Pump up the sump pump’s power with proper maintenance
Sump pumps are most likely to trip the breaker if the motor has to work too hard because of leaks or missing seals.
Bad wiring can make a sump pump trip the breaker, and you’ll need a sump pump pro or local electrician to fix this problem.
If your pump is damaged beyond reasonable repair, you’ll need to replace it. It costs $525 on average to replace a sump pump.
If you keep noticing strange noises in the basement, it’s (probably) not a gremlin. If the noises are accompanied by water flooding the room, there’s a good chance you have a sump pump problem. It’s likely that your sump pump is tripping the breaker time and again. But why? Here are five reasons your sump pump is tripping the breaker and what you can look for before calling the pros.
Two of the most common types of sump pumps are submersible and pedestal pumps. Submersible sump pumps can short-circuit if even the smallest thing goes wrong since they’re constantly in contact with water. Most commonly, the sump pump's housing can crack over time from normal wear and tear. This causes water to seep in, tripping the breaker.
Visually inspect your sump pump's housing. If it's letting water in, you might be able to just replace the housing. However, the pump itself may need to be replaced if it's water-damaged beyond repair. Call a pro if you’re having trouble figuring out if the housing is to blame.
A sump pump can trip the circuit breaker if the float switch stops working. The float switch controls the water level, and the switch should rise and fall with each cycle. If the switch stops working properly, it can cause the sump pump to overload or dry-run. This results in the sump pump frequently cycling on and off, which can overload the breaker.
Check the float switch's position and see if it's stuck. Float switches can get stuck or fall apart from age and normal wear and tear.
Sump pumps have mechanical seals that keep the pump windings safe. If these seals break, water can get into the pump windings. Seals often break because a bearing gets worn down over time, allowing water to seep in. This can cause the pump shaft to seize and increase the starting current too much, shorting out the circuit breaker.
Check whether the mechanical seals are broken or loose, and call a pro to replace them if needed.
Impellers rotate inside the pump to create suction. If the impeller is broken or clogged by debris, mud, gravel, or other materials, the pump has to work much harder to move water to the sump pit. This makes the pump overheat and use more power than normal, causing the circuit breaker to trip.
Check the sump pump's impeller to see if anything is causing a blockage. If a natural disaster just occurred in your area or you’ve recently had some kind of property damage, it's common for the sump pump breaker to keep tripping because of a clog.
Check that the impeller is free from clogs. You may need to learn how to unclog a sump pump and what its normal operational state should look like.
Faulty parts, clogs, and leaks are all common signs of overloading. The harder a sump pump has to work, the more likely it is to trip the breaker because the components and wires are overheating. Overheating and overworking cause the motor to draw more current, resulting in a breaker trip. Sump pumps connected to the same circuit as high-power devices will also easily become overloaded.
Wiring issues are also a common electrical culprit of sump pump shorting. If your home is older, the wires can be worn out from age and decades of use. Additionally, sump pumps that were incorrectly hooked up to the wires can cause the breaker to trip.
If you suspect that electrical issues are the cause of the problem, you should contact a local sump pump installer to correctly diagnose it. They may be able to handle the wiring problems. If your sump pump is connected to the same circuit as another high-power device, a local electrician can create a new circuit for you.
Sump pump failures are more likely to be mechanical than electrical. Before looking into electrical reasons, like bad wiring, check that the float switch isn't stuck in the ON or OFF position so that the sump pump cycles correctly. Check for broken parts, housing, seals, and other parts that may have cracked or come apart due to age and normal wear and tear.
Sump pumps last about 10 years. With regular maintenance, you may be able to get 12 to 15 years out of your sump pump with typical usage. Poorer quality sump pumps may only last six to eight years, and higher quality models will last longer. If you forget about routine sump pump maintenance and inspections, the pump will not have a very long life.
If your basement gets flooded because of a malfunctioning sump pump, most insurance policies won’t cover the damage. You would need to add a rider or endorsement to your policy that covers water damage, which may or may not be an option depending on where you live. However, even with a rider or endorsement that promises to fix flooded basements and replace lost possessions, your sump pump needs to be regularly serviced and maintained to qualify for a payout.
