We ordered a lake effect above ground pool and an rx clear radiant sand filter from pool supplies.com. About a month into our second season the valve on the top of the filter starting leaking, water would run out of the waste port while using the recirculate mode. On top of being incapable of helping me identify the gasket inside the multiport valve, they also refused to cover the valve under warranty because it is a mechanical item. Poolsupplies.com is a great place to buy cheap junk at low prices but don't expect any help down the road.
