ? Drum Roll, Brrrrrrrrrrrrrr ............................ Underfloor Heating! They were never ever designed to be used as a replacement for copper or galvanized pipes but they were approved because its super cheap and its quick to install. The issue is that its a 3rd country world material that should never been used for anything except underfloor heating but its like they saying goes, you get what you paid for. I can't wait for the ads in tv saying "Have you or any of you loved ones been exposed to PEX pipes, you may be eilgible for compensation"

>>1937051
Those are called Propress fittings. I don’t think I’d trust that rubber o-ring buried in my walls. You’re never going to see that in residential shit.

>>1937142
>not using welded stainless

>>1936974
I'm a copper and CPVC man myself with no real experience with PEX, but

>Rodents are known to chew on PEX pipe, known to aid in the development of some bacteria-forming biofilms when used with non-chlorinated water systems

has at least 3 things wrong with it. First, rodents chewing on the outside of the pipe can't induce contamination inside unless they breach the pipe, in which case you have a big leak. Second, biofilms don't form bacteria, it's bacteria (and fungi) that form biofilms. Third, any submerged substrate with no anti-microbial properties and no chlorination can host biofilm growth - it's not specific to PEX.

you are clearly a fanatic retard with an agenta. I won't go into detail but simply put 80-90% of new pipework in Europe for the past 10-15 years has been PEX.
There are very good reasons for this, reasons you obviously choose to ignore. So fuck off.

>>1937142
Based.
>>1937201
> You’re never going to see that in residential shit.
I saw that shit in residential, but this is rare and I don't get why?
>>1937217
You're little motherfucker...
>>1937078
PEX becomes brittle as fuck on hot water. Like CPVC, but even CPVC lasts probably longer.
>>1937220
It doesn't last long. Copper lasts. Galvanized lasts. Lead lasts. PP-R sorta lasts, if we're speaking about Europe. PE-X and PE-RX fucking fail for no reason, unless you have real low pressure and fucking distillated water instead of potable with chlorine and minerals.
I had PEX failure in 7 fucking years. Like to the point you could grab the pipe and it would be like... pipe of ice.

>>1937220
Agenda? Just wait when people get seriously sick! Europe isn't Europe anymore, they need a lot of cheap houses to be build to solve the immigration problem same as USA. There are already lawsuits being filled all over USA against PEX pipe companies, but of course you won't hear it on tv yet

>>1937181
$40 bucks every 5 years. or $560 fo 70 years.
$350 bucks every 70 years.
huh

>>1937051
Why not swagelok?

>>1937246
Wrong, I've owned the same auto and truck engines and used them for decades. The gaiter seals in auto HVAC systems (whose working fluid is far harder to retain than water) easily last twenty years or more under far more demanding conditions than mere household plumbing. Their parent alloy parts or the pump normally fail first.. Internal seals often last much longer in engines and transmissions. Diesel engines in commercial vehicle can rack up a million miles before overhaul with 600K miles being routine. The engine frequently outlasts the truck.

>>1937319
Those last decades on aircraft engine and hydraulic systems including fighters which pull 9 Gs. They are not normally time-replacement items. They're too expensive for home use unless you're rich but they'd certainly do the job.

>>1937319
I don't know, this is what I've seen and I was amazed and confused, because pipe itself isn't that expensive compared to copper.
Hmm... Why not flares?
>>1937329
They are overkill I think. But flares seem like a good alternative.
>>1937324
This rubber might be very different from rubber certified to be with contact with water.

>>1937051
fuckign hell americans will do literally ANYTHING to avoid soldering pipes huh.
it's not even that difficult ffs.

>>1937341
You can't really solder stainless. This is the problem.
Also this is not american thing.

>>1937344
You cab braze stainless, and tapered thread joints work fine too. The problem is cost since stainless is expensive. I use plenty of NPT threaded small pipe (cheaper than buying brass locally thanks to Chinese serfs) on my projects but larger sizes aren't readily available. There's no need for soldered or brazed joints in stainless except cost and convenience vs. threading pipe sections. (Stainless is rough on tooling.)

