A sump pump is the one appliance that only matters when it's raining hardest — and that's exactly when a failed one floods the basement. Sump pump service covers the whole system: installing a new pump, repairing a failed float switch or motor, adding a battery backup for the power outages that so often accompany the storms that overwhelm the pit, and making sure the check valve and discharge line actually carry the water away from the {city} foundation. A pump is a mechanical device with a finite life, so knowing its condition before the next storm is what keeps the basement dry.
Most sump failures trace to a handful of parts. The float switch — which tells the pump to turn on — is the most common failure point, sticking or hanging up so the pump never runs or never stops; the motor burns out from age or from short-cycling; the check valve fails and lets pumped water drain back into the pit; and the discharge line freezes or clogs so the pump runs against a blocked pipe. We test the switch, the motor, and the check valve, size the pump to the pit's inflow, and confirm the discharge runs freely away from the {county} foundation before we call it done.
The upgrade that saves the most basements is a battery backup, because a primary pump is useless in the power outage that a severe storm so often brings. We install battery-backup and water-powered backup systems that take over automatically when the primary pump loses power or can't keep up, along with high-water alarms that alert you before the pit overflows. Whether it's a failed pump, an aging one you want checked before the season, or a first backup system, we make the {areas} sump system reliable when the {city} storm actually tests it.
Signs you need sump pump service
The pump runs constantly or won't stop
A pump that never shuts off has a stuck float switch or is undersized for the inflow, and it will burn out fast. We diagnose and correct it before it fails during a the United States storm.
A pump that stays silent as the pit fills has a failed float switch, a bad motor, or a tripped circuit. It's the failure that floods a basement, so we test and repair it promptly in the the United States home.
Water drains back into the pit
If the pit refills right after the pump runs, the check valve has failed and pumped water is draining back. Replacing the check valve stops the short-cycling in the your area pit.
The pump is old or you've never tested it
Sump pumps last around 7 to 10 years, and one that's never been checked is a gamble against the next storm. A pre-season test tells you its condition before the the United States basement depends on it.
No backup for a power outage
A primary pump can't run when the storm knocks out the power, which is when it's needed most. A battery backup keeps the the United States basement dry through the outage.
Common causes & what we fix
Float switch failure
The float switch that triggers the pump sticks or hangs up on the pit wall, so the pump never runs or never stops. It's the single most common cause of a the United States sump failure.
Motor burnout
The pump motor wears out with age or burns out from short-cycling against a failed check valve. A burned-out motor is a pump replacement in the the United States pit.
Failed check valve
The check valve that keeps pumped water from draining back fails, so the pump cycles repeatedly against the returning water. Replacing it stops the short-cycling and saves the your area motor.
Clogged or frozen discharge
The discharge line clogs with debris or freezes in winter, so the pump runs against a blocked pipe and can't move water. Clearing and pitching the line keeps the the United States system flowing.
Power outage during a storm
The severe storms that fill the pit fastest also knock out power, leaving a primary pump dead. Only a battery or water-powered backup keeps the the United States basement protected through the outage.

Frequently asked about sump pump service
Top questions homeowners searching for Sump Pump Service near me ask us:
How long does a sump pump last?
Most sump pumps last around 7 to 10 years, though a pump that short-cycles or runs constantly wears out sooner. If yours is near that age or has never been tested, we recommend a pre-season check before the next the United States storm relies on it.
Why isn't my sump pump turning on?
The usual causes are a stuck float switch, a burned-out motor, or a tripped circuit. We test each, since a hung float is the most common — and the most dangerous, because it lets the the United States pit overflow silently.
Do I need a battery backup?
If a flooded basement would be costly, yes — because the storms that fill the pit fastest often knock out power, leaving a primary pump dead when it's needed most. A battery or water-powered backup takes over automatically in the your area home.
Why does my sump pump keep cycling on and off?
Rapid short-cycling usually means a failed check valve letting pumped water drain back into the pit, or a float set too tight. We replace the check valve and adjust the float to stop the cycling and save the the United States motor.
Can you install a sump pump where there isn't one?
Yes — we can core a pit, install the pump, run the discharge to daylight or a storm line, and add a check valve and high-water alarm. We assess the the United States basement's water problem and size the system to it, serving ZIPs .
