  • Waterway OEM part # 3420610-1A
  • 2" intake and 2" discharge, (3" actual outside diameter on threads)

    When replacing a hot tub pump it is recommended to replace the union O-ring as they can develop flat edges from being compressed over the years and when a new pump is installed without replacing the O-ring the union can leak and if over tightened will crack.
  • Pump cord and unions sold separately.

The PF- model number from your old pump should not be used as a reference for selecting a new replacement pump as Waterway has produced up to 4 known variations of pumps with the same model number which are different enough that they are not interchangeable. Always select a replacement pump with the same part number as the Waterway part number on the label on your old pump.


Good to know:
This is one of the smallest hot tub pumps in the Waterway executive 48 series of pumps with side discharge. Operating at 115 Volts its commonly found in smaller spas that are plug & play type. When selecting a replacement pump for your hot tub always compare the AMPS from your old pump to the new pump to ensure they are similar and not higher, especially the high speed AMP draw, the high speed AMP draw of the new pump should new exceed that of the old pump.

Determine the pump plumbing size by measuring the outside diameter of the wet end male threads. Plumbing sizes for hot tubs are nominal, and not actual outside diameter (O.D.) of the the threaded intake or discharge. Once you have removed the pump, use a tape measure to check your old pump thread size and compare to the sizes below.
Waterway Pump Intake Size
If your pump thread O.D. is (approx.) 2 3/8",  Then you'll need a pump with union size 1 1/2".
If your pump thread O.D. is (approx.) 3.0",     Then you'll need a Pump with union size 2.0".
If your pump thread O.D. is (approx.) 3 5/8",  Then you'll need a Pump with union size 2 1/2".

    Was happy to find this dealer in Canada had this pump as it's not available at a lot of places. Price was good, shipping was quick to New Brunswick.
