How to Determine Spa Pump Plumbing Size

Pump plumbing sizes are nominal, and not actual outside diameter (OD) of the threaded intake or discharge. Use a tape measure and check your old pump thread size against this sizing table for most* spa pump brands:

Plumbing Size		Pump Thread O.D. (approx.)
1.5"		2-3/8"
2.0"		3"
2.5"		3-5/8"

Some brands of hot tub spa pumps (such as Hayward, Jacuzzi, and Sta-Rite) use non-standard fittings with different dimensions. Please contact our Parts Help desk if you need assistance with these.
