I purchased a 1hp Hayward Power-Flo LX Series for my 22'x4' AGP last summer. I thought our current pump setup (2 intex pumps running side by side) was toast, but it turned out to be debris trapped in the intake of the first pump. So the new pump was never installed. This summer I decided to install it and sell my other pumps as one went with a small intex sand filter and a friend wanted it. I am using an old 200lb sand filter my dad had that is rated for 44 GPM max and my pump shows 60 GPM, I never really thought this would be a problem. But I am now having issues with my pump blowing fine sand/dirty water through my filter, it isn't the filter sand it is fine sand from the pool. If I vacuum a spot that is really dirty I can see it come right out my return. Is there anything I can do besides buy a new smaller pump or larger sand filter to resolve my problem.
