"Harts corrected the location of the crawlspace sump pump discharge line to the location in the foundation which I originally wanted it to be located. However, we did not hear the sump pump operate under the floor when first installed. When the Harts crew changed the location of the pump discharge line, we can now hear the pump very distinctly when it operates, under the floor. I am requesting that Harts come back and listen to see if it is normal for the sump pump to make this much noise."

"G&S did an excellent job installing our new furnace and AC unit. The best thing about G&S is that they warranty for 1 year. The circuit board in our furnace failed within a couple of months (no fault of G&S). Manufacturers warranty would cover the parts cost but G&S repaired and covered labor cost under their warranty. Also they diagnosed the issue and repaired very quickly. Definitely A++ installation and service."

"Determined sump pump failure was not due to electrical issues. They kept me posted by text prior to arrival. Showed up on time. And even made phone calls to a plumbing group to get them out as soon as possible. The tech went out of his way to get us the help we needed."

"Don't hire anyone else. If you're looking for a company run by someone who understands what customer service looks like, call Perma-Dry. 4 years ago we worked with Perma-Dry to install an internal basement footing drain system - they were prompt, responsive, and did a great job. We've had zero issues. We recently discovered an issue with an old external drainage system (not installed by Perma-Dry) which backed up during a thunderstorm. When I discovered the issue, I called Ryan (owner) to get some help; he showed up at 9am on a Saturday (his day off) and spent 5 hours with me troubleshooting the issue and coming up with a temporary fix until he could get a crew out to install a permanent fix. He not only was a huge help, but his attitude was incredible - he was actually having fun working on his day off. In the 12 years I've owned my house, I've worked with dozens of contractors and never had an experience like that. True customer service is a lost art, Ryan and his team have shown us twice that they understand how to take care of customers and care enough to do the right thing."

Sump Pump Installation FAQs, answered by experts

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.

Submersible and pedestal sump pumps are two popular types of sump pumps. Submersible models are covered by water in a sump pit, which helps keep the motor cooler and quieter. Pedestal sump pumps stick out of the sump pit, so the motor stays dry and is easier to access. Submersible sump pumps are the pricier option, but they also have longer life spans.

Yes, many modern water pumps are designed with energy efficiency in mind. Look for pumps with high efficiency ratings or those with an Energy Star certification. These pumps consume less power and can reduce your utility bills. Additionally, variable-speed pumps are more efficient since they can adjust the flow based on demand, providing significant savings over time.

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.