>>1937360
>You cab braze stainless
Yes, maybe.
>, and tapered thread joints work fine too.
Not really, at least not on thin-walled tubing.
>The problem is cost since stainless is expensive.
Not really. Stainless thin walled (15mm x1mm for ex, which is plenty for water) costs about the same as copper. Yeah, copper is easy to solder, but stainless should outlast copper in theory. But with viega crimps it is easy probably. Idk, never worked with it, I just have seen it installed, and at first I though it was chrome/nickel plated copper.

One thing for sure. PEX is a disaster. It doesn't last, can't be recycled... Copper and stainless and even galvanized can be recycled. Even PVC I think.

There was a very good article I found a long time ago by a materials scientist who specialized in plastics. He was running experiments with all forms of plastic pipes and the evidence he presented (it was all legit papers) was pointing to the fact that the pipes will always leech micro particles of plastic into the water. It's just how the material degrades over time. Then he was presented all the different research involving micro plastics and their detrimental health effects. I would have really liked to link the article to you guys but I cannot find it anymore and I lost the bookmark. Maybe memory holed but who knows.

Of course there is also research that warms of the various chemicals used to manufacture the plastics themselves leeching into the water, which another study (also can't find it, really sorry guys) says that while the amount of these chemicals leeching into the water drops after 30 days, it never stops, and the chemistry of most treated tap water will continue to react with the plastic pipes and form toxic chemicals.
https://www.fondriest.com/news/not-drop-drink-plastic-pipes-leaching-chemicals-drinking-water.htm
That link alludes to the other study I can't find, Ill try and find it again but no promises.

In short, PEX is bad for your long term health, don't use it for any water that you drink or bathe with. You should filter your incoming water, and use quality copper pipes.

>>1937329
I didn't actually realize they were expensive. I work in industrial construction, so we just have literal shipping containers full of them.

tdlr?
Which plastic is the best?

>>1937391
that sounds like it could be interesting. what do you do there?

Since there seem to be people who know stuff in here, has anyone ever plumbed flexible copper pipe? I've seen it done once in a clients home, plumbed much like PEX, with as few sharp bends and fittings as possible. Home owner had gotten some industrial piping guy to do it. The install was beautiful, I had a bit of chub DESU.

>>1937397
I've installed mini-split, and it had annealed copper lineset.
Also I've seen some old-school plumbers heating hard copper pipe red hot, cooling it rapidly with rag, and then bending like if it was annealed.

>>1937382
>In short, PEX is bad for your long term health, don't use it for any water that you drink or bathe with. You should filter your incoming water, and use quality copper pipes.

So is there any difference between one copper pipe and another one ? It seems like there is only few brands that make them. Whats a good company?

>>1937414
There is. Chinese copper is bad. Chilean copper is good. Mexican copper is good. Idk about US, or EU copper, but I guess they are good too.

I only used pex once, never again. It's nowhere near as easy to work with as they say, you got to spend $110 for a crimper, you got to strap the shit down way more than copper pipe because it flexes and moves all over the place with water hammer. The fittings and crimps are expensive, unless you get the cheap plastic ones, then it just seems like you're playing with fire.

All in all, all things considered, it seems like copper is only slightly more expensive and about as much work to install it, plus it lasts a hell of a lot longer, is way more durable, and your water doesn't taste like a ghetto swimming pool afterwards.

what about lead pipes?

>>1937414
The pipes have different ratings for thin or thick walls.

>>1937428
Don't leach shit if you don't move and have proper water.

>>1937324
A good water distribution pipe needs to last a lot longer than 20 years.

>>1937382
What about PVC and CPVC?

>>1937397
I have plumbed on jobs with soft copper tubing yes, what would you like to knowv

>>1936974
Don't care.

Still running pex.

>>1937525
For underground line (well to the house) can i use soft copper 1" type K or i need to have hard copper pipes ?

>>1937555
>still running pex

>>1937571
Yes using 1” soft copper is perfectly fine underground, that’s how most home with copper under the slab are built with soft copper under the concrete and hard copper above. If you’re stubbing the pipes through any concrete though just make sure you wrap the pipe with some kind of isolation tape or a PVC sleeve over the copper so no concrete comes into contact with it.

