Emergency sump pump repair in Marblehead, MA
A sump pump that stops during heavy rain leaves the basement to the groundwater, and our line is answered 24/7. Check that the pump is plugged in and that the breaker has not tripped, keep electronics off the floor and call. Same-day visits are offered when a slot is available.
Sump pump repair means diagnosing why the pump will not start, will not stop or will not move water, then fixing or replacing the part that failed. Typical causes are a stuck float switch, a tripped breaker, a clogged intake screen, a failed check valve or a motor at the end of its life.

Groundwater on a coastal peninsula
Marblehead is a rocky coastal peninsula, with ledge close to the surface and the harbor and ocean around it. Low-lying lots near the water and homes at the foot of a slope see the most groundwater, and basements in those spots are the first to take in water when the rain comes hard.
A pit in ledge can be hard to dig, and some basements simply have no practical place for one. We look at the floor, the walls and the drainage path before recommending a pump, and we tell you if a different approach fits the house.
Why a sump pump fails when it is needed most
Pumps sit idle for weeks and then work hard in a storm. A float that sticks against the pit wall, a motor that seized from lack of use or a switch that corroded can all fail at the first heavy rain. That is why running the pump by hand with a bucket of water, a few times a year, is worth the minute it takes.
Power outages often arrive with storms. A pump without a battery backup stops when the power does, which is the most common reason a basement floods even when the pump is working.
Pump runs but water does not move
If the motor hums but the pit does not empty, the impeller may be clogged with grit, or the check valve may have stuck. The check valve stops water from draining back into the pit once the pump shuts off, and a failed one makes the pump cycle constantly.
A discharge line that is frozen or blocked outdoors will also stop flow. We check the full path from the pit to where the water leaves the property.
Sump pump not working?
Call the 24/7 line before the water rises.
Pump that never shuts off
Float stuck up
The switch never signals the pump to stop.
Failed check valve
Water falls back and restarts the pump repeatedly.
High groundwater
A heavy storm or tidal influence keeps the pit full.
Undersized pump
A small pump may run constantly under heavy inflow.
Battery backup and water-powered backup
A battery backup pump takes over when power fails or the main pump jams. A water-powered backup uses municipal pressure to push water out and needs no electricity, but requires a plumbing connection and a drain path. We explain each option and what it needs.
Backup systems need their own testing. A battery that is not maintained will not work when called on.
What to check before you call
- Is the pump plugged in and the outlet working?
- Has the breaker or a GFCI tripped?
- Is the float free to move up and down?
- Is the discharge line outdoors frozen or blocked?
Sump pump faults and fixes
Most failures trace to one of a few parts, and the repair depends on which.
| Fault | Likely cause | Usual fix |
|---|---|---|
| Pump will not start | Tripped breaker, stuck float, dead motor | Reset, free the float or replace the pump |
| Pump runs constantly | Failed check valve or stuck float | Replace the valve or switch |
| Pump hums but moves no water | Clogged impeller or blocked line | Clean the impeller, clear the line |
| Pump fails in outages | No backup power | Add a battery or water-powered backup |
What affects the price of sump pump work
The price depends on the pump and the pit. We confirm it before work starts.
Standard homeowners policies often exclude flooding from groundwater or a failed sump pump unless a water backup endorsement was added. Check yours before a storm, not after.
Sump pump questions
Yes. The line is answered 24/7 and same-day visits are offered when available.
Most pumps last about 7 to 10 years, less with heavy use. Test yours a few times a year.
If your basement floods when the power goes out, yes. A backup is cheaper than the damage it prevents.
A failed check valve, high groundwater or a stuck float can do it. The plumber finds which.
Often yes, if the basement has a spot to dig a pit and a path for discharge. See basement waterproofing.
Generally no. Many towns prohibit tying a sump to the sanitary sewer. Ask the Marblehead Water and Sewer Department.
