I’ve got a in floor cleaner system that serves as my pool return. The manifold where the outlet from the filter attaches then distributes the water to 4 pvc pipes that go into the ground and attach to the in floor returns, has a small leak. It’s small enough that it stays damp there but doesn’t spew out water. This system is over 30 years old so parts are hard to come by. What would be a good way to fix this leak? Ive thought about pool putty as I already have some but didn’t know if the constant pressure might effect it. Any ideas? Thank you.
