"Amazing. YES - you pay a lot - but they rocked, their solution rocked, and the installation was flawless. We just built a brand new home and the builder put in the cheapest 24" deep sump pump possible. We live in an area known for basement flooding so I did my research - had several companies come in - and settled on Connecticut Basement Systems. But my LORD - expensive. But now I know why. Their crew of 3 showed up and laid down plastic mat from our front door all the way down to the basement (at least 200'). It was over kill - but then I saw why. They had to dig a 36" deep pit and a wider hole - and brought up all the mess in buckets. NOT A SINGLE DROP ON THE BASEMENT FLOOR OR ONE THE WAY UP THE STAIRS. In fact - if you didn't see the high tech 3 pump sump pump they installed - you would have never known they were there. EVERYONE was super nice and answered all my many questions. I just spent a year in **** building a new home - and this was the best experience I've had with a contractor in 10 years. Pay the bucks - great product - great installation - great service."

"I had their technician (Julian) hook up & tested my pool pump, also fix a clogged toilet. Julian was very thorough and explained everything that needed to be done through the entire job. Couldn’t be more happier with their service, I do find their price is on the high side, however I would definitely recommend & hire them again as not all plumbers or even pool company would come & hook up existing pump"

"Extremely satisfied.  Company was responsive (My initial call to them was on Xmas Day when I noticed the sewer backed up in my back yard).  They called me back immediately and  agreed to send someone to look at it the next day (after ansering some questions, we agreed it was not an emergency) - they came the next day as promised and even called prior to their arrival.  The plumber assessed the situation and took pictures to send back to Larry.  I spoke with him and agreed to have them come back on Monday when the equipment  needed to address would be available (needed an extra long hose and camera set up given the location of the cleanout cup).  Each time dealt with the company (Larry) he would call to let me know status and options.  On the day they came, Larry and his associate were at my home at the time promised.  Spent nearly 3 hours and all is well.  So although a bit pricey, well worth it given the responsiveness and professionalism of the company.  Would highly recommend them for any of your plumbing needs.

Sump Pump Installation questions, answered by experts

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.

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.

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.

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.

If you’re wondering if your home even needs a sump pump, consider whether you’ve struggled with flooding issues in the past. If your house is in a flood-prone area, your yard has poor drainage, or you’ve dealt with any other water problems, then it’s likely well worth it to replace your old sump pump with a new one.
