My single speed pump was getting really noisy so I decided to get a variable speed pump. My electric rates are pretty low but I decided on the VS pump because I wanted something quiet. When I called the PB and made the appt. for the install they told me that a 1hp pump was the largest I could have with my 300lb sand filter. The pump was installed today and I see it is a 1.5hp pump. I called the pool builder and asked if it was too big for my filter and they said it should be fine since the highest speed allowed on the pump is 3000rpm.
Is he telling me the truth or will the pump cause a problem with the filter?
