A high head impeller develops more pressure against resistance, which is what a system with long pipe runs, a heater, or heavy filtration actually needs. Fitting the wrong profile leaves you with a pump that moves water freely on the bench and disappoints on the pool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMatch the rating\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eImpellers are matched to motor horsepower. This one is the 5 HP part. Fitting a different rating changes the flow curve and can load the motor in a way it was not designed for, so read the rating off the old impeller or the pump label rather than going by diameter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eFlow that never fully returns after the pump basket, the filter and the suction lines have been checked points at the impeller.
