Waterway are the worlds most common hot tub pump brand, we have the full range of replacement Waterway wet ends on the shelf for all their hot tub pumps. Waterway wet ends are available in 48 frame and 56 frame sizes and a range of various horsepowers.

The best way to work out which replacement you need is a follows,

Firstly work out whether you need a 48 frame or 56 frame, you can do this by removing your old wet end a measuring diagonally the centres of the four motor mounting studs. The centre to centre measurements are 48 frame - 130mm and 56 frame - 147mm.

Secondly, measure the inlet and outlet, Waterway wet ends come in four combinations of union sizes. 1.5" x 1.5", 2" x 2", 2.5" x 2" and 2.5" x 2.5". These are simply terms for the imperial pipework that the pump unions glue onto, the best way is to measure the outside diameters of the threaded union connections and use this conversion guide.

1.5" Union - 62mm thread diameter

2" Union - 78mm thread diameter

2.5" Union - 93mm thread diameter
