Wet End Orientation

 

 


Orientation of wet end.

Pump wet end can be oriented in 90 Degree increments, up, left or right as shown in illustration on the right. Pump will ship with discharge directed up. To change the discharge orientation, 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.  

 
Pump Intake Size
 
Important
Determine the pump plumbing size by measuring the outside diameter of the wet end male threads. Plumbing sizes for hot tubs are nominal, and not actual outside diameter (O.D.) of the the threaded intake or discharge. Once you have removed the pump, use a tape measure to check your old pump thread size and compare to the sizes below.
 
 
If your pump thread O.D. is (approx.) 2 3/8",  Then you'll need a pump with union size 1 1/2".
If your pump thread O.D. is (approx.) 3.0",     Then you'll need a Pump with union size 2.0".
If your pump thread O.D. is (approx.) 3 5/8",  Then you'll need a Pump with union size 2 1/2".
 
Please note!
Some brands of hot tub spa pumps have non-standard threads and use fitting sizes with different dimensions. These brands are: Hayward, Jacuzzi and sta-rite.

    Don't have to buy my parts in the US anymore since I found this store in Canada, they have prices close to US prices and ship from place in Vancouver to BC customer which is a plus. Good prices and great service.
