Product details
The Waterway 3721621-1D is a 4HP Executive series spa pump, two speed, wired for 230 volts, on a 56 frame motor with 2 inch suction and discharge ports.
Why two speed matters on a spa
A spa spends most of its running hours filtering and heating, which needs very little flow. The low speed does that work quietly and cheaply. When the jets are called for, the high speed steps in and delivers the flow the therapy jets were designed around. One pump covers both jobs instead of running flat out all day.
Before you order
Check three things against the pump you are replacing: the supply voltage, the motor frame and the port size. This unit is 230v on a 56 frame with 2 inch ports, and all three have to match for a straight swap. Waterway lists it for spa and hot tub use.