>>1937264

PEX lasts way longer than 5 years, but even with your fucked up wrong math PEX comes out cheaper when you factor in time value of money. Cry more n00b

>>1937696
Um no. 5 years is about right for PEX.

>>1937696
>cry more n00b

That's a nice womanly figure she's got.

They even have pex hor radiant heating up to around 200° F.

fukken retards, all of you.

>>1937395
I repair the overhead pipes in the facility, water on valuable metals is a no-no. Weird thing is it's always in empty storage..

>>1937788
Recycled copper is a major issue. we have replaced piping in copper laid houses that were 4-6 years old.
Old copper did not have flakes of steel or iron in them, that I think creates a type of electrolysis with flowing water (not a scientist) and creates pinholes in the sides of pipes fucking everywhere.
I also think ground wires attached coupled with this cause major leaks since we have had a few cases of major electrical problems and then water creeping up from the foundation directly after.

>>1936974
Honestly not sure why more people don't still use copper. They're cheap, safe, corrosion resistant, lightweight, and last for fucking ever, not to mention no toxic cocktail or petroleum emissions used in its manufacture like plastic. Are people really too dumb or lazy to learn how to do a bit of soldering these days?

>>1937428
unironically the best material for plumbing (hence the name)
retvrn to tradition

>>1937640
Thanks for the help.

There's 3 different types of PEX
Class C
Class B
Class A

Class C is the old shit, if you see "Made in China" it's Class C and you avoid that shit.

Class B is what you'll find in your BIGBOX home store and you use with SS crimp rings.

Class A is the good stuff, also known as Uponor or Wirsbo Pex, it has a different chemical makeup it's completely inert and is installed with special expander tools and fittings unique for just that grade of Pex.

I am a small time home builder and remodeler, and all I use is Class A Uponor expanding pex.

Using copper in any home building or remodel job is a guarantee that methheads (like Hunter Biden) will break in to steal the pipes.

>>1938063
In other words, get your pex from an actual plumbing supply house like Ferguson’s.

>>1937790
SEETHE

>>1938063
Stop living in shithole where copper gets stolen.
>>1937930
This is what you get for using chinese copper pipes.
>>1937934
Stainless man, fuck copper.
I really don't know why stainless isn't used more often.

>>1938076
>I really don't know why stainless isn't used more often.
Cost and unknown long term durability with propess fittings

>>1938076
>Stop living in shithole where copper gets stolen.
Copper theft is national, it does not matter if you're in the urban jungle f the cities or whitest of white red suburban America, a construction site with any copper pipe will draw out the methheads like shit draws flies.

>>1938076
>I really don't know why stainless isn't used more often.

Holy Fuck are you a moron.
Cost is key in construction, I can get a house plumbed in Uponor Pex (material) for under $1,000 copper in material would be rought $2,500 then stainless? Holy Fuck, there'd probably be like $6,000 for no added benefit.

>>1938079
Propress will last. Not as good as solder, but on copper it lasts.
But there are other types of fittings... Flares for example. Maybe braziling would be viable.
>>1938087
>I can get a house plumbed in Uponor Pex (material) for under $1,000
This is not plumbing. This is temproary mobile house tier hose.
>copper in material would be rought $2,500
If you need $2500 of copper, you live in big enough house to afford spending $2500 on something that lasts
>probably be like $6,000 for no added benefit.
Pipe itself is a bit cheaper than copper.

Fuck copper, I want iron and nickel in my water.

>>1936974
>Don't install pex here are a few niche strawmans >Plastic pipes bad use copper!

Meanwhile your municipality piping is unmaintained shitty plastic or old corroded steel piping both piping are filled with water clams and fucking up shit that stick to the walls of the piping.

>>1938116
Steel rust is good for you.
PVC-u is meh.

