I have an 18x33 above ground pool with a 1 hp Hayward Power-Flo LX pump (1580). The old sand filter was giving trouble last summer and I'd like to get a new one. I was looking at the S244T (300lb - 24") filter but I contacted Hayward and they said that filter would be way too much for my pump and it would not work correctly. I was puzzled by this because my pump has a relatively high GPM rate and there is very short piping between the pool and the filter (maybe 20' of pipe with 4 90-degree elbows). He stated that the biggest filter I could use would be the S180T (150lb- 18"). He said even the S210T (200lb - 21") would be too large for my pump to handle.
Is the S244T too large? Would there be any issues with using an extra large filter? Any help or suggestions would be appreciated. Thanks,
