Rated 2.7 out of 5 by 7 reviewers.
Rated 1.0 out of 5.0 by dumb and dumber The float guide rod is made out of regular steel that rusts and then breaks . It would cost almost nothing more to make the rod out of stainless steel but no, they save a few pennies and make a 1hp sump pump worthless after the rod breaks from rust. There is no way to get the part since you get put on eternal hold at Wayne. December 11, 2014
Rated 5.0 out of 5.0 by powerful pump my only hesitation on the large pump was alot of reviews stated it was noisy. so far it is just as quiet as the 2 year old small pump i had. pumps alot of water fast July 23, 2015
Rated 1.0 out of 5.0 by Plastic Impeller Plastic impeller broke after 9 months. Tried to replace and broke ceramic spacer behind impeller. Five year warranty is a joke. March 31, 2015
Rated 5.0 out of 5.0 by Monster power sump pump This is a really good pump. I have previously tried several types and manufacturers and the quality of this unit is superior. The stainless steel and cast iron construction makes it extremely durable. The 1hp motor has no problems keeping up with the worst storms we see in this area (Ohio). As long as you keep power to this pump, it will keep your basement dry. July 29, 2014

Rated 1.0 out of 5.0 by Very flimsy. The ball comes off and little L- shape bar that holds the ball does not stay in its assembly. The product will not work correctly out of the box. Please be prepared to make two modifications to the pump in order to get it to work. Please purchase the check valve to stop the back flow. July 9, 2013
Rated 1.0 out of 5.0 by Excessive noise Unsuitable for residential usage plus the prohibitive high cost. Simply far too excessive noise when the pump is on. May 13, 2014
