We are replacing the concrete deck surrounding our community swimming
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
damaging something if he tests at too high a pressure.
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
What material is the piping? I'm not a huge fan of high air pressures
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 don't know about bromine but DC city water tests just about
"perfect" with a 2 bottle test kit ( ~ 7.2 pH and 1.5 ppm Chlorine).
If your pool in within that range it looks like city water to copper
Testing how? If you have chloramine instead of chlorine, it takes several
minutes to develop with OTO colorimetry.
Fill a clean, 5-gallon plastic bucket with your tap water. Is it greenish?
That's chloramine. Compare to distilled water. You'll be amazed.
pH may be the most important one for just about anything pool related.
If the pH is too low it attacks all the parts of the pool (pool
finish, equipment etc) If it is too high the chlorine won't work
right. pH is also the thing that makes your skin and eyes burn. Once
you get the routine down it is fairly easy to keep a pool balanced but
you need to test often and make small changes over time until you
figure out what you need. Trying to fix something too fast will only
start a chemical war that usually results in dumping the pool and
starting over. Just remember this is thousands of gallons of water. It
takes time to see the result of what you dumped in and once you put
something in there you can't get it back out. Use less than the
predicted dose, wait a half day, pump running and add the more if you
My parents pool has copper plumbing (original from 1959 OC SoCal)
still in good shape...as long the water chemistry is properly
maintained copper will last a LONG time.
This installation is approaching 50 years.
Soil conditons will have an effect.
If they had to to any repairs they should have used at least Type L
(medium wall) preferably Type K
On the other hand my house a few blocks away had copper pool plumbing
that is the same vintage but the house had several owners over the
years & pool water chemistry must not have been maintained as well.
No failures but some sections were kinda nasty looking (exterior)
....maybe from storing chems near the filter & attendant plumbing.
