Important Product Note:
- Seal O-Ring for 315-1260 Volute Required.
Waterway Executive 48 and 56 pumps from around mid 2017 and newer have an upgraded volute which has an o-ring around the seal cup in the volute. Wet ends that have the o-ring around the seal can be identified by the part number 315-1260 W/O on the back of the volute which is visible if looking at the back of the wet end.
- Seal O-ring for 315-1220 Volute Not Required.
Waterway Executive 48 and 56 pumps from around mid 2017 and older have the standard volute which does not have and o-ring around the seal cup in the volute. Wet ends that do not have the o-ring around the seal can be identified by the part number 315-1220 on the back of the volute which is visible if looking at the back of the wet end. Do not use the o-ring on 315-1220 volutes as it will prevent the seal cup from seating properly and may cause damage.
- Fits Waterway Executive 56 series pump models PF-45-2N22C and PF-45-2N22M 2010 and newer only with first 7 digits of serial numbers starting from PF10277... and up, will not fit pumps with lower serial numbers. Pumps with lower serial numbers or old style serial numbers that start with PF2--, PF3--, PF4-- etc. would need a complete replacement wet end as these parts may not fit. Will not fit any Waterway EX2 series pumps.
Replacing the bearings on the hot tub pump motor requires special tools to remove the bearings from the motor shaft as the bearings are pressure fitted (Pressed on the shaft). Attempting to replace the bearings without the proper tools could result is permanent damage to the new parts and motor / pump.
