Filter Problem???

[Poconos]

With the larger than necessary pump you're just using more electricity than you need however for the cost of a new pump it probably isn't worth it at this time to change. Depends on new pump cost, if you can sell the old one, electric rates, run times. The pressure seems right in range, not too high, so you're not driving the heck out of the filter. Relax, enjoy the 90 deg heat, and send some up my way. I may be in the pool by July at this rate.

I just went out to vacuum again, here's a question regarding the pressure. When I just run the filter, the preasure shows around 17. When I hook up the vacuum, it starts at about 14, then after I sweep a while, it gets up to around 20 before I backwash. I can tell this point because it quits pushing much water out of the return. Should I stop and backwash before it gets to this point, or will it hurt if I continue sweeping at 20 or is there any certain number I need to be aware of to not let it get above?

How high does your pressure gauge go (if the needle were maxed)? I wait until my pressure is up about 10psi before I backwash.
