Pump too big for pool, read some posts on reducing flow with ball valve

Why don't you just plumb in a by-pass around the filter and heater so you can divert some of the flow? You can use a ball valve to control how much water is diverted. This will allow you to lower the pressure and gpm through the filter for minimum expense while keeping a good supply of water at the pump inlet. Sorry if someone mentioned this already.

We bought our pool package online from a pool place 4 years ago. Just checked the website last night and they are still selling the same pump with filter. From the packaging I think it was a set because everything came in the same box and they sit on the same housing.

It is an above ground pool. The pressure gauge is reading 16psi.

Don't have a heater just a filter and pump. Not sure what you mean by a by-pass. Could you clarify more?

Niclole, from what you have said, you probably have 45-50 feet of head and with an above ground pool pump, they are usually med-low head pumps, I doubt very much you are moving more than the filter can handle. I cannot find the head curve for your pump but I would be surprised if it exceeded 60 GPM.

I think you should verify you definitly have a problem before trying to fix it.
