Leak in Return Fitting

by Rob
(Chattanooga, TN)

I just installed a new liner, skimmer box and return jet. The return jet has a very small leak on the outside of the pool. In between the edge of the backing plate and the wall of the pool, there is a very small leak, maybe one very small drop of water every 20-30 seconds. It seems to be soaking in the sand at the bottom of the pool and not even causing a damp spot at the bottom.

Should I be concerned? My solution would be to drain the pool below the jet, disassemble, clean out the jet, apply silicone and install. I'll do it if I need to, but I'm just not sure that it's warranted to dump the water and start over. If it can go for now, I figure that I can do it when I drain the pool slightly for winter storage.


Hi Rob. I’m not one to be overly concerned about every little drip on my own pool, but some people are. Leaks in the skimmer or return fittings on an above ground pool could lead to a rust issue if left unattended. If your return has a butterfly gasket, a one piece gasket that wraps around the pool wall, the water is not coming in direct contact with the inside of the pool. It is only dripping down the outside which is not a concern. Without this type of gasket to protect the wall I would be a little more concerned. This is an area where you would have to use you best judgment.

The other problem with leaky returns and skimmers is the water eroding the ground on the outside of the pool and possibly causing the pool cove to wash out. You have indicated just enough water to keep the sand moist so this is probably not an issue, just something to keep in mind.
