What to do when the basement is taking on water
Deal with electricity before you deal with the water. The CDC says to turn off power at the main breaker or fuse when circuits or electrical equipment are wet or near water. If reaching the panel means stepping into standing water, the CDC says to call an electrician to turn it off instead.
Never switch power on or off while standing in water. The CDC also warns against using any electric tool or appliance while standing in water, and that includes plugging in, unplugging or testing a sump pump.
Once you are out of danger, find where the water is coming in, because each source has a different fix:
- Water rising in the sump pit or seeping through the foundation wall or floor is groundwater or storm water, the job a sump pump does. Baltimore County’s basement seepage fact sheet, dated 2010 and still linked by the County in 2025, calls seepage a private property issue and suggests considering a sump pump when water seeps in at floor level.
- Sewage coming up through a basement floor drain is a sewer backup, not a sump pump problem. The Insurance Information Institute describes a blocked sewer main pushing sewage into homes through floor drains, and recommends a backwater valve, which lets sewage flow out but not back in, to prevent it. Follow the Baltimore checklist for sewage in the basement for reporting and safe cleanup. When backups keep returning from a cracked or root-filled lateral, the fix is repairing the private sewer pipe that serves your home.
- Water spraying or dripping from a pipe is a supply leak, not groundwater. Start with what to do first when a water pipe bursts indoors.
What are the signs a sump pump is failing?
A pump that runs nonstop, hums without moving water or shuts off early points to a specific fault. Pentair, a sump pump maker, ties nonstop running to heavy inflow or a stuck float switch, humming to a blocked intake, an air lock or a stuck check valve, and early shutoff to an overheated motor.
- Runs and never stops: Pentair says either more water than normal is coming in or the float switch is stuck in the on position, and that the float switch is typically the first thing to fail.
- Hums but moves no water: debris blocking the pump’s suction, an air lock, or a check valve stuck closed or installed incorrectly.
- Starts, then quits: the motor has overheated and been shut off by its thermal overload.
- Plugged into an extension cord or a shared circuit: Pentair calls electrical trouble probably the most common cause of sump pump failure, because the pump receives low voltage. It recommends plugging the pump directly into an outlet that is the only thing on its breaker.
- No backup when the power fails: NDSU Extension’s 2021 backup pump publication says lost utility power is the most common reason a sump pump stops, and that it often happens during the storms when the pump is needed most.
Can a sump pump drain into the sewer in Baltimore?
No, in either Baltimore City or Baltimore County. Baltimore City Code Article 25, § 2-3 bans discharging groundwater, stormwater, roof runoff or subsurface drainage into any sanitary sewer, and Baltimore County Code § 20-5-111(d) bars the same discharges into the County system. A pump piped into a floor drain, laundry sink or sewer line breaks both rules.
Baltimore City DPW tells residents to eliminate direct connections of sump pumps and roof leaders to the sanitary sewer, and its 2023 public Q&A lists sump pumps illegally connected to the sewer among the sources of overflows during storms. The Insurance Information Institute adds that debris and silt from these connections clog the line, and tells homeowners to have a plumber correct an existing illegal connection.
| Rule | Baltimore City | Baltimore County |
|---|---|---|
| Into the sanitary sewer | Prohibited (City Code Art. 25, § 2-3) | Prohibited (County Code § 20-5-111(d)) |
| Where the water may go | No City code section names sump pumps. The closest plumbing code rules send clear water to a storm drain where feasible, or by pipe to the street, alley or an approved water course, or onto the ground at least 10 feet from buildings and property lines without crossing a sidewalk or a neighbor’s lot. | Foundation drainage goes to a storm drain, street, alley, approved water course or ground level; at ground level, at least 10 feet from any property line where possible. |
| Civil penalty | At least $250 for each day the violation continues, plus damages | Up to $1,000 per violation for willful or repeated violations, with each day counted separately |
| Criminal penalty | Intentional violation: a misdemeanor with a fine of at least $250 a day, up to 6 months in jail, or both; up to 1 year for a repeat conviction | Willful violation: a fine of up to $1,000, up to 90 days in jail, or both |
Sources: Baltimore City Code, Article 25, §§ 2-3, 23-2 and 23-4; Baltimore City Building, Fire, and Related Codes, Part VI (Plumbing), §§ 314.2.1, 1105.3.3 and 1105.4; Baltimore County Code §§ 20-5-111(d), 20-5-127 and 20-5-129; Baltimore County Plumbing and Gasfitting Code, Chapter 11 (July 2024 edition).
