Zoeller M63 Sump Pump Review: Customer-Tested & Approved

From my own experience I have developed a high opinion of the Zoeller M63 sump pump (Model number 63-0001). You cannot buy a better sump pump that equals its performance in basements, yards, septic tanks and more.

However, I analyzed 81 customer reviews to get a wider view of what other customers think about it. So, 45 of those 81 customers rated it at 5 stars. Of course, there were a couple people that were not happy with it.

The Zoeller M63 sump pump is part of the Zoeller Premium Quality line of sump pumps. Its premium quality comes from replacing plastic parts with cast iron parts that will last much longer. Plus, the internal parts of the on/off switch inside of the pump has been improved vs the Zoeller M53 pump. See my Zoeller M53 review.

The M53 pump has one electrical contact bar inside of the switch case that closes the electrical circuit that starts the motor. That contact bar is the first part to fail on any Zoeller sump pump. So, in the premium quality Zoeller M63 sump pump they added another contact bar which makes the circuit immensely longer lasting.

Which is the main reason the Zoeller M63 has a 5-year warranty instead of 3 years for the lower priced M53 model. However, there are some other improvements that add to the M63’s premium quality rating and longer warranty.

Such as, adding another Viton boot seal to prevent water from entering the motor through the switch case. The switch case is where the metal rod attached to the float ball enters the sump pump housing. So, this additional Viton seal also adds to the longevity of the Zoeller M63 submersible pump.

Two other improvements that are nice to have are:

  • The 10-foot-long power cord, which is a foot longer than some other Zoeller pumps. That extra foot of power cord just might reach that electrical outlet you want to use.
  • Additionally, the power cord has an LED lighted power plug. Which makes it super easy to know that there is power to the pump. I make a habit of checking as I walk by for some other reason. It just takes a glance and I relax a bit more.

O.K. lets jump into what the other customers think of the Zoeller M63 submersible sump pump.

The first time I helped to install a drain tile and basement sump pump system was 1978.

Since then I have worked for a city water utility where I worked with and maintained pumps.

My rental properties and personal homes all needed sump pumps.

As a modular home dealer/builder, those new homes needed sump pumps.

I put that experience to good use by providing reliable, useful, and practical advice on buying, using, and maintaining sump pumps.