>>1938116
utility lines are
larger diameter (less contact area/volume)
less stagnant (more customers means less time in contact)
also pretty stupid argument "i've already drank a little bit of poison, might as well drink more of it"

>>1937742
Not as womanly as she would be after I'm through with her

>>1938152
u a lil bitch

>>1938063
It does not matter what class because its still plastic and less toxic but it still toxic. You don't have to worry about people breaking in because you insure everything thats on the site and take pictures after install. I assume people aren't that retarded and leave copper pipes on a site just sitting there because thats your own fault, do you leave money on your property just sitting there too ?

>>1938076
Our copperpipes in this region are made in Louisiana no china you dope. I think you want copper to be the standard so you can charge more for the extra labor time or you don't do repair.

>>1938279
>You don't have to worry about people breaking in because you insure everything thats on the site

Newsflash, the kind of insurance that is available for construction does NOT cover theft or vandalism.
Basically construction site insurance only covers fire or liability.

>>1937341
Just stop. A while back I had a euro brag about how all they used was stainless, and stupid Americans were still soldering copper or using PEX. Fucking euros just want to make up any excuse to bitch about America.

>>1937370
Stainless should outlast copper, but will a press cut o ring outlast a solder joint?

>>1938299
Real question is where do they get raw material? Do they recycle themselves, or they get it from elsewhere?
>. I think you want copper to be the standard
Yes. So I buy a fucking house and don't think about plumbing for, idk 20-50 years.
In my country they were trying to fall for memes:
PP-R: leaks in 10 years.
CPVC: banned due to being so fucking brittle
PEX: not used widely yet, but it is already failing... Rehau btw.
>so you can charge more for the extra labor time or you don't do repair
Meh, I'm not a plumber. But I know how to solder, and how to thread iron pipes, braze and such.
You see, usually when plastic fails, people just call plumber to remove all fucking plastic and install copper, galv, whatever, but not this shit again.
When metal fails - usually depends. If it is too old and rusty, or walls are super thin - people replace shit with plastic, because it is cheap, and they are going to flip a house anyway.

All PEX at Home Depot is from China. Don't let lazy niggers pipe your cardboard house with Plastic water pipe.

>>1938501
Depends on water.
I think flares are better way to connect stainless tubing.
>>1938499
And euros invented fucking PEX.
10/10.
Also no, euros don't use stainless.
East euros use PERT, PEX, PP-R or galvanized, because in east europe copper gets stolen.
In west europe, you have 200 year old lead, copper, galvanized, pex, sometimes PP-R, polybutelene, PERT, etc.

Also euros have one kitchen sink, one bathtub, one toilet one sink, and washing machine.
They don't have 5 bathrooms, utility sinks and such. So they can use shit pipe

>>1938503
HURR DURR I CAN PUT PIPES TOGETHER IM PRACTICALLY A MASTER PLUMBER.
Shut the fuck up homeowner.
Pex has been around since the 70's btw, more lawsuits would have been made like they were for kytec pex. And in my 12 years of plumbing I would have seen leaks on 20+ year old houses that had original pex far more often but I haven't seen but a couple.
Virgin copper was the standard for plumbing pipes but then they laxed regulations around the 80s-90's they started using A/C grade copper (recycle) which they get from foundrys just like everyone else.

>>1938792
>Pex has been around since the 70's btw
Which wasn't used for potable water until, idk 1990-2000.
You see, heating system is different from potable water system.
In some places they don't even allow thin copper pipes for potable water, but allow to use those for heating applications.
I've seen PEX (Rehau) fail in 10 years. Because it is super sensetive to chlorine, and we use fuckton of it here.
>HURR DURR I CAN PUT PIPES TOGETHER IM PRACTICALLY A MASTER PLUMBER.
There is literally nothing to residential plumbing. Including gas.

>>1937934
Copper can corrode through from the inside out.

>>1938806
This is why stainless thin walled rigid tubing is the future.

Please don't be a victim of toxic water and replace your PEX pipes as soon as possible, your health could be at risk. Take your water sample and get it tested as soon as you can.

>>1938802
>There is literally nothing to residential plumbing. Including gas
So could you plumb a house from star to finish and have it pass inspection? I don’t think so.

