"I’ve used Mike twice now, last time for a sump pump replacement and water heater flush. Did great work and takes the time to explain what is going on. I don’t feel like he’s trying to upsell services to me like some other plumbers. Highly recommend."

Sump Pump Installation FAQs, answered by experts

In most cases, standard homeowners insurance policies do not cover damage from a sump pump failure or overflow. Coverage for water damage is often limited to sudden, unexpected events like a burst pipe that was not caused by negligence. To be covered for sump pump issues, you will likely need to purchase a specific rider, endorsement, or additional water backup insurance. If your insurer offers this type of coverage, they may require proof that your sump pump is regularly maintained.

A sump pump can be plugged into a regular, 110-volt outlet with three-prong openings, but it must have GFCI protections per the NEC, meaning you’ll need a GFCI outlet and circuit. Sump pumps require two outlet openings, one for the plug to the motor and one for the float switch.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

To maintain your sump pump, start by checking it every three to four months to ensure it’s in working order. Clear any debris from the pit because blockages can prevent the pump from operating efficiently. You should also test the pump by pouring a bucket of water into the pit. If it turns on automatically and drains the water, it’s functioning correctly. Inspect the discharge line for clogs, and ensure it directs water away from your home. Once a year, clean the pump itself, and consider having it professionally serviced for optimal performance.

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.
