I have an Inground pool and I have 7 return jets in my pool. 6 of 7 are working flawlessly with excellent pressure coming out of them with no air bubbles. EXCEPT my 7th jet that is right underneath my skimmer does not work. I have gone on many forums and troubleshooted many times and I still can't get the thing to work Here's what I have tried so far 1. Covered all the other jets eyeballs up and hope the pressure builds to push out anything that is in there (no luck) also when I did do this, the pressure (18psi) remained the same 2. I've drained my pool twice and took off ALL the jet eyeballs and cleaned out the pipe with a wet vac (no luck) 3. I've bought expensive drain cleaner for the pool (no luck) 4. I've checked my D.E filter and replaced with new filters (no luck) 5. Checked all my skimmer baskets and cleaned out the pump motor (no luck) 6. I've changed out all my o-rings (no luck)
I have visually checked for leaks everywhere and the only leak I had found was by my brominator but it isn't a continuous leak and I don't think this would be enough for a single return, to not work? And the way they designed and put in the pool they didn't install separate manifolds for each return so I'm out of the luck with that. So at this point I'm pretty much all out of options unless someone else can point me in the right direction?