>>1938849
Depends. Simplier it is, more chances it will pass first time.

>>1938860
>Simplier it is, more chances it will pass first time.
Pretty sure that goes without saying, and could apply to anything.

>>1938802
They started using pex for residential in the 70's but it only started to get popular in the 90's due to cost.
And don't "you see" me you niggerfaggot, there is 3 different thicknesses of copper for plumbing- but that's not at all what I was talking about when I said HVAC grade copper. I didn't mean the thickness of the tubing, I meant the actual material they use to make it. Up to the 90's the only recycled copper TUBING was for HVAC because it doesn't hold water. Now it's all recycled because virgin copper is expensive as fuck.
If chlorine is a problem because your water is that fucking gross put a whole house charcoal filter on ya pansy.
And I seriously doubt you could plumb a house, waterlines are easy. It's the drains and code that are the bitch. Christ on a cross this is like arguing with a fucking fresh engineer with 0 field experience.

>>1939187
>If chlorine is a problem because your water is that fucking gross put a whole house charcoal filter on ya pansy.
>install expensive failure point that wasn't needed with normal pipe material
Okay.
>. Up to the 90's the only recycled copper TUBING was for HVAC because it doesn't hold water.
I don't believe you at all. Copper was always recycled, because mining is hard.
Problem is that some places recycle copper properly. While others (china) - not so much and end up with enormous amount of impurities. Sometimes you can even see difference in color.
Also, how do you know it is copper pipe that is the problem, but not iron rotten mains that shits with iron particles? There were cases where failed water tanks caused pipe to fail due to rust and iron.
> It's the drains and code that are the bitch
It is not hard to follow a code, you know.

>>1939219
t. Guy that thinks he’s a plumbing expert because he has basic knowledge

>>1939231
I dealt enough with copper and chink minislits and fridges to tell that chink copper is shit, and HVAC grade local copper tubing (that follows ASTM B280, not some weird chink ass standard of making paper thin walls out of shit grade copper that will crack on flares and shit with vibation from outdoor unit) is better.

>>1939219
Whole house filters should be on all homes because they are cheap and chorine wrecks the O-rings in fixtures and will filter iron flakes from the water main that you had said causes the "failure of copper" which is horse shit. Just because you have had bad experiences with HVAC copper doesn't mean you know anything about the history of production or the service of plumbing copper you twat.
And yes, code can be hard to follow because it changes from one county to another and the code is dictated by know it all retards like you who in reality know fuck all about the industry.
Next you will tell me expansion tanks make sense off paper and flat venting is wrong.

>>1937919
OY VEY YOU'D BETTER DELETE THIS RIGHT NOW!

>>1938503
>PEX: not used widely yet
perhaps you should look outside your borders to places where pex has been standard in the building code for the last 20 years or so? we dont have any of the issues you mention and we specificly ban hidden copper pipes for pic related reasons.
these guys test and certificate all building materials used here, if they say its safe it is so. period.
honest question, whats your contry op?

>>1939588
forgot link https://en.m.wikipedia.org/wiki/SINTEF

>>1939473
>causes the "failure of copper" which is horse shit
No. In my shithole, commie blocks have old leaky galvanized (and sometimes even fucking black iron) pipe on water. If you use there copper - it will last 10 years at best, even thick K stuff because of rust iron.
Pic related is typical state of water mains in those houses.
>Whole house filters should be on all homes because they are cheap and chorine wrecks the O-rings
For like 50+ years there were no filter and things worked, O-rings lasted long enough not to bother, why do you need one now?

>>1939588
>we specificly ban hidden copper pipes for pic related reasons.
Fucking retards. Plastic pipe would freeze and fail too, because after couple years it would get brittle as fuck.

>>1939599
naw PEX does much better in freezing conditions than copper. trust. i live in canada

>>1937428
Since about 2000 give or take, they are known to be rather unhealthy.

>>1939622
I live in russia, and if your pipe get frozen and you have iron - you're fucked. If you have HDPE - you're fucked. If you have copper - you're fucked because it was stolen. If you have PEX - you're fucked. If you have PP-R - you're fucked.
In all fucked cases you will have a leak and explosion and complete pizdec.

