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:

So far so good
My old pump was 5 years old and started making high pitch sound so I purchased this on-line and found it to be the best priced pump out there. After installing last night, it was incredibly quiet, was very pleased. Taking the old pump out was tedious but installing the new pump was simple. No clear directions with the new pump but youtube helped that part out. The power cord connection assembly was simple and straight forward, just know what color cord does what (high/low/common). Also, b/c this is a 115v pump it takes just a bit longer to heat up my Dream Maker spa. After 12 hours, the water temp was already up to 94 degrees. Great product and warranty! Enjoy!
