"Inspection of a previously installed sump pump system (primarily the sump pump). Inspection found that it seized up and wouldn't have functioned. Replacement made - and very fortunately - since when the pump is needed, it IS needed. It wouldn't have been good to have a flooded basement or have an upcoming flooded basement."

"1) My kitchen faucet & sink food disposal needed replacing. I purchased both from Home Depot & phoned Home Advisory for plumbing service to install. Home Advisory gave me Brian's phone. I called and left a message. 2) Brian Nisbet responded to my voicemail within minutes saying he was on a job in my city of Stamford CT & would call me as soon as he finished to look at my job. As soon as he called we removed all the bottles & clutter in the cabinet beneath the sink. 3) When Brian arrived the new faucet & food disposal still in the sealed boxes were sitting there in front of the vacant cabinet. 4) He quoted a very reasonable fee, we agreed, and immediately crawled partially under the sink and began the installations, and carefully tested for leaks of which there were none. 5) Amazingly we had both installations completed within hours from the beginning of purchasing the product & completion. 6) CAUTION: If you're purchasing the popular Badger disposal make sure that you copy the s/n number BEFORE the installation because it's located in the back of the disposal, and you'll need the s/n number for the warranty. I had to empty the cabinet all over again & crawl under there with a flashlight just to copy the s/n (serial number. The manufacturer should place it in the front."

"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)."

"Mike was great. He gave a very competitive qoute and took the time to explain the work that he would be doing. He was very professional and helpful from beginning to end. He installed a new Combi Boiler for us in 2 days now we have hot water and heat working perfectly once again. I would recommend Mike for any job."

Sump Pump Installation questions, answered by experts

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.

If your sump pump isn’t engaging, it might be clogged with dirt and debris. Check to see if the fitting lid is loose and has been letting debris in. Next, check the float and make sure it’s not obstructed by rust or gunk, which results from insufficient maintenance. Tangled wires or damaged switching systems can also stop your sump pump from engaging.

If you notice any new sump pump noises, such as persistent clanging or gurgling, then you likely have a sump pump problem on your hands. Foul odors coming from the pump can also indicate problems. Additionally, if your unit turns on but doesn't pump water, you might have to address electrical problems. In any of these cases, it's a good idea to hire a professional to address the issue.

The life span of a water pump ranges from five to 15 years on average. Regular maintenance can extend its life. If you notice significant drops in performance, strange noises, or frequent malfunctions, consider a water pump or well pump replacement. Always get in touch with a professional if you're concerned about yCan I install a water pump myself?our pump's condition.

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.
