/diy/ - Do It Yourself

So, after the lead was removed and the interior of the pipe was cleaned, I installed the mechanical plug. I've been running water for around 15 minutes to test it and am pleased to say I have no leaks.

I really appreciate all of the advice everyone has given me. I genuinely couldn't have knocked it out without you guys.

I think this is a good enough temporary fix for now. I will consider either having a donut installed or even replacing the fitting entirely. As you can see from the attached picture, I have good terminal cleanout points and it's not leaking anymore so I feel like this has been a success. Thanks again everyone!
