I'd thought of temp change - my assumption is that cooling would most affect pressure local to the tank and any sagging would be equally visible with the inline valve closed. If this is faulty logic, would it be enough to explain a 15 PSI drop? Note it continues to drop over time rather than...

Hi Eric, I do. There are two nodes that I have been controlling as part of the debug - see nodes A and B in the previous schematic. With (A) closed, the tank including first valve holds pressure with no leaks. With (A) open and (B) closed I saw some leaking and fixed a few spots - I am retesting...

Hi all, I've just installed a fixed copper air run for my home workshop and am trying to debug the cause of losing pressure over time. Attached is a schematic and here are a few additional specs: * Total network is 200ft 3/4" copper including 4 drip legs and a handmade aftercooler * Drip legs...
