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.  

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 (aprox.) 2 3/8",  Then you'll need a pump with union size 1 1/2".
If your pump thread O.D. is (aprox.) 3.0",     Then you'll need a Pump with union size 2.0".
If your pump thread O.D. is (aprox.) 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.

  1. Thank you for the great service

    Posted by on

    Just want to thank you for the great service, I placed an order on Monday, then changed my mind and modified the order Monday afternoon, and on Tuesday morning the Hot Tub motor arrived before 10am
    That is impressive service, It was a pleasant surprise to see the motor arrive the next day like that considering I live in Kamloops B.C.

  2. Excellent Service and product from Pool&Hot Tub Depot

    Posted by on

    Ordered this pump from Pool & Hot Tub Depot at a cost of about $200.00 less than what I was quoted from where I bought my Hot Tub. The exact same pump. Not only that but my local dealer told me it would take at least week to get the pump to me. Pool & Hot Tub Depot had the pump delivered to my door - at no charge - within a day and a half! I called the store to confirm a few things before I ordered and had all my questions answered completely by an obviously very knowledgeable person on the other end of the line. Just a pleasure buying from Pool & Hot Tub
