Waterway Viper 4.0HP hot tub pump. The Viper is a high volume pump that has almost double the gallon per minute flow rate compared to the same size Waterway executive 56 as well the Viper is the only Waterway pump that has 2-1/2" intake and discharge.

    this part # 672-4350 is sold separately here

The Waterway Viper series spa pump is not widely used in average size hot tubs. The Viper series pump has a very high flow rate of around 400 Gallons per minute which is almost double that of the same size Waterway Executive 56 Frame pump that has a 2" discharge (Measures 3"). When replacing your spa pump always replace it with the same size pump or as close to the size of the old pump without going to a larger size. If a pump is installed that has a higher flow rate and draws more amps at high speed than your old pump did, it will over load the electrical system to the hot tub and cause the pump to work much harder as the hot tubs plumbing system would not have been designed for eventually overheating the larger pump causing it to shut down.

Manufacturers 1 year limited warranty.
