Thanks for the response. Oddly enough I don't mind drain cleaning at all(except for the occasional one that is a real PITA), but I have quite a bit of experience doing it. I also have been getting decent at figuring shit out on my own, but this one was a real head scratcher. It's an old ass house with several addons since then with a jumbled spaghetti mess of water lines with no manifolds that has been a real struggle to even begin to untangle. It started as a leak detection. I located the leak and repaired, now got called back as there is another leak I did not find because my dumbass didn't do a second static test. I spent pretty much the whole day working for free since it was a call back. Still didn't find the leak. Leaning towards a whole repipe of either the hot or cold side after we add an isolation valve on the hot side and figure out which side is leaking. I've done plenty of repipes Problem is that I don't know how the hell I'm going to repipe because what little attic space there is is inaccessible due to HVAC. The more I type it out the more I realize it probably won't be as bad as I think. I'll figure it out. It was just a really rough day considering I got paid next to nothing for 12 hours. Not to mention I accidentally broke the customer's mirror right as I was about to leave.
