I have an approximately 12,000 gallon fiberglass pool. It is about 5
years old and is cleaned by a "predator 175" cartridge filter made by
american products. This is the problem...when sweeping the pool and
within seconds if the pool is dirty it will start spraying
cloudy/water back into the pool. The filters are not dirty and in
fact they have been replaced several times with no help. Is this a
defective filter and is this normal for cartridge filters? Thanks for
any advice or help!
