"Gavin Gordon was the inspector. He identified the problem areas and spent time explaining all the details of the job. Dylan and the rest of the crew did a great install and the Miami office was a great experience. Very professional all around. Would definitely recommend this company."

We offer an overheat protection switch to keep your pumps protected. Our price point is far better than what would cost you to replace your well and centrifugal pumps. Preventive care is always better than reactive care. Aside from distributors and pump manufacturers, we don't have return clientele because our switch works perfectly. 5 minute installation and a product made in USA that is less than $200. Patented product.

Sump Pump Installation FAQs, answered by experts

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

There are several indicators that your washing machine’s drain pump is bad, including incomplete cycles, water not draining, lack of spinning, a foul odor when the machine is running, and a loud grinding or buzzing noise when the pump is trying to move water down the drain.

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.

Most sump pumps come with power cords that can be plugged into an outlet, but there are options that can be hardwired into a home’s electrical system. Either way, it’s smart to have a backup power supply in case the electricity goes out during a storm. That way, the sump pump can keep running and removing water from the sump pit.
