Sump Pump Failed and the Basement Is Flooding: What to Do
The sump pump stopped running, the pit is overflowing and water is spreading across the basement floor. Here is what it usually means, whether it is an emergency and what to do now. One call connects you with a local crew, any hour.
When a sump pump fails, groundwater keeps filling the pit and spills onto the floor, and in a storm it can rise fast. The usual causes are a power outage, a stuck float switch or a worn out pump. Keep away from water near outlets, move belongings up, and call (203) 555-0163 to reach a local crew that can pump out the basement and start drying.
The Usual Causes
- Most common
Power outage
If the lights are out or a breaker tripped, the pump simply has no power. This is the most common reason pumps stop during big storms, and only a battery or generator backup keeps it running.
- Cause 2
Stuck or tangled float switch
If there is power but the pump is silent while the pit fills, the float that tells it to turn on may be jammed against the pit wall or snagged on the cord.
- Cause 3
Pump running but losing ground
If you hear the pump running nonstop while water still rises, it may be too small for the inflow, worn out, or pushing water through a clogged or frozen discharge line.
- Cause 4
Burned out motor
A humming pump that moves no water, or one that clicks and stops, has likely failed mechanically. Older pumps that have run hard through many seasons are the ones that quit.
Is It an Emergency?
Call now if
- Call now if water is near outlets, the furnace, the water heater or the electrical panel.
- Call now if the water is rising and the pump is not keeping up.
- Call now if a finished basement, carpet or drywall is already wet.
- Call now if the power is out and more rain is forecast.

It can usually wait a few hours if
- It can usually wait a few hours if the pump is running again and the water is going down.
- It can usually wait a few hours if only a small wet ring surrounds the pit.
- It can usually wait a few hours if the basement is bare concrete with nothing stored on the floor.
- It can usually wait a few hours if the rain has stopped and groundwater is falling.
Still call today: hidden moisture keeps spreading while it waits.
What to Do Right Now
- 1Do not wade near power If water is spreading toward outlets or the panel, stay out of it. Only shut off basement circuits if the panel is in a dry spot you can reach safely.
- 2Check the power first Look for a tripped breaker or an unplugged cord, if you can reach them without standing in water. Many pumps stop simply because power was cut.
- 3Unstick the float if it is safe With the pump unplugged and your hands dry, look into the pit. If the float is wedged against the wall, loosening it can restart the pump.
- 4Move belongings up Get boxes, rugs, electronics and furniture off the floor and away from the pit, starting with things that soak up water.
- 5Check the discharge outside In winter, see if the discharge line outside is frozen or buried in snow, which stops water from leaving even when the pump runs.
- 6Call a plumber for the pump A dead pump needs repair or replacement, while the wet basement needs a restoration crew. Both calls can happen at the same time.
How a Crew Finds the Source and Fixes It
A crew first deals with the water still coming in. If the pump is dead, they bring portable pumps to lower the pit and the floor water, which buys time while a plumber replaces the sump pump. They check whether anything else is adding water, such as a floor drain backup or a leaking water heater, since a flooded basement often has more than one source. Moisture meters and thermal imaging then show how far water spread under flooring and into the bottom of finished walls. They also look at the furnace, water heater and washer bases, since appliances that sat in water may need a service check before they run again.
Drying follows the same path as any clean-water basement flood. Standing water is extracted, wet carpet pad is removed, and drywall is cut a short way above the highest wet reading. Dehumidifiers and air movers run for several days while the crew takes daily readings. If the water mixed with a drain backup, porous materials it touched are removed and surfaces are disinfected. Boxes and stored items that soaked up water are moved out so the floor can dry. Once the new pump is in, the crew confirms it is cycling properly before pulling their own pumps, so the basement does not refill overnight while drying equipment is still running.
- 1
Lower the water fast
Portable pumps take over for the failed sump pump, pulling water out of the pit and off the floor so damage stops spreading while repairs are arranged.
- 2
Check for other sources
The crew looks for a floor drain backup, water heater leak or wall seepage, since a basement that floods during a storm often has more than one cause.
- 3
Extract and remove
Remaining water is extracted from carpet and concrete, and soaked pad, insulation and the bottom of wet drywall are removed so hidden spaces can dry properly.
- 4
Set up drying
Dehumidifiers and air movers are placed through the basement, and the crew checks moisture readings each day until floors, framing and walls are back to normal.
- 5
Restore the space
After drying is confirmed, drywall, baseboard and flooring are put back, and you are reminded to have the new pump and a backup system tested.
How to Keep It From Happening Again
- Add backup power. A battery backup pump or a generator keeps water moving when storms knock out power, which is exactly when the pump is needed most.
- Test the pump each season. Before spring thaw and before hurricane season, pour a bucket of water into the pit and make sure the pump starts, runs and shuts off.
- Keep the pit clean. Clear out silt, gravel and debris so the float moves easily and the intake does not clog during a heavy inflow.
- Protect the discharge line. Make sure the outside discharge points away from the house and is not buried in snow or frozen in winter.
- Replace an aging pump early. A pump that has run hard for many seasons is cheaper to replace on your schedule than during a flooded basement in a storm.
What It Costs
Pumping out and drying a clean-water basement typically costs $3 to $7.50 per sq ft, and a finished basement flood cleanup ranges from $3,000 to $15,000. Replacing the sump pump itself is plumber work, usually $600 to $2,000, and drying equipment runs $60 to $150 per dehumidifier per day. General market ranges, not quotes.
How Long It Takes
Once the water is out, an unfinished basement usually dries in two to four days. A finished basement needs about three to five days of drying, then one to two weeks for drywall, trim and flooring.
Call (203) 555-0163Sump Pump Failed and the Basement Is Flooding in Connecticut
Sump pumps work hardest in Connecticut when snowmelt and heavy rain raise groundwater, and they fail at the worst moment when storms cut power. Tropical Storm Irene in 2011 left over half the state without power, and every pump without a backup stopped with it. In Litchfield County, Norfolk averages about 74.9 inches of snow a year, so spring melt keeps pits busy for weeks. Middlesex County has many rural towns with private wells, where the basement also holds a pressure tank. In Windham County, West Thompson Lake averages 50.1 inches of precipitation and about 38.5 inches of snow a year.
Call (203) 555-0163 and tell us the pump stopped and how deep the water is. We connect you with a local restoration pro in your area, and crews are dispatched quickly with pumps and drying equipment. If the power is still out, say so, since the crew may need to bring its own generator to run pumps and dehumidifiers until service is restored. Calls only, no forms.
Sump Pump Failed and the Basement Is Flooding FAQs
What do I do when my sump pump stops working?
Stay away from water near electrical gear, check whether the power or breaker is off, and see if the float is stuck. If the pump will not restart, call a plumber for the pump and a restoration crew for the water.
Why did my sump pump fail during a storm?
Most failures during storms come from power outages, since a pump without battery or generator backup stops when the power goes. Stuck floats, clogged intakes and worn out motors are the other common causes.
How fast can a basement flood when the sump pump fails?
It depends on how much groundwater is coming in. During heavy rain or snowmelt a full pit can overflow quickly and keep spilling until the pump is running or water is pumped out another way.
Can carpet be saved after a sump pump failure?
Carpet soaked with clean groundwater can sometimes be dried in place, but the pad underneath usually has to be replaced. If the water mixed with a drain backup, the carpet should be removed.
How much does a sump pump failure cleanup cost?
Drying usually runs $3 to $7.50 per sq ft, and finished basement cleanups range from $3,000 to $15,000. A new sump pump installed by a plumber generally costs $600 to $2,000.
