What Customers Are Saying

Customers overwhelmingly praise the pump for powerful performance, quiet operation, and robust cast iron construction. Many highlight easy installation and seamless compatibility with existing systems. Reviewers consistently describe it as quiet compared to older models and highly effective at handling heavy water flow. However, some report premature failures—particularly float switch malfunctions within months and motor failures after warranty expiration—raising concerns about long-term reliability. Despite these issues, most customers consider the durable build and strong initial performance worthwhile.

Sump Pump

This is a well built cast iron sump pump. I have used this pump before and it lasts forever.

Exact replacement

Would Recommend

The pump is a match to the one I was replacing; brand, horsepower, and physical size. Being alike made it easy and quick to complete the replacement.

100% tested at factory - NOT

Would Not Recommend

Picked up pump at my local Lowes. I noticed right away that the outer box was beat up badly. I opened the outer box and the inner box looked just as bad. I opened the inner box and the pump looked OK. I got home and removed the pump from the box. Half of the machine screws holding the impeller cover were missing, and the half that were there were just barely in. Zoeller claims that each pump is 100% tested at the factory. That's obviously not true.
