Zoeller M53 Features & Specifications Summary
Zoeller Sump Pump M53 Consumer Reviews rate this pump well; 4.3 stars out of 5. It is built with cast-iron housing and a vertical float switch. It is built to last; to keep it running for ten plus years, the float-switch will need to be replaced every 2-3 years depending upon how frequently it is used. See what consumers are saying about it.
I've had my Sump Pump M53 over 12 years. Before I figured out it needed a new switch, I bought another M53. I installed the new M53 and am keeping the old Zoeller with the new switch as a backup. We have a very high water table and the sump-pump runs every 2-3 minutes most of the year. You won't find a much better one out there that can run like this for 12+ years and only need a $20 switch. It is oil-filled for long life. It is quiet and reliable. I'll never run anything other than Zoeller.
I bought a Zoeller M53 23 years ago and it is still running. It only runs when we get heavy rains; however when it rains it is a work horse. It moves the water up an eight foot vertical lift and pushes it another 40 feet out to the street. In the past 23 years we have had some very heavy rains to the extent of area flooding, probably every 5 years. This pump has NEVER failed in ANY way yet. I am very happy with it.
I am very happy with my Sump Pump M53. It is very heavy and built to last. The housing is cast-iron. It was easy to install. I read the manual and found out I am to replace the float-switch every 2-3 years depending upon usage. The float-switch is the weakest part of the pump. So I bought a replacement float-switch so I have it ready in case the switch goes out before I change it.

If your current pump runs a lot during heavy rainstorms and then runs very little during no rain periods, we recommend you purchase the N53 which comes without a float switch. Installing an external separate float switch allows you to customize the ON OFF points for the motor which decreases motor short cycling and extends the life of the motor.
Our favorite external switch is the HC6000 which is electronic, has no moving parts, is not affected by water contaminates or chemicals and has a lifetime warranty. We installed ours in 2011, have done no maintenance to it and it is still working perfectly.
Each time a new pump is installed it is highly recommended the check valve be replaced as well because they do fail.
Our favorite is the Quiet Check valve because it is so quiet. The Traditional check valve is also available.
