I'm finally getting around to doing an air pressure test on the PEX waterlines I've installed. I probably should have tied the hot and cold together before running them into the empty hot water tank, but this should work anyway.
Except I'm having a very frustrating time trying to identify why I can't hold the pressure. I've attached the pressure gauge to the exterior faucet for my test.
Almost all the rough-in lines are capped off, except the laundry that has a shut-off for both hot and cold in the box. AND except for two exterior faucets that have anti-siphon valves attached. Could it be that the anti-siphon valves are allowing the pressure to drop?
Thanks for any assistance.
