The 4.5 HP Waterway Executive 48F #3421821-1A is a durable high performance pump that delivers reliable water flow efficiently and is thermally protected. Always select a replacement pump with the same motor amperage or slightly different. The rating performance is still the same. Waterway model reference PF-45-2N22C4 or PF-45-2N22M4.
I had switch the hi and low speed wires for it to work correctly.
Pump works great and shipped very quickly . My hot tub works now!
I ordered a new pump from Canada Hot Tub. The transaction was easy, shipment was extremely fast and the pump was well packaged.
I ordered as per talking to someone and by the description it was said to order this unit and it fit like a glove....
