Impeller, Waterway E-Series, 0.5 Horsepower 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.
