Sump Pump Installation & RepairSump pump not working before storm season? Battery backup options, failure signs, and how to get connected with an independent local plumber.
View all Sump Pumps servicesA sump pump usually fails quietly and reveals itself at the worst moment: water rising in the pit during a storm while the pump sits silent. The common culprits are a stuck or failed float switch, a tripped breaker or GFCI, a clogged impeller, or a discharge line blocked by ice or debris. Because the pump only matters when water is coming, a failure discovered during dry weather is actually good luck.
FlowFast connects you with an independent local plumber who repairs sump pumps as urgent service calls. The pro works through the system in order: power first, then the float switch mechanism, then the pump itself, then the discharge path. Many failures are a single failed part, a switch, a check valve, or a clogged intake, and a good pump with years of life left deserves the repair rather than a full replacement.
Warning signs
Signs you need this service
- The pump does not turn on when the pit fills, or you have to jiggle the float to get it running.
- The pump runs nonstop even when the pit is nearly empty, suggesting a stuck switch or failed check valve.
- Water overflows the pit during rain despite the pump running, meaning it cannot keep up or the discharge is blocked.
- The unit makes grinding or rattling noises, vibrates violently, or trips the breaker when it tries to start.
What to expect
The process, step by step
The pro confirms power at the outlet and breaker, then manually lifts the float to see whether the pump responds.
They inspect the float switch for sticking, tangling, or failure, and check the impeller intake for debris.
The discharge line and check valve are tested for blockages, ice, or a failed valve letting water flow back.
Failed parts are repaired or replaced, and the system is tested through full cycles under simulated inflow.
Prevention
How to avoid this problem
- Pour water into the pit every few months to verify the pump still activates and shuts off on its own.
- Keep the pit covered and clear of debris so the float moves freely and the intake stays unclogged.
- Listen for changes in sound or cycle length, since new noises often precede a failure by weeks.