Two more City rules apply. Connecting any building to a sanitary or storm sewer requires a DPW permit, and DPW may shut off and abandon an unauthorized connection at the owner’s expense. The plumbing code chapter the City adopts also lets one- and two-family homes send storm water onto lawns or streets, where approved, when it flows away from the building, and requires a check valve on the pump’s discharge piping, according to UpCodes’ reproduction of that code.
Does a sump pump need a battery backup?
A standard electric sump pump stops when the power goes out, often during the same storm that floods the basement. Ready.gov tells homeowners to consider a sump pump with a battery, and Baltimore County’s 2010 basement seepage fact sheet suggests a battery backup if your electricity goes out frequently.
A November 2024 urban flooding guide published by FEMA, written by a Cook County, Illinois, mitigation team, says ordinary sump pumps are not designed for large amounts of water and will not run without electricity unless you add battery storage or a generator. NDSU Extension adds that a backup pump also helps when the main pump’s motor burns out, its float switch fails, or water comes in faster than it can pump. Battery size decides how long a backup lasts in NDSU’s 2021 tests:
- 40 Ah battery, pumping nonstop
- Under 4 hours
- 120 Ah battery, pumping nonstop
- About 11 hours
- 75 Ah battery, cycling every 4 minutes
- 60+ hours
- Battery voltage check
- Every 6 months
How to test a sump pump and its backup
- Test the motor: Pentair says to unplug the float switch and plug the pump directly into the wall. It should run immediately; do not leave it plugged in for more than a few minutes, or it can overheat.
- Test the float switch: lift the float with a broom handle or similar non-conducting item, which Pentair recommends to avoid electric shock. The pump should start when the switch reaches its on level.
- Check the backup battery every six months: NDSU says a battery at rest should read 12.3 to more than 13 volts and should stay above 12.1 volts under load. Below 11.6 volts, consider replacing it.
- Choose a deep-cycle lead-acid battery, sometimes called a marine battery, which NDSU recommends for backup sump pumps.
- Add a high-water alarm and service the pump every year; the FEMA guide’s homeowner checklist asks about both, along with battery backup.
- For a long outage with someone at home, NDSU says a 1,500-watt generator can run the main pump and the battery charger.
In Baltimore County, a water-powered backup pump may only back up an electric pump, never replace it. The County plumbing code requires an ASSE 1013 reduced pressure principle backflow preventer on its water supply and does not allow vacuum breakers.
Repair or replace a sump pump: what it costs
HomeAdvisor (Jun 2026) puts a typical sump pump repair at $309 to $755 and a replacement at $645 to $2,120. A first-time installation with a new pit and an above-ground drainage line runs $800 to $2,000, according to Fixr (Jan 2025). The pump type, the part that failed and the extent of the damage set a repair bill.
| Repair or charge | Typical cost | What the range covers | Reported by |
|---|---|---|---|
| Repair of an existing sump pump | $309 to $755 | Repairing a sump pump; submersible pumps cost more to fix than pedestal pumps, and the part replaced and extent of damage matter. Emergency or after-hours calls cost more. | HomeAdvisor (Jun 2026) US national |
| Replacement pump, pit and discharge line already in place | $645 to $2,120 | Swapping out an existing sump pump where the pit and discharge line are already in place; pump type, location and local labor set the price. The source says totals can range from $280 to $4,800. | HomeAdvisor (Jun 2026) US national |
| New pump and pit where there was none | $800 to $2,000 | Installing a new submersible sump pump and pit with an above-ground drainage line. The source’s low end is $500 (a pedestal pump in an existing pit) and its high end $4,000 (a new pit with two pumps, underground drainage, battery backup and an alarm, drilled through a thick slab). | Fixr (Jan 2025) US national |
| New battery for an existing backup system | $250 to $500 | Replacing the battery in a battery backup sump pump system; batteries cannot be repaired and must be replaced. | HomeAdvisor (Jun 2026) US national |
| Backup battery added to a pump (unit only, not installed) | $150 to $250 | Price of adding a backup battery to an existing sump pump. The source lists it in its unit-only price section, so installation labor is not included. A pump with a built-in battery backup is listed at $150 to $2,000, also unit only. | Fixr (Jan 2025) US national |

Replacement estimates vary by publisher, and Fixr’s own January 2025 pages disagree with each other: its installation guide puts a replacement at $350 to $1,000, and its repair guide puts it at $700 to $1,600. The backup battery figure covers the battery alone, not installation, and we found no current published price for a fully installed battery backup system. Speedy Plumbing Baltimore finds what failed, prices the repair or replacement upfront, and starts work only after you approve it. The rate is the same at night, on weekends and on holidays.
