Rated 4.7 out of 5 by 6reviewers.
Rated 5 out of 5 by We have a facility that has five pumps Zoeller sump pumps and have had good experience with these units. Our last purchase was to replace 1/3 hp pumps with 1/2 hp because 1/3 hp pumps were struggling to keep up with inflow. In one case our wet well is small and under certain inflow conditions the pumps cycle with less than 30 seconds of off time. They tend to work year after year without need of repair. June 29, 2015
Rated 4 out of 5 by The aplication we use this in, it works perfectly. We ordered these many times and will continue to. The price is alittle high (I have found them cheaper elsewhere--but usually have to wait 5+days to receive). We usually need it NOW. So will call or next day delivery is awesome. July 24, 2013
Rated 5 out of 5 by This isn't a trash pump so it doesn't perform well if there is alot of large debris in the water, but other than that, these pumps work great and I can rely on it working. I would recommend this pump. September 5, 2012
Rated 4 out of 5 by durable product but low cleance The pump is great we have had one of ten years but the clearance to the floor is not very high and it allows a lot of junk into the pump. March 28, 2012
