We are replacing the concrete deck surrounding our community swimming
pool. A
contractor we hired to replace the skimmers wants to do a pressure
test on the
plumbing that recirculates the water through the pool. It sounds like
a good idea
to find any leaks while the lines are accessible, but I'm a little
concerned about
damaging something if he tests at too high a pressure.

Any thoughts?

TIA

Ed

He should a leak test with WATER pressurized to slightly above maximum
operating pressure of the system

btw the skimmer lines are under vacuum....they suck, they're upstream
of the pump

Pressurizing with air can miss small leaks but its better than no test
at all.

What material is the piping? I'm not a huge fan of high air pressures
in PVC.

cheers
Bob

Thanks, Bob. The lines are copper. They look to be in good shape,
i.e., inside is clean and not pitted.
I was glad to see that because the guy tried to sell us on ripping it
all out, saying that the chemistry of
pool water can leach out copper, so the expected life was 25-30 years.

I'm surprised they are copper. My hot tub chemistry is real hard
on the little bit of copper in it.

Bob F-

If the water chem is correct copper should hold up well
