Review Posted 05/04/2025
I hope that this pump lasts as long as my last pump 25 years ? it was still working I believe the switch started sticking once in while. So thought it was time to replace. Didn’t want it to break in a bad rain storm. Would highly recommend Zoeller pump

Reliability

Review Posted 04/09/2025
The float switch is the problem. It only can last about 3 yrs. What are you going to do with it afterwards? It is more expensive for only 3 years. Replacing the switch and handle seal are expensive.

Great Pump
By Mark R
Michigan
Purchased 03/10/2025 |
Review Posted 03/31/2025
Upgraded from the M53, that lasted about 8 years before the float stuck up, causing basin to overflow in my basement. I live in an area with dense clay, so my pump runs very often. I installed the M63 in last week, so far it has run great. It appears to pump water out faster and is slightly quieter.
UPS delivered the pump and box was destroyed and part of the pump was sticking out of the box. I called and they replaced the pump.

Zoeller Pumps Are Very Dependable
By John F.
Anniston, Alabama
Purchased 05/10/2021 |
Review Posted 06/23/2021
We have several of these pumps located under the Sanctuary of our church that was built on top of a spring. The sump pump pits fill with water and cause the pumps to cycle 6-7 times per hour every day of the year. (The incoming flow rates don't change much based on changes in the seasonal rain fall.) We've not yet had one of these M63's fail and we can't recall how long ago these were installed.
I recently bought one to replace one that had a sticky float switch. Perfect fit for the original pump. I will replace the switch and put it on the shelf for a spare for when we finally have one go bad.
Our maintenance staff loves the new feature of the LED light on the power cord.

Bad things happen in my basement if the pumps don't run. Have 2 sump pits and it sounds like Niagra falls in my basement in a rainstorm. These are the only pumps ill use.