Does homeowners insurance cover a flooded basement from a failed sump pump?
Usually only with a water/sewer back-up endorsement. The Maryland Insurance Administration says water that overflows a sump pump may be covered if you bought that endorsement, which Maryland law requires insurers to offer for an extra premium. Groundwater that seeps through a foundation wall or floor is generally covered by neither homeowners nor flood insurance.
| Where the water came from | What may cover it | Source |
|---|---|---|
| Water overflowing a sump pump | A water/sewer back-up endorsement bought for a homeowners policy | Maryland Insurance Administration |
| Groundwater seeping through a foundation wall or floor | Generally neither homeowners nor flood insurance; seepage is treated as a maintenance issue | Maryland Insurance Administration |
| Sewage backing up through drains | Not a typical homeowners or flood policy; a separate product or an endorsement | Insurance Information Institute |
| Flooding | Not homeowners insurance; a flood policy, which typically takes up to 30 days to go into effect | Ready.gov |
Is there help paying for sump pump work in Baltimore?
We found no Baltimore City or Baltimore County rebate or grant aimed at sump pumps or battery backups. The closest help is income-based home repair loans: both governments lend eligible homeowners money for repairs that include plumbing, and some Baltimore City loans can be forgiven or deferred.
- Baltimore City: the Department of Housing and Community Development offers repair loans for eligible owner-occupied homes, with plumbing among the systems covered; its grants are for lead and accessibility work. Income limits are $74,800 for one person and $106,800 for a household of four. Call the LIGHT Intake & Assessment Unit at (410) 396-3023.
- Baltimore County: housing rehabilitation loans for households earning up to 80% of area median income cover major systems, including plumbing, and the work must be done by a licensed, insured contractor. The State-funded MHRP loan carries 0% to 6% interest over 20 years, as described on the County’s loan program page in September 2025.

Sump pump questions
Can a sump pump drain into the sewer in Baltimore?
No. Baltimore City Code bans discharging groundwater, stormwater or subsurface drainage into any sanitary sewer, and Baltimore County Code bars the same discharges into the County system. A City violation carries a civil penalty of at least $250 for each day it continues, and County fines for willful or repeated violations reach $1,000 per violation.
How much does sump pump repair cost?
HomeAdvisor (Jun 2026) puts a typical sump pump repair at $309 to $755 and a replacement at $645 to $2,120. Fixr (Jan 2025) puts a new pump and pit, where there was none, at $800 to $2,000. These are national market ranges, and the pump type and the part that failed set the final price.
Why does my sump pump keep running?
Pentair, a sump pump maker, says a pump that runs nonstop either has more water coming in than normal or has a float switch stuck in the on position. It also says the float switch is typically the first part to fail.
How long does a sump pump battery backup last?
It depends on the battery size and how often the pump runs. In NDSU Extension tests published in 2021, a 40 amp-hour battery gave less than 4 hours of nonstop pumping and a 120 amp-hour battery about 11 hours, while a 75 amp-hour battery lasted at least 60 hours with the pump cycling every four minutes. NDSU recommends checking the battery voltage every six months.
Does homeowners insurance cover water from a failed sump pump?
Usually only with a water/sewer back-up endorsement. The Maryland Insurance Administration says water that overflows a sump pump may be covered if you bought that endorsement, which Maryland law requires insurers to offer for an extra premium. Groundwater seeping through a foundation wall or floor is generally covered by neither homeowners nor flood insurance.
Is a flooded basement from a sump pump failure the same as a sewage backup?
No. A failed sump pump lets groundwater or storm water collect in the basement, while a sewage backup comes up through a floor drain from a blocked or overloaded sewer. The CDC advises rubber boots, rubber gloves and goggles when sewage is involved, and the repair is on the sewer line, not the pump.
