After cleaning out the cartridge for my Hayward X-Stream (again) the last time, I noticed that the water still looked very dirty every time after I vacuumed. Putting a nylon over the return showed me that junk was bypassing the filter cartridge and getting blown back into the pool. Opening the filter housing and looking at the cartridge / housing proved that the circle the cartridge sits on had somehow gotten slightly warped, just enough so the cartridge doesn't sit snugly and allows some debris to bypass the cartridge. I hosed the cartridge down, put the filter back together, and then when I turned it on I noticed a leak between the top and bottom parts of the filter housing. I did put the ring on snugly. So it looks pretty evident I need a new filter - even though my X-Stream (and pool) is only 3 years old. I've been wanting a sand filter since last year, however, as my friends who have them all love them. I have questions though:
1. The pump that came with my filter is a Hayward Power-Flo matrix (1 hp.) It is still a very good pump. Would I still be able to use it with a sand filter?
2. The pump and filter is on one of those black equipment pad things. Would I be able to use it for a sand filter? Or would I be able to find one that I can use with that pump and a sand filter?
3. The only plumbing I have is a hose from the pool to the pump, a hose from the filter to the pool, a 3 way valve in case I ever needed to bypass the filter but use the pump, and 2 simple valves so I could isolate the filter to drain. Oh, and I also have a backwash hose for when I drain the filter. Is there any other plumbing I would need?
