The Conodoguinet Creek drains a large watershed across central Cumberland County before emptying into the Susquehanna River west of Harrisburg. Properties in Silver Spring Township, the northern sections of Mechanicsburg Borough, and the communities along the creek corridor experience faster groundwater table rise during spring snowmelt and heavy rain events than the higher-elevation sections of the West Shore. The sump pump in a basement near this corridor is one of the most important pieces of plumbing equipment in the home, and it is also among the least tested.
Why Spring Is the Highest-Risk Season for Sump Pump Failures
The timing of spring sump pump failures is not coincidental. The events that cause the most significant groundwater infiltration on the West Shore are the same events that are most likely to cause power outages. A heavy thunderstorm or prolonged rain event raises the water table around the home, increases sump pit infiltration volume, and taxes the pump's motor precisely when the grid is under stress from the same storm system.
A primary pump that has been sitting without operation through a dry summer, fall, and winter is being asked to perform at full capacity during the season's first significant water event. Pump motors that are seven to ten years old, float mechanisms that have stuck in the down position from lack of use, and discharge lines that have accumulated debris or partial ice from winter are all failure modes that appear in the spring.
How to Test Your Sump Pump Before Spring Arrives
The simplest and most reliable test is to pour a bucket of water slowly into the sump pit until the float triggers. The pump should start promptly within a few seconds of the float rising to the trigger point, run until the pit is drained to the pump shutoff level, and then stop cleanly.
A pump that does not trigger at all when the float rises has a failed float switch, a failed motor, or a lost power connection. A pump that runs but does not drain the pit has a failed impeller, a clogged intake screen, or a discharge line that is blocked or frozen partway to its outlet. A pump that starts normally but runs continuously without shutting off has a float switch stuck in the triggered position.
Any of these failure patterns in a pump that is seven years old or older is a reason to evaluate replacement rather than repair. A pump that fails its bucket test in February or March is going to be asked to run in a storm event in April or May.
Is Your Primary Pump Sized Right for Your Basement?
Not every sump pump installation is sized for the actual infiltration volume the home can experience during a peak event. A standard residential sump pump handles moderate infiltration volumes, but a property in the lower-elevation sections of Silver Spring Township near the Conodoguinet corridor, or a basement that sits below the seasonal high water table in any West Shore community, may need a higher-capacity unit.
Signs that your current pump is undersized include: the pump runs continuously during a moderate rain event without the pit draining, or the water level in the pit rises despite the pump running. If either condition appears during a spring storm, the pump capacity does not match the infiltration rate in that basement.
The Case for a Battery Backup Sump Pump
A primary sump pump operates on household current. A power outage during a storm renders it completely non-functional at the worst possible time. For any basement on the West Shore where flooding would damage finished living space, stored contents, or mechanical equipment, a battery backup sump pump is the single most effective protection addition beyond the primary pump.
A battery backup system operates on a 12-volt deep-cycle battery that charges from the home's electrical system during normal conditions. When the primary pump fails or loses power, the backup activates automatically. Most backup systems can handle several hours of pumping on a full charge, which covers most power outage durations during storm events.
Water-powered backup pumps are an alternative for homes served by Pennsylvania American Water where line pressure is reliable. They use household water pressure to create suction that removes water from the pit, requiring no battery and no electricity. The trade-off is that they consume municipal water while running, which may be a consideration for high-volume events.
If Your Sump Pump Fails During a Spring Storm
When a sump pump fails during active groundwater infiltration, time matters. The infiltration rate into the pit does not pause while you troubleshoot. If the bucket test in February or March revealed a problem, address it before the wet season starts rather than discovering the failure in April.
We respond to sump pump failures as emergency plumbing calls throughout the Borough of Mechanicsburg, Silver Spring Township, the Conodoguinet Creek-area communities, and all of the West Shore service area. We carry common replacement pump units and can often complete a same-day primary pump replacement during business hours, or emergency replacement for calls that arrive in the middle of a storm event.

Scheduling a Sump Pump Assessment Before Spring
('The best time to discover that your sump pump has a failing float switch or a seized impeller is in February, not during an April storm. A pump assessment visit in late winter is a short appointment: we test the pump with a controlled water volume, check the float mechanism through its full travel range, inspect the discharge line for any blockage or freeze damage from the preceding winter, and assess whether the current pump capacity is appropriate for the pit size and likely infiltration rate for that specific basement location.', "For homes in the Silver Spring Township sections closest to the Conodoguinet Creek corridor, and for the lower-elevation properties in New Cumberland and Wormleysburg nearest the Susquehanna River, a battery backup assessment is part of the same visit. We size the backup to match the primary pump's output and the battery capacity required for the typical power outage duration in a spring storm event.", 'If the primary pump fails the test or is more than seven years old, we present the replacement option on site. A battery backup unit that is compatible with the existing pit and discharge line configuration can usually be installed the same day as the assessment. We carry common primary pump models and battery backup units for the most frequent residential sump pit configurations in the West Shore service area.')
A pre-season assessment costs a fraction of the water damage that a failed pump allows into a finished basement during a spring storm event. Call us in February or early March for same-week scheduling throughout the West Shore service area before the first significant rain events of the season arrive.
