A sump pump fails in a wet spring because the clay till around the house sheds water slowly, so the footing drains keep filling the pit faster than the pump can empty it. Power loss, a frozen discharge line or a worn pump can stop it altogether. Stay out of standing water near outlets, the furnace or the panel, and photograph the damage before anything is moved.
Key takeaways
- Clay till in Cuyahoga County sheds water instead of absorbing it, so the footing drains can keep feeding the pit for weeks in a wet spring.
- A pump that runs nonstop is often doing its job, and the problem starts when the pit fills faster than the pump can empty it.
- Power loss, a frozen discharge line and a stuck float are common reasons a sump stops working during a storm.
- The first hour matters most: stay out of standing water near electrical equipment and photograph everything before moving it.
- Water that comes up through a floor drain from the sewer is a different job from water that rises out of the pit, and it is treated as contaminated.
- Sewer and drain backup is usually an add-on endorsement to a homeowners policy, so check your coverage before you need it.
Why does the sump pump run nonstop in a wet spring?
The pump usually runs for long stretches because water is reaching the pit faster than it does in drier months. The footing drains and the groundwater around the house keep delivering into the pit, and the pump cycles to keep up.
A sump pit sits at the lowest point of a basement, often in a corner or near the middle of the floor. The footing drains around the foundation carry groundwater to that pit, and a float switch starts the pump when the water reaches a set height. In a wet March or April the pit can refill quickly, so the pump may run for hours without a break. That is the system working as designed, though it is also the period when a pump is most likely to give out.
Many Lakewood basements are older, with stone, rubble or early concrete walls and commonly no drain tile, so the pump may be the only thing keeping the floor dry. Newer poured walls with a sump pit are the norm in the newer suburbs. Either way, a pump that runs for days straight is a reason to check it and plan for the next storm, not a reason to ignore it.
What makes the ground here hold water?
Much of Cuyahoga County sits on glacial till, a slow-draining clay that sheds water instead of soaking it up. In a wet spring the ground can stay saturated for weeks after the rain stops.
The USDA soil series that cover this part of the county, including Mahoning and Ellsworth, are slow-draining. The Mahoning series is described as somewhat poorly drained and Ellsworth as moderately well drained, so rain that lands on the yard tends to run off or sit near the surface instead of moving down quickly. That shedding behavior is the reason the footing drains keep running after a storm has passed.
Lots here are narrow, often 30 to 40 feet wide, with little ground left to absorb rain. Downspouts that discharge a few feet from the wall add water right where the foundation needs it least. A neighbor's grading can send water toward your wall, so the source is not always inside your own property line. Clearing downspouts and extending them away from the house is one of the few steps most owners can take before a storm.
What causes a sump pump to stop working?
Most failures come down to four things: no power, a blocked or frozen discharge line, a float that does not rise and fall freely, or a pump worn out after years of running. Each one looks different once you are standing in the basement.
Power loss is the one that catches people. Storms that knock out electricity also take out the pump, and without a backup the pit fills and water rises into the basement. A pump that hums but does not move water usually has a blocked intake or a discharge line that is no longer flowing.
In cold weather the discharge line is the weak point. Water leaving the pit travels through a pipe that runs outside, and in a hard freeze that pipe can ice shut, so the pump keeps pushing against a blockage. A float that sticks against the pit wall, or a pump that has simply run too many years, are the other common causes. A plumber can check each of these, so none of them needs a guess.
What should I do in the first hour?
Stay out of standing water near outlets, the furnace or the electrical panel, and shut off the water at the main if a supply line is also involved. Then photograph the damage before anything is moved.
Water on a basement floor becomes a shock risk once it reaches electrical equipment, so do not wade through it to reach the panel. Keep children and pets out of the basement until the water is gone and the area has been checked. If the water is nowhere near electricity and you can reach the panel dry, you can make that call yourself, but most people in this situation should leave the panel alone.
Next, stop the water if you can do it safely, for example by closing the supply valve if a line has burst. Take photos and video of the pit, the discharge line, the water line on the walls and the floor. Calling is the next step, since the phone is answered 24/7 at (833) 490-5225 and a crew is dispatched as fast as one is available. The crew can help stop the water at the shut-off, set drying equipment and document moisture readings, and you can read more on the service page for sump pump failure cleanup.
Does a battery backup or a second pump help?
A battery backup or a second pump can keep the pit emptying during an outage, but the choice and the installation belong to a plumber. This site does not sell or install pumps.
