Sump Pump Maintenance & Annual Inspection
Your sump pump is the one moving part standing between a heavy Quad Cities storm and a wet basement. It’s worth keeping it honest.
A sump pump is a mechanical device that runs hardest exactly when you need it most, and fails quietly the rest of the time. Most homeowners never think about theirs until the morning it doesn’t turn on. A little routine attention — and one thorough professional check each year — is the cheapest insurance a basement can have.
How often should a sump pump be serviced?
As a general rule, test your sump pump yourself a few times a year, and have it professionally inspected once a year. In the Quad Cities the most important test is the one you do heading into spring, before the wet season loads it up.
- Every few months: pour a bucket of water into the pit and confirm the pump switches on, moves the water out, and shuts off cleanly.
- Before spring: repeat the test and clear any debris from the pit, since spring rain and thaw are when the pump works hardest.
- Once a year: a professional inspection of the pump, float, check valve, discharge line, backup system, and pit.
- Every few years: plan for eventual replacement. A hard-working pump is a wear item, and no pump lasts forever.
If your basement is finished, or your pump runs frequently, lean toward the more frequent end of every one of those intervals. A pump that cycles constantly simply wears faster than one that rarely runs.
Signs your sump pump may be failing
A sump pump usually gives warning before it quits for good. If you notice any of these, have it looked at — don’t wait for the next storm to find out the hard way:
- It runs constantly, or cycles on and off rapidly even when it isn’t especially wet — often a float or check-valve problem.
- Strange noises — grinding, rattling, or a loud hum — pointing to a worn or jammed motor or impeller.
- Visible rust, or water that looks or smells off, which can signal corroded parts or bacteria in the pit.
- Excessive vibration when running, which can mean a bent or damaged impeller.
- It doesn’t turn on during your test, or the float sticks and doesn’t rise with the water.
- It’s simply old — many pumps have been in the pit far longer than the homeowner realizes.
- The discharge line freezes, clogs, or dumps water right back toward the house — the pump may run fine and still leave you wet.
A battery backup sump pump protects you against the two failures a test can’t catch: a power outage during a storm, and a primary pump that dies at the worst moment. We check backups as part of every inspection.
What a Behncke sump pump inspection covers
Our professional inspection goes well beyond pouring in a bucket of water. We check the whole system, end to end:
- Test the primary pump and confirm it moves water and shuts off correctly
- Test float operation and check for sticking or obstruction
- Inspect the sump pit for debris, sediment, and condition
- Inspect the accessible check valve and discharge piping
- Test the battery backup system when present
- Inspect sump alarms when present
- Inspect the exterior discharge location and where the water actually ends up
- Look for clogged, disconnected, frozen, or poorly terminating discharge lines
This is the same sump-system check that’s built into our Annual Basement & Foundation Checkup — which also documents your foundation, waterproofing, drainage, and window wells and tracks them year over year. If your sump pump needs to be sized or replaced, see our Sump Pumps page.
