"I felt the need to write this review, although technically Greg and I have never done business. In the recent round of rain storms, my sump pump stopped working as it is supposed to, and I ended up with about 5 inches of groundwater in the basement. I was able to get the sump pump working again, but 3 days after it stopped raining, I was still getting a lot of water in the pit. I found a sticker for Contractors Waterfproofing, and figured they might of installed the system for the old owners, so I gave them a call. From the moment he picked up Greg was service oriented and responsive. He asked for my address to look up the job, and when he couldn't find it, he called back within 5 minutes to ask what was going on. I explained the problem, and he immediately told me that was normal for my part of town, and told me I just needed to replace the pump and I would be fine. He offered me a price that was half what his competitors charge, and was willing to explain the whole job in detail."

"I really liked CT Basement systems. The sales rep walked me through the process of the basement SaniDry I had installed. When the installer came it turned out that I didn’t need all of the duct work and I was able to save a few hundred bucks. The installer was very professional, neat and helpful . I definitely will hire this company again. Customer service even followed up with me a few days later and had to remind me to register the system (good thing because I had forgotten)."

Our shower was dripping.  We had called another plumber, who said he couldn't get to us until July.  My husband called Atomic Rooter from work.  They came to our house that evening, and completed the job in less than an hour.  They arrived on time and were courteous and professional.  The plumber had the part with him and was able to install it quickly without having to turn off the water in the house.  They accepted our credit card.  We would definitely use them again.

Sump Pump Installation questions, answered by experts

No. Sump pumps have different capacities, which refers to the volume of water that they can remove. They also come in various horsepower ratings, which measure the size of the pump’s motor. For many homes, 1/3 horsepower is enough. But if you live in an area that floods often, you might need a more powerful model.

Start by calling a plumber if you want to install a sump pump battery backup. Talk to them about your situation and needs. Sometimes, electricians or waterproofing contractors will install a battery backup, and in that case, the plumber you call should be able to point you in the right direction.

Installing a battery backup for your sump pump is recommended, particularly if you live in an area with frequent power outages or severe rainstorms. A sump pump requires electricity to function, and a battery backup ensures it can continue to move water out of your home if the power goes out, providing crucial protection against flooding. Additionally, frequent power outages can create electrical surges that might damage the sump pump's motor. A battery backup system offers an additional layer of protection, ensuring your basement stays dry.

Sump pumps prevent basement flooding, reduce humidity, and protect against water damage.

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.
