I would purchase this pump again if necessary.
I use this pump as a booster pump because our city water pressure is low. I could not be more pleased. It works flawlessly.

Quality pump
Good directions, easy to install, overall quality pump. A bit louder that my last one. I bought it to prevent corrosion inside plumbing system.

Great Product
Getting this pump completely solved all the problems we had with rust in our drinking water coming from the other pump. If you are using a pump to delivery RO processed water to your house DO NOT get a cast iron pump!!

From now on I'll only buy Grundfos pumps
I bought this pump to replace a pump I bought at a big box home improvement store that barely made 40 psi. This pump goes to over 100 psi easily even though I only need 60 psi. My first pump was a Grundfos that I ran for years until it was run dry for an unknown amount of time and burned up. I won't buy any other brand from now on. These things just work like they're supposed to and the way you expect them to.
