Center Discharge

Waterway Pool & Spa Pumps
Waterway Center Discharge Spa Pump

1.5" Inlet/outlet
Thread size 2 3/8" (outside dimension)
Shipped with (2) 1-1/2" Unions

Replacements for Aqua-Flo, Premier, Hayward, PacFab, Sta-Rite, Waterway and others
Not Self Priming, water must be above pump head in order to operate
Note: There is no industry standard for Unions.
The various brands have their own unique style, which means you must use the unions provided with the spa pump.
This will most likely involve cutting off your old unions and installing the new ones shipped with the hot tub pump.
1-1/2" PVC means 1-1/2" schedule 40 PVC. Your PVC supply lines slide into the pump union not the threaded inlet/outlet.
