"Return to pool" Hose still falls of pool "hose adapter". New hose still same problem. Pool Repair man did get it to stay on, but says it should be rebuilt at end of season. the adapter connects directly to a chlorinator and was securely glued into place. Was told the chlorine chemical wears down the adapter so it now slides off. Any suggestions on how to get a secure tight fit of hose to adapter. Especially if it happens again. I don't care if I have to glue the tube. Just need something to get by if it reoccurs during the pool year?
