"EXCELLENT! It was a somewhat emergency call because my walls were being damaged by the water, and Matt replied right away to my call trying to fit me in. He text back and said one of his guys, Ryan, was available and on his way! Ryan was great! Courteous, professional, punctual (and bonus - he unclogged the bathtub drain!). Thank you for saving the day!"

"We had a damp crawlspace. John's installed drainage with sump pumps (lead and backup with battery backup power) and encapsulated the dirt with 20 mil plastic. They also installed PU foam around the perimeter foundation walls to complete the insulation envelope of the house and a dehumidifier top keep the crawlspace area dry. In short, this work solved the problem we had and provided the added benefits of a more energy efficient and comfortable house due to the insulation as well as better indoor air quality. The work was done in four days and at considerably less cost than a competing contractor bid to do it. Another person that we had inspecting house later looked at the crawlspace and commented, "Wow! You could do brain surgery down here." We actually wouldn't recommend that though ;)"

Sump Pump Installation FAQs, answered by experts

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.

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.

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.

Every three to four months, you should clean any dirt and debris off of your sump pump. You should also check the inlet screen (at the bottom of the pump) to make sure that it isn’t blocked. On top of that, you should deep clean your sump pump once per year—or hire a sump pump pro to do it for you.

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.
