Sump Pump Replacement in Chesapeake Beach, MD

The Problem

A homeowner in Chesapeake Beach, MD (20732) discovered water in their finished basement after a heavy rain event. The sump pump had failed silently — it had stopped working at some point before the storm, and the homeowner had no way of knowing until water appeared.

The basement had approximately 2 inches of water throughout, affecting flooring, drywall, and stored belongings. The pump was 11 years old and had never been tested or serviced.

The Diagnosis

We removed the failed pump and inspected it. The float switch had seized in the down position — the pump motor was functional, but the float switch that triggers it had failed, so the pump never activated when water entered the pit.

The pump itself was also showing signs of wear consistent with its age. Given the float switch failure and the pump's age, replacement was the appropriate recommendation rather than a float switch repair on an aging pump.

We also noted that the discharge line had a check valve that was functioning correctly — the failure was entirely in the float switch.

The Solution

We installed a new 1/2 HP submersible sump pump with a reliable vertical float switch. We also installed a battery backup sump pump system — a critical addition for a home in Chesapeake Beach, where proximity to the Bay means power outages during storms are common.

The battery backup system activates automatically when the primary pump fails or when power is lost. It provides approximately 8 hours of pumping capacity on a full charge.

We tested both systems thoroughly before leaving — filling the pit to confirm both the primary pump and the battery backup activated correctly at the proper water levels.

The Outcome

The homeowner has had no water intrusion events since the installation, including during two significant rain events. The battery backup system has activated once during a brief power outage, performing exactly as designed.

Key Takeaways

• Sump pump failures are often silent — the pump stops working before you know it
• Test your sump pump twice a year by pouring water into the pit
• Battery backup systems are essential for homes near the Chesapeake Bay
• A pump more than 7–8 years old should be proactively replaced
• Float switch failure is one of the most common sump pump failure modes
