We're a couple of weeks away from pouring the deck, and I'd like to pressure test the lines. It's been a while(couple of months) since it was first tested and past inspection, and there's been a lot of foot traffic since.
All the plumbing is still set-up for testing, except for the waterfall line which was cut to fit during it's construction, and the auto-fill line was moved to a different source.
If I have to, I could call the PB to have someone come out, but I'd like to start back filling this weekend instead of waiting a couple of days for them to show.
I noticed that above the pressure gauge there's a spigot, and at the gauge, there's an air valve. I thought that the test was done with water, but why would there be an air valve? I'm starting to think that the test is done with air instead of water, like the gas lines are tested with air instead of gas.
Could I just cap-off the waterfall line and fill the system with air? How many pounds for how many minutes? Would that cover the auto-fill line as well. The auto-fill source is tapped off of the sprinkler system and that valve is in the closed position(off). After the closed valve is the anti-siphon followed by another valve in the open position(on).
Thanks, John
