Customers praised this spa circulation pump for being "very quiet" and easy to install with clear wiring instructions. It fits as an exact replacement at a competitive price with fast shipping. Most found it "works great" with strong pumping performance. One shopper noted it's "a hint noisier" than expected, though still acceptable.

Two weeks in, it’s running great and is very quiet

Two weeks in, it’s running great and is very quiet. Six months in - better time to get a true rating.

I want to thank Dustan for his quick response and his recommendation of the pump. Shipping was fast and the pump was very reasonably priced. It was an exact match and it worked great and was easy to easy to install.
Thanks again,

Works Like a Dream

The old pump(10 years. old) was exactly like this circulation pump. Installing went really smooth after converting to 110v

A little noisier

Replacement of the pump went fine. Since it is a dual voltage pump, you have to be mindful of the wiring arrangements. It is sent as a 230v pump, mine was 120v. The instructions were crystal clear and it went in easily, everything lined up like the original. The only complaint is that the motor is a hint noisier, but livable. It will be fine once I button up everything.

Circ pump

Direct replacement over 1/2 the price of name brand. Very quiet and works great so far. As far longevity, can’t say it is only a couple weeks old.

Great First Experience

Excellent value

Installed very easily and pumps nice and strong. I'm replacing a Balboa seized. It's actually a little louder than the Balboa but I prefer that because I want to hear that it's working. My old pump was so quiet I couldn't tell it failed. If this pump gives me anywhere close to 7 years that would be a steal.
