The 4 HP Waterway Executive 56 # 3721621-1D is a durable, high-performance pump that delivers reliable water flow efficiently. Always select a replacement pump with the same part number as the Waterway part number.
Pump arrive fast, well pack. Was a perfect match.
Replaced the pump in my hot tub, was easy to swap. Friendly and helpful staff along with great prices. Highly recommended.
The pump works great but it does not come with seals or fittings to fit the drain plugs for the air hoses. The threads are none standard and tough to seal.
