Sump Pump Repair Guys

Three usual causes. A float stuck in the raised position tells the pump the water is high when it is not, so it never gets the shutoff signal. A failed check valve lets discharged water fall back into the pit and refill it seconds after each cycle. Or the water table around your foundation is genuinely high and the pump is doing real work it was never sized for.

All three burn out motors quickly, because continuous running builds heat the pump cannot shed. A manual lift test and a backflow check separate them in a few minutes.

A hum with no flow almost always means the impeller is jammed or the motor bearings have seized. Debris pulled in from a basin that has never been cleaned is the usual culprit. It can also mean a completely blocked discharge line, where the pump is running against a closed pipe.

Switch it off. A humming motor under load is drawing current and heating up, and another hour of that turns a clearable jam into a replacement.

Pour several gallons of water slowly into the basin and watch a full cycle. The float should rise, the pump should start, the water should clear, and the pump should shut off on its own.

Then keep watching for thirty seconds. If water flows back into the pit, the check valve is failing. If the pump does not start at all, lift the float by hand: if it runs then, the problem is the switch, not the motor. Do this twice a year and before the wet season.

The working rule in the trade is to replace when the pump is past seven to ten years old, or when the repair estimate reaches about half the cost of a new unit installed. Below that line, repair usually wins.

A four year old cast iron pump with a dead float switch is worth repairing. A nine year old thermoplastic pump with a seized impeller is not. We show you which side of the line yours sits on and let you decide.

That is short-cycling, and it is one of the fastest ways to destroy a switch and a set of bearings. Three causes account for nearly all of it: a failed check valve dropping water back into the pit, a basin too small for the inflow, or float trip points set so close together that the on and off heights overlap.

None of those are fixed by buying a bigger pump, which is what most homeowners are sold. Correcting the actual cause is usually a parts-level job.

Seven to ten years for the pump itself, with quality cast iron units reaching the top of that band and budget thermoplastic ones often falling short of it.

Components vary more. Premium vertical float switches routinely last eight to twelve years, tethered floats five to eight, and budget switches can fail in two to four, often while the rest of the pump is still healthy. Backup batteries are the shortest lived at three to five years. The biggest lifespan killer across all of them is sediment in the basin.

Yes. A pump drawing enough current to trip a breaker has an electrical fault, a seized motor, or a jammed impeller forcing the motor to stall. That is a fire risk, not a nuisance.

Leave the breaker off and call rather than resetting it repeatedly. Every reset feeds current into a fault that is already failing.

Once a year for most basements, and more often if your groundwater carries heavy silt or iron ochre. Sediment grinds mechanical switches, jams impellers and narrows the float travel path until the switch stops working reliably.

Cleaning a basin is one of the cheapest things you can do for a sump system. Replacing a pump that died from grit is not.

Treat it as an emergency. The alarm means the basin is filling faster than the pump is clearing it, which is the last warning you get before water reaches the floor.

Check that the pump is plugged in and the breaker is on, then look at the pit and see whether the pump is running at all. Either way, something upstream has already failed. Call before you start bailing.

Usually not by default. Standard policies generally exclude groundwater intrusion and flooding caused by sump pump failure, and coverage for that specific event is normally sold as a separate rider or endorsement.

Check your policy language before you need it. A claim is a bad time to find out the answer.

Same day in most of our service areas, and after hours for emergencies where water is already coming in. Diagnosis on a standard system takes thirty to sixty minutes, and a parts-level repair such as a float switch or check valve is generally completed in the same visit.

The one thing worth knowing: during spring thaw and heavy autumn rain, every technician in your area is booked. An inspection before the season costs a fraction of an emergency call during it.
