Rated 5 out of 5 by 1reviewer.
Rated 5 out of 5 by I use this pump on my outdoor wood boiler. This is my second year using this pump. It runs 24/7 durning the winter months. Temps rang from 70 to 225 degrees Fahrenheit. It pumps the water from approx. 11 feet up with no problem. This is a great pump for the price!!! January 22, 2014
