Determine Pump Plumbing Size

Plumbing size is very important, but a lot of people get it wrong and end up ordering the wrong pump. Most spa pumps use either 1.5" or 2" plumbing fittings, and a few have 2.5" intake suction. These are pipe call-out sizes, not fitting measurements.

With the pump unions removed, measurement is simple. The easy way to get it right for most* pump brands is by measuring the overall outside diameter (0.D.) of the pump's threads:

1.5" Pump thread measures approx. 2-3/8" O.D.

2.0" Pump thread measures approx. 3" 0.D.

2.5" Pump (intake) thread measures approx.3-5/8" 0.D.

*Most pumps normally have a 2.0" discharge thread fitting, which measures about 3"O.D. Some brands of pumps (such as Hayward, Jacuzzi, and Sta-Rite) use non-standard fittings with different dimensions. Please contact our Parts Technical Help for assistance with these if in doubt.

Pump wet ends can be rotated in 90* increments. Loosen the pump's four through bolts from the back of the motor and pull them back enough to disengage. Then rotate the wet end to the desired position, realign and re-tighten the bolts.
