Works fine
By William P. (from Cimarron, CO) on 10/18/2012
Bought this pump since an earlier one lasted over 8 years (warrantied for 2 years). More than satisfied with the quality and performance.
Great product
By Jeff (from Delray Beach, FL) on 6/7/2012
I own a house in Florida where the master bath is all the way on the opposite side of the house and the plumbing is in the slab. Adding a return line is not an option and we had to run the water for 5 minutes to get warm water. This package was easy to install and worked like a champ.
It works as advertised
By Al (from Chisago City, MN) on 5/9/2011
I live in a towmhome and all the water pipes are underground and it takes the hot water a long time to reach the tap. I now have hot water at the tap in a few seconds rather then minutes. It saves water and more importantly hot water.

This pump does not require a return loop and is not designed for a system with return hot water line. If you already have a return line, you can use any circulator pump from Grundfos Comfort System Line except this one.

Like the price for combo. But I do not need or want the timer. Do you have a package without the timer.

This is the only re-circulating pump that does not require return line and Grundfos makes no other variations of it.

Why would I pay for a stainless steel pump housing when I can get a cast iron housing cheaper? I intend to use the pump for hot water recirc with cold water line as return.Thanks!

Cast iron circulator pumps are designed for use in closed-loop heating systems only, where there's no oxygen (air molecules) in the water. Oxygen-rich water quickly corrodes the circulator shortening it's lifespan and reducing system efficiency. Both stainless steel and bronze circulators are equally suitable for use with oxygen-rich water.
