About the Grundfos 96860207

This Grundfos MQ pump is compact and extremely easy to install. The pressure switch and tank are built-in, and it is self-priming and water cooled with a very low noise level. The outlet pipe connection can be angled up to 5-degrees to fit your existing pipe-work, and it's simple and easy to operate. The settings are clearly indicated on the user friendly control panel with indicator lights for on/off, auto reset, and an alarm indicating dry running or overheating. The Grundfos MQ3-45 is built for trouble free operation, and its construction of corrosion resistant materials means it can be used for clean water. The anti-cycling feature prevents the pump from repeatedly starting and stopping in the event of a dripping tap or a minor leak, and in the even of no water availability, the pump will stop to protect itself and restart automatically when water is available again.

Quiet but leaked after 28 months Rated 2 by Davis
  No, I do not recommend this product.
We bought this pump for all its features only to have it leak after 28 months. It runs quiet but I did expect to get at least 5 years out of this pump. I am going to buy another one to see if I get the same result. The worst problem is that no company has a reliable pump that lasts.