So you better not get pipes frozen.

>>1939624
*2000 years ago

>>1939588
Under the building or outside the copper pipe should be at least 4 feet underground. When you build your house out of 2 x 6 you should have 5.5 inches of insulation and your copper pipe won't freeze, if your house is made out of cinder blocks or brick you should have at least 5 inches of Styrofoam. The only way copper pipe will freeze is if your house has not insulation or bad job at connecting copper pipes, if its done right it will last hundreds of years. One more thing (this is where most people even the plumbers don't have any clue) You need Copper TYPE K for everything, NEVER use M, type L is if your on limited budget and yes PEX pipes are the cheapest and the most unreliable material in the plumbing industry

>>1939685
>freezing pipes
Florida kangs rise up

>>1936974
PEX is somewhat easier to install in new construction. It is a LOT easier to install when replacing old plumbing. You can snake it through spaces just like wiring.

PVC and galv. steel that need replacement typically get PEX. There have been scammers that run around and convince people to replace their copper plumbing in our area with PEX. We don't have corrosion problems with our water. Either health scares or environmental (the little fishies don't like the smell of copper).

>>1939685
>One more thing (this is where most people even the plumbers don't have any clue) You need Copper TYPE K for everything
Never ever had problems with L or M. They don't even sell K in my shithole (not in stock, special order).
L is even certified to use with LPG (joints must be brazed with silver containing solder though, even though historically you were allowed to use 50/50 solder).

It never freezes here tho. And water isn't abrasive

>imagine not using galv steel

>>1939685
you think where you put your pipes in the walls makes any difference at all when its -30 outside, the power goes off and the owners are on a 2 months cruise?

no, you need pex. stop shilling this shit, you dont know more than the entire plumbing business in half the world. i doubt you know anything at all.

Turn off the water off in the ground, drain the line. Simple as.
>no, you need pex.
Any pipe would burst if you don't understand this. Including pex. No reason to use shit pex that might be flexible and shit for first 2 years, after which it becames as rigid as copper, and as brittle as glass.
Idk maybe you have distilled water, but we have fuckton of chlorine and other shit that oxidized any rubber-plastic (except for Teflon) and turns it into brittle mess.

pex pipes = cancer

Nothing I love more than touching a galvanized pipe and starting a leak from the dust being moved on it.

It takes about 50 years to get there.

About to take over a massive 4 building facility with 200+ residents and tons of common space. Lots of PEX in that building. Anything I need to look out for, tools I should have, things I should learn, etc?

>>1940290
You should replace all the PEX with copper. Do the right thing at least once in your life

>>1940290
Obvioulsy have PEX tools.
>>1940437
I've doubts owners will agree to replace all PEX to copper because it is expensive.
Homeowner might do this. Niggers that own flats might do this. Not fucking building management.

>>1937044
what about aluzinc?

>>1937051
this, my whole house water supply is plumbed up in 37 degree flared hydraulic tubing (.120" wall) and JIC fittings and the odd hydraulic hose where I had to make a tricky jog. It's rated to 4500 psi, so I think it will last a while. Most of my DVW is SAE 45 flare with a couple Komatsu 30 degree flares where the part was cheaper.

>>1940881
Aluminium is not safe for water tho.

>>1940915
Magnificent if true.

>>1940438
>I've doubts owners will agree to replace all PEX to copper because it is expensive.

I just don't get it, what do you mean it's expensive? Do you know how much they spend on a kitchen, bathroom, etc. and besides that, if you can't afford to have the house build right, you should not be buying a house at all.

>>1940980
>I just don't get it, what do you mean it's expensive?
First of all, they already have PEX installed. Second, copper itself is expensive.
And most importantly, imagine ripping everything and patching - just expensive.
This is a commie block. Nobody cares, because everyone is renting probably.
> Do you know how much they spend on a kitchen, bathroom, etc. and besides that,
You don't understand. Kitchen and shitter is something you see. Client comes and says "wah", falls for a meme granite countertop and rents this shithole. Pipes - he doesn't think about them, they are something inside walls. He is temporarily here, and he doesn't care about water damage that will happen in case of failure - it is landlord's problem.
> if you can't afford to have the house build right, you should not be buying a house at all.
I wouldn't agree with that. If you can't afford a right built house, fix one that isn't built right.

