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.
Great Canadian prices aside, buying from Pool and hot tub depot in Canada provides access to one thing you can't get anywhere else: our expert technical support. Installation questions or need assistance finding a compatible replacement part? We're here to help!

    Purchased the pump online and picked it up at the London store 2 hours later. Great service and price. They're not just an internet dealer their store in London is also their warehouse, you can actually walk in and purchase what you need at online prices. My hot tub parts store from now on.

  3. Wow

    Wow you guys/gals are real good.

    Ordered the new pump yesterday, got it early afternoon today, wired it up, installed it, and the tub is warming up right now. Brilliant that you automatically include new O-rings.

    Being a novice, would not have thought of that important option. Happy hot-tubing again later this evening.

    Thanks so much.

    I ordered this pump on Sunday and had it on Tuesday midmorning. It fit perfectly, I was worried about the fit as my hot tub is 16 years old. It dropped right in and was running in 10 minutes. Perfect!

  9. Great prices from a Canadian store

    Posted by on

    Needed 2 new pumps for my hot tub that got fried in a power surge during a storm, went to a couple of local dealers here in Calgary and was shocked it was going to cost me almost $1,500 for 2 new pumps, $740 each!

    Found this company on google and could not believe that they had the exact same pumps for almost half price, called to confirm that it was actually the correct price in Canadian $ and they would be shipped fron in Canada and ordered them, they got delivered next day, shipped from a warehouse in Calgary.
    Will definitely recommend all my friends here good service and good prices.

    Thank you,
    Peter in Calgary

  10. 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.
