M53 Mighty-mate: Ideal for average-sized homes, this 1/3 HP sump pump handles up to 2,680 gallons per hour, perfect for moderate water removal needs. It features a durable cast iron construction and is designed for quiet operation.

If your sump pump stops working, check to ensure that it is plugged in and that the circuit breaker has not tripped. Test the pump by pouring water into the pit to trigger the switch. If the pump does not start, or if you notice any unusual noises or vibrations, contact a professional plumber for service. Do not attempt to repair the pump yourself as this may void the warranty.

The Zoeller M53 and M98 are designed for quiet operation. While no sump pump is completely silent, these models feature a quiet check valve that minimizes noise. Ensuring proper installation and regular maintenance can also help reduce operational sounds.

Both the Zoeller M53 and M98 sump pumps come with a 3-year manufacturer's warranty that covers defects in materials.

A minimum sump pit diameter of 18 inches is recommended for both the M53 and M98 models to ensure optimal performance and sufficient space for the float switch to operate.

It is advisable to have a battery backup system, especially in areas prone to frequent power outages or heavy rainfall. A backup system will ensure that your sump pump continues operating during a power outage, providing uninterrupted flood protection.

Choosing between the M53 and M98 depends on your specific needs:
M53 Mighty-mate: Choose this model for standard residential use where average water volume management is sufficient.
M98 High Capacity: Opt for this model if your home is in a high-risk flood area or has a higher water table and requires more robust flood management.
