Found the busted waterline against the wall in the crawlspace I was able to cut out bad section and replace with pex. I verified everything was like free and put the insulation pack up against the wall. Customer had a leaky flapper on her bathroom toilet I was not able to stop it from leaking and did not have any flappers that I was aware of on the truck so I told her to go to the hardware store to grab a 2 inch flapper and be sure that there is about a half inch of play in the handle when it’s installed.
