    Excellent prices, very prompt delivery. The packaging was amazing. Free shipping on something this heavy is an incredible benefit. And the pump was an exact match for its predecessor.

    The pump we ordered works beautifully! Service was good, and didn't take long to get here.
    I would highly recomment this company, if you ever need parts this is the guy to go to.

    The waterway pumps I purchased fit directly without modification, are quiet, and perform like new. I also saved about 50 % over the cost of what the hot tub manufacturer charged and substantal amount in labour by doing the work myself. All in all a great experience.

    First of all Canada Hot Tub Parts was great to work with. Easy ordering, timely shipping and everything arrived as advertised. No hidden costs or hassle. As to the pump it is everything I hoped: quiet, efficient, easy to install . It is doing a great job on our hot tub
