Side vs. Center Discharge

Orientation of Wet End

Pump wet ends can be oriented in 90º increments to meet your installation requirements. 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.  

Wet ends can be rotated

How to Determine Spa Pump Plumbing Size
by measuring O.D. of wet end male threads

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:

more powerful and quieter
Ryan and Brian gave me the 2 correct motors for my tub with the pictures I took of them sent by email, thus keeping the whistling and leaking ones installed till the new ones came in. Wiring was easy once I saw the electric connections identified with H,C, and L for high, common, and low. Free shipping, great tech help, and saved money.

Excellent Pump - We Have Bought Two
We have a Cal Spa that is almost 9 years old. It came with three GE 5 HP pumps. I replaced Pump 3 probably two years ago and it's running strong. Pump 1's bearings were failing so I ordered a this replacement over a year ago and it sat in the box in the garage until two weeks ago when I finally decided to replace Pump 1. Pump works great, moves water/bubbles around as a spa pump should. One thing I'd like to mention if you have a Cal Spa. The paper wiring diagram that came in the box should red wire to low speed and black wire to high speed. This was incorrect and I popped 30a spa pack fuse. No biggie. But in Cal Spa's running Pump 1 in two speeds, red is high speed and black is low speed. These are priced right too. You can't go wrong. Dave D. (Retired Navy)
