Excellent circulation pump
By Paul H.
Scottsdale, Arizona
Purchased 08/08/2019 |
Review Posted 09/02/2019
Replaced a Grundfos circulation pump that was 14 years old. The water In Phoenix is very hard so that’s pretty good. The new pump has been updated but it fit perfectly. Make sure you save the cord from your old pump as this pump doesn’t come with a cord. Also make sure you label the old cord and hook up the power cord with the correct polarity so the pump circulates in the proper direction. Couldn’t be more satisfied.

Review Posted 04/16/2019
I installed a Grundfos pump 18 yrs ago it has been running 7 days a week only shutting off for 5 hrs at night. The timer did give out but I just installed a plug in timer. So as I'm building a new house it was a no-brainer to go with Grundfos again.

This was a replacement for a previous unit that failed due to a power surge. I am very pleased with this one and find it is much easier to program with the self-contained timer.

Answered by Ken, the eComfort Product Expert
Can this pump work upside down? That is installed vertically but the flow goes from above to below?

Does this Grundfos 59896775 come with a built-in timer?
Dan

My pump froze. Is there more to changing out the pump than shutting both gate valves and undoing the 4 bolts?
