Zoeller 803-0001 Reviews & Ratings

Expert Recommended Review

Review Posted 04/15/2019
Are you constantly having problems with your pump getting clogged with everything from paper towels to washcloths to the kitchen sink? Well, not really the kitchen sink, but this Zoeller Shark 1/2HP Cast Iron Grinder Pump will handle pretty much anything you throw at it.

Designed specifically for residential applications, this pumps addresses the problems associated with clogged impeller problems due to the introduction of foreign matter that is not normally associated with human waste.

This pump comes with Zoeller's Stainless Steel Tri-Slice® Cutter Technology that includes 3 independent cutting channels that provide over 250,000 cuts/min. The efficient 1/2 HP electric 7-Amp motor typically allows for installation with a standard 15-Amp circuit (but always check your local code or National Electric Code) and with the 1-Year Limited Warranty, this pump earns our recommendation.

So Far So... Great
By Aaron M

Purchased 12/25/2024 | 
Review Posted 01/16/2025 
I previously had a standard sewage ejector pump, but this one is working amazingly so far. It feels like it has better performance, with longer cycles and fewer short pump-outs. I also don’t have to worry about anything getting stuck in the propeller.

So far, so good—now I just need to see how long it lasts!

Very Pleased With This Product Thus Far.
By Kenneth D. 
Bolingbrook, Illinois
Purchased 11/08/2019 | 
Review Posted 12/01/2019 
First of all, the pump arrived at my home way ahead of schedule. I was very pleased with the early arrival. Packaging was top notch. It was obvious the pump was very well constructed, well built, and extremely sturdy. Installation was a breeze. I was very surprised at how quiet the pump runs. I wish that I could see what was actually going on inside that ejector pit (then again, maybe I don’t ). All I can say is that the pump starts and stops periodically which is an indication that good things are happening. As far as I can tell, the Zoeller M 803 is a winner!

Great Solution To A Tough Problem
By Michael K.

Review Posted 06/19/2019 
I have a trench drain in front of my garage that had a screen that kept getting clogged with leaves, which resulted in my garage getting flooded. I removed the screen & installed this grinder pump as a solution and it has worked perfectly!

You should never use the cord to lift any pump out of the pit.
