Rated 4.8 out of 5 by 5 reviewers.
Rated 4.0 out of 5.0 by Sturdy and Reliable Pump Installed this sump pump about a month ago and seems to be doing the job just fine. Like the heavy cast iron base to keep the pump in place in my sump pit and prefer the tether float switch which has a bit higher on-off range so will pump more volume compared to the vertical float switch type.

Rated 5.0 out of 5.0 by Prior Wayne sump pump lasted 20 years Easy purchase, easy installation. Only purchase a cast iron sump pump. December 27, 2011
Rated 5.0 out of 5.0 by Works well, quiet, no problem This replaced an older unit that was damaged by saltwater from Hurricane Sandy. The old pump still worked but the float switch which was the level type began to stick 6 months after the storm and the side bolts began to rust from the salt water. The pump still worked well and pumped 3 feet of saltwater out of my crawl space in two hours once the power came back on. November 16, 2013
Rated 5.0 out of 5.0 by Great quality. Built to last. This pump is built like a battleship. The body is cast iron. If anything on the pump fails, it can be disassembled and the failed part replaced. January 15, 2013
Rated 5.0 out of 5.0 by It went together nicely and fast, a no hassle installation. It went together nicely and fast, a no hassle installation. March 11, 2014
