I'm having an impossible time finding a pinhole leak in a residential water supply system. During an air test at 75 psi, the pressure loss is about 5 psi in 30 minutes. Over 14 hours the pressure loss is 30 psi. The lines have been searched numerous times using soap/water to find the leak. No luck.
All the water supply lines have been replaced with new copper and walls are open. Fittings are primarily sweat fit with a limited number of thread fittings. Ultimate working pressure will be about 50 psi. During construction the only water source available is about 30 psi.
Your thoughts?
