How Sump Pump Repair goes, from cleanout to final pass
A pump that hums without moving water usually has a jammed impeller, an air lock or a motor on its way out. Gravel and silt drawn off the pit floor jam the impeller. An air lock forms when air trapped between the pump and the check valve can’t escape, and a small weep hole drilled in the discharge pipe below the check valve cures it.
Short cycling, the pump switching on every minute or two in dry weather, usually points at a failed check valve letting the discharge water fall back into the pit, or a float set with too little travel. Every start wears the switch and the motor, so fixing it adds years to the pump.
A pump that never shuts off has either a stuck float switch or more inflow than it can handle. A float caught against the pit wall or its own power cord is a quick fix. If the pump is working correctly and still losing ground, the problem is capacity, and that moves the job to replacement.
We tell you when a repair isn’t worth it. A pump whose motor draws high current, whose housing is cracked, or that has already overheated once gets condemned, and we say so plainly instead of fitting a new switch to a pump near the end of its life.

FAQ
Sump Pump Repair: what people ask first
Why is my sump pump humming but not pumping water?
Usually a jammed impeller, an air lock or a failing motor. Debris drawn up from the pit floor can jam the impeller, and air trapped between the pump and the check valve can keep it from moving water; a small weep hole in the discharge pipe lets that air out. If neither is the cause, the motor is likely on its way out.
Why does my sump pump turn on every few minutes in dry weather?
Most often the check valve has failed, and the water in the discharge pipe falls back into the pit each time the pump stops, refilling it. A float set with too little travel or a pit that is too small can do the same. Short cycling wears out the switch and motor, so it is worth fixing even while the basement stays dry.
Is it worth repairing a sump pump?
It is when the fault is a part outside the motor: a float switch, a check valve, a clogged intake or an air lock. Those repairs cost far less than a new pump. When the motor is failing, the housing is cracked or the pump is near the end of its life, replacement is the better use of the money.
What makes a sump pump suddenly stop working?
Most sudden failures come down to power or a stuck float: a tripped breaker or GFCI, an unplugged cord, or a float caught on the pit wall or the power cord. Check those first. If the power is good and the float moves freely, the switch or the motor has failed, and a high-water alarm would have warned you in time.
