Hi what would cause a CSV125 to start leaking water if there is a power outage and the pressure tank goes empty ??
there was a power outtage and the pressure tank ran out of water and I found water coming from the CSV125,
what would cause this to happen??
Once the pump starts back working the CSV stops leaking water...
-
The CSV125 uses an o-ring seal. It takes pressure to push the o-ring into the crack and stop the leak. Usually doesn't leak when the power is off unless there is backflow causing a vacuum in the CSV.

Can the seal be replace ?? If yes what size is it ???
-
If it continues to leak the o-ring is not the only problem. The tube that slides through the o-ring is either scratched with sand or slimed over with something like iron bacteria. If the tube is scratched a new o-ring won't help. If it last less than a year we will warranty it even if it is sand or something, but we would prefer you use that credit towards a CSV1A that can handle debris without any problem.
