Grundfos15-178-6291 Low-Flo Circulation Pump, 31842

I use these often for hot tub repairs... better than OEM circulation pumps in many hot tub brands.

First pump arrived broken. Contacted sell they replaced it quickly. The replacement pump had a strange rattle. I figured I would give it a shot. It doesnt work either.

My husband and I bought one of these from a different seller a little more than a year ago. It lasted just about a year and thw company would not honor the warrantee. We need that particular pump for our jacuzzi, which my husband uses for back pain relief. We hope this one lasts longer as it is a big expense for us.

pump really performs / quiet and efficient

Its not a bad pump but not god for hot tubs but the return was easy and no fuss

Works as good as original which was used on a spa 24/7 to recirculate ozone for last 10 years.

I bought my pump from you in June, 2018. It died today Oct29. Rusted from the inside out. Do you offer a replacement. My original hot springs pump lasted 10 years. This was a lot of work to adjust and install this new pump. It's not a 1 for 1 replacement. I did add my old power cable, as directed. Now I have to start over again. It's been leaking for a few weeks or months by the amount of mineral build up inside the cabinet. This sucks. Drain 550 gallons of new treated water, clean cabinet and find and install another pump

I used this Grundfos pump to replace Laing circulation pump that failed in my Hot Tub. It was a bit tricky to replace a pump which uses 3/4" tubing with this unit which has barbs for 1" vinyl tubing. The Grundfos outlet location is not very flexible so you'll need to be creative if you intend to do this conversion. If you find yourself doing this job during the winter months, I suggest a hair dryer to warm up the tubing so it will slip over and conform to the hose barbs easier.
