Grundfos Universal Circulation Pump 10-0139-K

Great Pump

Did the job very well, more power than my original pump, very quiet, and is installed in a difficult situation, a small hot tub, with little working space.

Great pump, great service

Ordering went smooth and price was good. Pump is really quiet and 3 speed is is good as I am using it on low. Using it for ozone with a grey plastic injector plus turbo mixer. Even low speed has more than enough flow and it is pretty much silent. This new design with the universal barb fittings is the way to go.

Great replacement for my j315 jacuzzi

Grundfus pump was a perfect replacement for my j315 jacuzzi tub. Everything was plug and play!
