/diy/ - Do It Yourself

Had a plumber install a new hot water system. Go outside to check on it and water is pouring out of the pressure relief valve. I send the plumber a message and he says "You didn't touch it did you!?" So apparently it is my fault because "I pulled it so hard it now won't seal" which is total bullshit, I pulled it just as hard as my old one and never had any problems, they are supposed to be pulled to see if they are working correctly so pressure won't build in the tank and the way the tap is designed looks like it is supposed to be pulled to full capacity.
