Hello all! Long time reader first time poster.
I can not locate the leak. I have installed and plumbed a new bathroom complete with tub, shower and double vanities with sinks.
I have all the water lines installed with PEX and copper crimp rings and attempted to do a pressure test with air. I have installed a 120 psi pressure gauge and a Schrader valve to charge the system. I have charged the system to 50 psi numerous times finding a few leaks. The leaks have always been at the threaded fittings that have Teflon tape. I took them apart, cleaned off all the tape and reinstalled using blue monster pipe thread sealer. In every case this has fixed that particular leak. I have also been testing all the joints with Oatey leak detector fluid. I have tested every joint, I have tested every fitting and I still have a leak somewhere because it starts to lose pressure immediately.
After going thru the system probably 3 times completely testing every fitting and every joint and I cannot locate the leak!!
Someone out here please help with any ideas you might have. I have also heard talk about testing with dye and a black light. Anyone have any experience with this method with water lines. Is it safe?
