IMPORTANT
How to Determine Spa Pump Plumbing Size
by measuring O.D. of wet end male threads
 |
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.
Product notes: 48 frame, approx. 8" diameter. 310-1900