Power loss is the failure most people plan for, and a battery backup is one answer. Whether it fits your pit, your discharge line and your electrical setup is a question for a licensed plumber. Plumbing work is licensed in Ohio. The state board licenses commercial plumbing contractors, and city building departments handle residential registration, so ask any company which license it holds and check it with the issuing office.
Restoration is a different job. Once water is on the floor, the crew's work is extraction, drying and moisture monitoring until materials are dry, and repairs after drying are quoted separately once someone has seen the wet area. The price for the emergency stage is explained and approved before work starts, and nobody can price it honestly over the phone.
How is a sump failure different from a sewer backup?
A sump failure brings groundwater up out of the pit. A sewer backup comes up through the floor drain from the sewer side. In Lakewood the sewer side is a combined system that can overflow in heavy rain, which is why the two are often confused.
Lakewood runs a combined sewer system, which carries sanitary sewage and storm water in one pipe. The U.S. EPA settlement with the city describes untreated discharges from that system, and the city publishes an overflow event map that shows when wet-weather overflows happen. When a basement floor drain backs up, the water has come from the sewer, not the pit, and it should be treated as contaminated.
Groundwater from a sump pit is not sewage, but it still needs prompt drying and cleaning, and any removal of carpet, pad or drywall depends on what the water was and how long it sat. Keep the two sources in mind when you talk to the crew, and ask on site which water category it is treating the water as. Sewer and drain backup is usually an add-on endorsement to a homeowners policy, not part of the base policy.
What should I document for my insurer?
Take photos before anything is moved, record the pump's condition and the water line on the walls, and list damaged belongings. Coverage is decided by your insurer under your own policy, not by the crew.
Insurers want to see the damage in its original state. Photograph the pit, the pump, the discharge line, the water line on the walls and the floor, and every belonging before you move it. Video works well for this. Write down when you first saw water and when the power went out or the pump stopped, because those times help explain the loss.
Check your policy for sump pump and sewer backup coverage, and ask your agent what it includes. The crew can give you moisture readings and photos for your claim and can document the damage, but whether the loss is covered is your insurer's decision.

Frequently asked questions
Is a sump pump that runs for hours an emergency?
A pump that runs for long stretches during a wet spring is usually reacting to high groundwater rather than failing. It is still worth watching closely, especially if the pit is filling faster than the pump can empty it or water has reached the floor. If water is on the basement floor, treat it as urgent and call for a crew, since the phone is answered 24/7 and a crew is dispatched as fast as one is available.
Can I clean up the water myself?
You can move belongings off the floor and keep the area ventilated, but standing water near electrical equipment is not safe to wade through. Drying is a matter of moving air and monitoring moisture until materials reach dry readings, which is what the crew does with meters and thermal imaging. Mold can trigger allergy and asthma symptoms in some people, and drying speed limits that risk. Ohio does not license mold remediation the way some states do, so ask any company what guidance it follows, such as the ANSI/IICRC S520 standard and EPA mold guidance.
Why did my pump fail during last night's rain?
Heavy rain fills the pit faster, so a pump with a weak float, a blocked intake or a failing motor shows its problem first. Power loss from storms is a common cause, and a pump with no backup stops entirely when the power goes. After the storm, check the discharge line and the float, and ask a plumber to look at the pump itself. Restoration starts once the water is out of the basement and the area is safe to enter.
Does my homeowners policy cover sump pump failure?
Coverage depends on your policy and the cause of the loss, and this page cannot say what your policy does. A standard homeowners policy generally responds to sudden and accidental water damage, while sewer and drain backup usually needs an added endorsement. Flood, meaning surface water, rivers and creeks, is a separate policy. Read your declarations page and ask your agent before you assume either way.
Do I need a plumber or a restoration crew first?
Often you need both, in that order or at the same time. A plumber repairs or replaces the pump, the float, the discharge line or any backup system. A restoration crew handles the water on the floor, the drying and the cleanup. Plumbing repair is not part of the work offered through this site, so ask any company which registration it holds in the city where your house is, and check with that city's building department.
Will the crew remove or replace the pump?
The crew's work is the water damage after a failure, not selling or installing pumps. Removing a failed pump and fitting a replacement is a plumbing task. The crew can help with the cleanup around the pit and document the damage for your claim. Ask your plumber what your pit needs before any replacement is chosen.