>>1941078
>This is a commie block. Nobody cares, because everyone is renting probably.

What will happen if a lot of people complain about the quality of the water, what will happen if someone actually gets sick? Believe or not but a lot of people do test their water and if something goes wrong and enough people come forward there will be an investigation. Search for "Flint water crisis" that should never happen to those people.

>>1941099
You're a fucking retard if you think that having PEX in your building is a liability for renters to complain about taste and health issues. If there is a taste difference at all between PEX and the alternatives, it quickly vanishes after installation. As far as health complaints, the material is code and Gov't approved and has passed tons of comprehensive examination and studies. Getting sick after drinking some water that came through PEX? Get real faggot

>>1941099
>What will happen if a lot of people complain about the quality of the water,
Probably nothing, because legally you're allowed to use PEX and building mgt would tell owners to fuck off or pay more moneys.
I've complained a lot of times on rust in my water when I lived in a commie block. Did they swap rotten mains? No! And here you're talking about fully working system.
They will only replace it when it would cause expensive damage.
>what will happen if someone actually gets sick?
I've doubts PEX effects are so noticeable.
Unless you have water that stayed in pipes for too long.

>>1941106
>the material is code and Gov't approved
So was asbestos and lead pant. Wait another 10 years.
>>1941190
>I've complained a lot of times on rust in my water
You need to take a sample to a laboratory and if the water is contaminated with rust you have strong case in the court. Any lawyer would jump really quick to take your case, that's how it is in USA at least.

>You need to take a sample to a laboratory and if the water is contaminated with rust you have strong case in the court. Any lawyer would jump really quick to take your case, that's how it is in USA at least.
Imagine wasting fuckton of money in court for some rust in water.
>So was asbestos and lead pant. Wait another 10 years.
Asbestos were banned without any real reason.
Lead paint - same.

>>1941290

People say that all the time but when they in the hospital dying, they change their mind really quick but then its usually to late.

It still would be cheaper than suing the building management and city.

>>1941313
Most lawyers would take this case for free if you have clear evidence that there is a harm to the community of people. Lawsuits like this can be as much as hundreds of millions of dollars and most lawyers take 33.3% commission after the case is finished. I don't know in what kind of world your living but seriously good luck to you.

We should create a campaign against PEX pipes

That's what the process of annealing is

>>1942179
yes

>>1937709
My PEX pipes fell apart after 7. Had to tear out walls and insulation and it cost WAY fucking more than 40 dollars per foot.

>>1944403
What did you replace it with?

>>1942179
You don't need to quench copper after annealing but it makes it faster to work with with vs. letting cool in air. I've annealed many copper head gaskets as well as pipes. If you've no water handy don't worry about it. You can also anneal copper brake banjo washers for a better seal.

>>1944521
What I've found is that if you let copper cool naturally, it isn't as soft as if you would quench it. But that is feeling, nothing else.
Btw, it is a good idea to anneal flares on mini-splits ACs.

You people are all pathetic The only thinking man's water is a large glass funnel on top of your roof that catches water from a waterfall and channels it into a smaller waterfall in your living room that you base all of your water needs off of.

Fit pieces together with glass solder and put thick protective foam over it.

My roof is leaded and covered with bird shit. Not sure it would be tasty tho.

>>1937397
Any one that does HVAC uses that. I ran my water supply line with that. It is common to use for water supply lines from the street. The OD is different then hard pipe. Hard pipe uses ID and flexible copper uses OD for its size.

>>1937919
/pmg/ was right! Anon, buy silver!

That is how you anneal copper. Cooling rapidly only adds a faster hand working time.

There are copycat brands that are cheaper though, and just as good - at least for non critical use.

Diffuse water for clean water in glass and not metal containers and tubes
