Simple pumpreplacement
A simple replacement for a failed pump. I wanted the same as last - not the newer digital model. I even saved the old timer from the failed pump. Shipped very quickly, and worked straight out the box. Thanks.

Is this item Stainless Steel as advertised???
I was trying to contact the Seller but was not able to find any information on Amazon so I thought I would write this in the review. I ordered the same Recirculation as the one we had that went out and when we received this new part, the Plumber came to install yesterday and said the box says it is Stainless Steel (as the one I had) but when he looked at it and took the photos I am providing below, the Plumber said it is NOT stainless steel and felt we were overcharged because of the product. We had to install it because we had to run the water for so long to get hot water or else I would have returned it.

Quiet & Dependable!
I installed this on my hot water recirculation loop and it just hums along. It has a timer, so it automatically turns off at 10 pm and back on at 4 am, so no wasted energy. It's quiet and been dependable so far! (Almost a year of run time!)

Smooth installation, reliable
Good replacement for my customers. With the union kit it was a flawless transition.

Quality
This was a replacement the same circulating pump that was old. My installation required a minor configuration change due to the age difference of the two pumps. The new pump is now working perfectly fine and I am happy with it. I would purchase again from Amazon if necessary.

Grundfos Circulator Pump does its job
Easy to install. Works fine. The only problem is that it is a bit noisy. I understand that may be normal with a Grundfos pump like this.

Do not buy
Ours broke in a few months. A big crack ruined everything. Cannot get a refund. Company does not exists. No phone number. Called several times. Amazon not helping. Year warranty worthless.
