Sump Pumps
Zoeller Service & Repair in Marietta, GA
Zoeller sump pumps, including the well-known M53 and M98 models, protect Marietta basements and crawlspaces from flooding — but only when they're actually working when a storm hits. We repair, test, and install Zoeller pumps with same-day service.
Know the Signs
Common Zoeller Issues We See
The pump doesn't activate when water rises. Often a stuck or failed float switch, the component that triggers the pump to turn on.
The pump runs constantly, even without heavy rain. Can mean the float switch is stuck in the "on" position, or the pump is undersized for the water inflow.
Unusual grinding or rattling during operation. Sometimes debris in the pit, sometimes a sign the motor or impeller is wearing out.
The pump hasn't been tested in over a year. A pump that fails during a storm is a problem you only discover too late — testing now catches issues before they matter.
The battery backup doesn't seem to be charging. Worth checking before storm season, since backups are often what keeps the pump running during a power outage.
How It Works
Our Process for Zoeller Repairs
We test the pump under real conditions
Pouring water into the pit to confirm proper float activation and drainage.
Float switch, impeller, or full unit replacement
Whichever the diagnosis points to.
Battery backup check if your system has one
Since backups matter most exactly when the power is out.
Common Questions
Frequently Asked Questions
How do I know if my Zoeller sump pump is working properly?
Pour a bucket of water into the sump pit and watch for the float switch to trigger the pump, which should then drain the water. If it doesn't activate, it needs attention.
What's the difference between Zoeller's M53 and M98 models?
Both are popular submersible models; the M53 is a common standard-duty choice, while the M98 offers higher horsepower for homes with more water intrusion.
Should I add a battery backup to my Zoeller pump?
Yes, especially since storms that cause flooding often also cause power outages — a battery backup keeps the pump running when you need it most.
How long do Zoeller sump pumps typically last?
Most Zoeller pumps last 7-10 years with normal use, though sump pit conditions and how often the pump cycles affect that.
