Works as described

Review Posted 05/08/2017 
I purchased this pump to replace a single speed grundfos pump that was unable to recirculate the hot water adequately in our 4300 square foot house. After experimenting with all of the settings, I have it set on the maximum flow which does an excellent job of maintaining hot water to the opposite end of the house.

Replaced old unit--this one runs smoother. If it quits working you will know by looking at the digital readout. Appears to be much better quality especially the stainless steel unit.
