1HP Waterway E-Series Impeller 310-8020

Spa pump wet end impeller for E-Series Waterway pumps.  This is a 1HP impeller 310-8020.  The original impeller may have this number stamped on the side of it.

Tech Note:

The Waterway center discharge wet end has been discontinued and replaced with the E-Series Center Discharge wet end by the manufacturer.

Please be sure which wet end you have as the parts are not interchangeable.

The easiest way to identify which wet end you have is to count the number of screws on the faceplate.

The old center discharge pump had a 4-screw faceplate and the new E-Series has a 6-screw faceplate.

If you need parts for the old center discharge wet ends, you will need to replace the whole wet end with a new E-Series Center Discharge wet end.
