Product details

The Waterway 310-3300 is the high flow diffuser for SVL56 pool pumps. It is the genuine Waterway part.

What the diffuser does

Water leaves an impeller fast and turbulent. The diffuser sits over the impeller and organizes that discharge into the volute so the pump converts speed into pressure. When the diffuser cracks, wears at the sealing face or has its vanes damaged, the pump keeps running and sounding normal while flow and pressure quietly drop.

High flow, specifically

This is the high flow version, not the standard part. Compare against what you remove before ordering. It is a wet end component, so the repair means opening the pump housing rather than touching the motor.

Questions and answers

What people ask about this product, answered by our pool techs.

Which pump does this fit?
It is listed as the high flow diffuser for the Waterway SVL56.
Is a high flow diffuser the same as a standard one?
No. The high flow part is a different component, so match it to what came out of the pump.
What does the diffuser do?
It sits over the impeller and directs the water leaving it into the pump volute. Without it, or with a broken one, the pump loses the pressure and flow it should deliver.
Do I have to pull the motor to change it?
No. The diffuser is in the wet end, reached by opening the pump housing.
