A sump pump is one of those systems nobody thinks about until it fails during the exact storm it was installed to handle. We repair failing pumps, replace units at the end of their service life, and install battery backup systems for homes where a power outage during a storm would otherwise leave the basement unprotected.
Testing a sump pump before storm season, not during one, is the difference between a routine maintenance visit and an emergency call.

Eastern Prince William County's proximity to the Occoquan and Potomac rivers means a meaningful number of Woodbridge basements rely on their sump system more than homes further inland. The September 2011 flooding from the remnants of Tropical Storm Lee, which forced evacuations near Marumsco Plaza and swift-water rescues along Neabsco Road, is the extreme case, but it illustrates exactly the drainage pattern a sump pump is meant to handle on a smaller scale during any heavy, slow-moving storm.
Power outages tend to accompany the same storms that stress a sump pump hardest, which is why we specifically recommend battery backup systems for finished basements in this area rather than treating them as optional.
A battery backup's real-world runtime depends heavily on how often the primary pump would have cycled during that specific outage, not just the battery's rated capacity, which is why we talk through your pit's actual demand pattern rather than quoting a generic runtime number that may not reflect your situation.
Signs your sump pump needs attention.
- ✓Pump hasn't been tested in over a year
Pour a bucket of water into the pit; it should activate and drain smoothly. If it doesn't, don't wait for a storm to find out. - ✓Unusual grinding or rattling when it runs
Often a sign the impeller or motor bearings are wearing out. - ✓Pump runs constantly even in dry weather
Can indicate a stuck float switch or a high water table issue worth investigating. - ✓No battery backup on a finished basement
Power outages frequently accompany the storms that create the heaviest pump demand.
How we handle it
What to do the moment a sump pump fails during a storm: if the basement is actively taking on water, shut off electricity to that area at the breaker before stepping into any standing water, move anything valuable off the floor if it's safe to do so, and call. Don't attempt to service a pump that's still plugged in while the pit has water in it.
For a failing pump, we diagnose whether it's the float switch, the impeller, or the motor itself, and replace whichever component or the full unit makes sense given its age. We also check the discharge line for clogs or freezing risk, since a pump that runs but has nowhere for the water to go is functionally the same as a pump that doesn't run at all.
For battery backup installation, we size the backup system to your pit's typical demand and walk through the realistic runtime you can expect during an extended outage, rather than overselling capacity the system can't actually deliver.
We size any replacement pump to your pit's actual demand rather than defaulting to a one-size unit, and we test the full system, pump, float switch, check valve and discharge line, together, since a new pump draining into a clogged or frozen discharge line performs no better than the failed one it replaced.
For a new installation, we also check that the discharge line routes water far enough from the foundation to avoid it simply cycling back toward the same basement it's meant to protect, a detail that's easy to get wrong on a hurried DIY installation.
Primary and backup pumps get tested together as a system during any service visit, confirming the backup actually activates when the primary is manually disabled, not just that both pumps individually power on when tested in isolation.

How often should I test my sump pump?
At minimum once a year, ideally before the wetter months. Pour water into the pit and confirm the pump activates, drains fully, and shuts off cleanly.
Do I really need a battery backup?
If your basement is finished or holds anything you'd want to protect, yes. Power outages commonly occur during the same storms that push a sump pump hardest, which is exactly when you need it running.
Why does my sump pump run even when it hasn't rained?
Could be a stuck float switch causing false activation, or a genuinely high water table in your area feeding the pit even in dry weather. Both are worth diagnosing rather than ignoring.
