Waterway 2hp 2 speed pump for smaller hot tubs and spas that require a 230 volt pump. Waterway spa pumps are built for performance and reliability. 

Pump details:

  • 2.0HP Waterway Executive 48 Spa Pump, 2 Speed   
  • Waterway OEM part # 3420820-1A, 
  • 2.0" intake and 2.0" discharge, (Measures 3" outside to outside)
  • 220-240volt, 
  • 10.5 Amps high speed (3450 RPM) 
  • 2.8 Amps low speed (1725 RPM). 
  • New cord and unions not included, sold separately.
  • We Include,2 union O-rings automatically added to cart at checkout.
    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.

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.


Orientation of wet end.
Pump wet end can be oriented in 90 Degree increments, up, left or right. Pump will ship with discharge directed up. To change the discharge orientation, loosen the pump's four through bolts from the back of the motor and pull them back enough to disengage. Then rotate the wet end to the desired position, realign and re-tighten the bolts.  

Pump Intake Size
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.
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".
Please note!
Some brands of hot tub spa pumps have non-standard threads and use fitting sizes with different dimensions. These brands are: Hayward, Jacuzzi and sta-rite.
Manufacturers 1 year limited warranty.

    Not sure how they can offer such good service and great prices with fast shipping. None of my local dealer had the pump in stock but could order it for me it would only take 1 - 2 weeks. Pool depot had my pump to me in less than 3 days. Keep up the good service as I will be back for more parts.
