We have had problem after problem with this pool, we just want to enjoy it! The latest thing is the spider valve/gasket for our Vari-flo control valve was seated improperly. This was fixed but then 2 days later we backwashed after vacuuming. Now whenever the filter is on water just shoots out from the lid of the valve where it meets the lower chamber. All 6 screws are fastened tightly, spider valve was even replaced. Help!! Let me know if you need more info.
