1.5hp pump with 1.5'' pipe?

[CarlD]

If water is getting to your filter but not the pump, then something is backwards! Water runs from the drain/skimmer to the pump's skimmer basket, then from the pump to the filter, via the multiport. It sounds like you have the drain water going to the filter first, then to the pump.

My point? I cannot see how it's possible for the filter to be filling but water not going to the pump. Can you post pics and indicate drain/skimmer versus return lines?

The pump was sucking water, but it wouldn't fill up the basket to the lid

Where's the water going?

What is the filter PSI?

If it is low, then there is probably a blockage in the suction line somewhere.

If it is high, then the return side might be blocked somewhere and could be the filter.

Either situation can lower flow rates such that the pump cannot expel the air in the pump basket. However, a suction side blockage will also tend to draw in air from the pump basket lid and other places.

Does the filter have a recirculate position? Bypass the filter to see if the pump primes.
