When a failed sump pump is an emergency
A sump pump failure is urgent when water is arriving faster than you can hold it back. These are the signs.
- Water is rising in the sump pit and the pump is silent, humming without moving water or running without stopping.
- A storm is under way or forecast, and the pump has not cycled even though the pit is full.
- The basement floor is wet or water is entering at the wall joint, and the pit is not draining.
- The power is out and you have no battery backup. A pump that cannot run will not protect you.
- You smell sewage or see a dark color in the pit, which can mean a different problem such as a backed-up line.
Do not walk into standing water if the panel, a furnace or a water heater is nearby. Shut off power at the panel only if you can reach it over dry floor. If water is deep, call us and your electric utility rather than going in.
Why a sump pump matters on this coast
Wareham sits at the head of Buzzards Bay, and the NWS notes that Hurricane Bob in 1991 drove surges of 12 to 15 feet at Onset, Wareham and Bourne. Wareham has four named rivers, including the Wareham and Weweantic, plus long stretches of shoreline. Low lots near the water and along the rivers are where a basement is most likely to see groundwater.
Storms also knock out power, and that is when a plain electric pump stops. During that same storm, more than 60 percent of residents in southeastern Massachusetts and Rhode Island lost power. A pump with a battery backup keeps running when the grid does not.
Common ways a sump pump fails
Most failures are one of these. A plumber can usually tell which from the sound and the pit.
Stuck float switch
The float arm jams on the side of the pit or the tether tangles, so the pump never turns on. This is the most common cause of a dry-running pump.
Burned-out motor
Constant cycling in wet weather, or a pump past its service life, wears the motor out. Humming without pumping is the usual sign.
Failed check valve
Water flows back into the pit after each cycle, so the pump cycles again and again. You hear a thud as water falls back.
Clogged intake or frozen discharge
Silt and gravel plug the intake. In winter, standing water in the discharge line can freeze and block it.
No power
A tripped breaker or outage stops the pump. A battery backup or water-powered backup covers this.
How we repair or replace a sump pump
The job is usually done in one visit once the cause is found.
- 1
Check the pit and power
We confirm power, test the float and look for debris or a collapsed pit liner.
- 2
Find the failure
We run the pump with water and watch the float, the motor and the discharge. A check valve is inspected for backflow.
- 3
Fix or replace
A stuck float or a bad check valve is repaired. If the motor is dead or the pump is old, replacing the pump is the sounder choice.
- 4
Test and explain
We fill the pit to confirm the pump cycles, then show you how to test it and what a backup adds.
Water rising in the pit?
Call the 24/7 line. A dispatcher books the next open licensed plumber for your address.
Storm coming and the pump is dead?
Call before the rain arrives. After-hours and weekend requests reach the same dispatcher.
Pump parts, problems and fixes
This table covers the parts that matter. Your pump may show more than one problem at once.
| Part | What goes wrong | What we do |
|---|---|---|
| Float switch | Jams, tangles or sticks on, so the pump never starts or never stops | Untangle, reposition or replace the switch |
| Check valve | Cracks or sticks, letting water fall back into the pit | Replace the valve in the discharge line |
| Discharge line | Freezes, clogs or drains toward the house | Clear, re-slope or reroute the line |
| Motor | Burns out from age or heavy cycling | Replace the pump |
| Battery backup | Dead battery or tripped unit | Test, replace the battery or the unit |
Battery backup and the discharge line
A battery backup pump sits beside the main pump in the pit and runs from a sealed deep-cycle battery when the power fails. It is a second pump, not a spare part, and it needs a battery test every so often. We install and test them.
The discharge line carries water away from the foundation. If it dumps close to the house or runs level, the water can flow back toward the foundation and the pump recycles the same water. A line that runs uphill or ends too near the wall needs rerouting, and an exterior outlet should be set so winter ice does not seal it.
Sump pumps, drains and the town sewer
A sump pump should discharge outdoors. Tying it into a sanitary drain sends clean groundwater into the sewer or septic system, which is a bad use of both. Wareham's Sewer Department runs about 61 miles of gravity pipe and 45 pump stations, so ask the department if you are unsure how your house is connected.
If a basement keeps wetting and no pit exists, a pump alone may not fix it. We explain what we see, and whether a perimeter drain or leak detection is the better next step.
What affects the price of sump pump work
The price is clear before work starts. These are the factors.
Many homeowners policies exclude water that comes up through the floor or from a failed pump unless a specific endorsement is added. Ask your insurer, and photograph the pit and the pump.

Frequently asked questions
Yes. The line is answered 24/7, including storm nights, weekends and holidays. Tell the dispatcher that the pump has failed or the pit is rising, and the next open licensed plumber is booked. Same-day appointments are offered when a slot is available.
The pit fills but the pump does not start, it hums without moving water, or it runs nonstop. Test it by pouring a bucket of water into the pit. If it does not turn on, call.
It depends on how often it cycles, but most need replacement after several years of regular service. A pump that runs constantly wears out faster. We check the motor and float during a visit.
If your basement floods when the power is out, yes. Storms and outages often arrive together, and a standard pump stops with the grid. A battery backup pump keeps the pit emptying.
It stops the water in the discharge line from falling back into the pit when the pump shuts off. A failed valve makes the pump cycle more than it should and shortens its life.
Outdoors, away from the foundation and on ground that slopes away. It should not go into the sanitary sewer or the septic system, because that overloads it. Ask us about your yard.
Permit rules vary with the work, so ask Wareham's Inspectional Services office at Memorial Town Hall about yours. Under 248 CMR 3.05, plumbing permits are issued only to licensed individuals, and simply clearing a stoppage does not need one.
