I finished soldering the supply lines for my kitchen, laundry room, and utility sink, and I am running an air test to see if there are any leaks. I figured I'd do an air test rather than just hooking up the water because I might have a better chance of getting a bad joint to take new solder if it hasn't gotten wet. I looped the supply lines and filled it up with 100psi of air. From looking at the pressure gauge, it looks like I've lost around 10psi after an hour. I checked the gauge itself for an easy leak to fix, but no such luck. I haven't checked all of the joints yet, but I had a few questions to make sure I'm doing this right before proceeding.
I'm testing against the closed valves of my washing machine and ice maker supply boxes. Is this correct, or should I open the valves and cap them? These valves all have built in hammer arrestors. Would this affect the results? I soldered my supply lines directly to the washing machine and ice maker boxes. Is it really easy to apply too much heat to these joints to affect the seal of the valves? Thanks for your help.
