Job Stories From Plainville, CT
TripleSafe Sump Pump Installation in Plainville, CT

This Plainville, CT family was tired of their old sump pump failing time and time again. Where it sat was covered in dirt and debris, and it was beginning to clog. They gave us a call at Connecticut Basement Systems, and we knew our TripleSafe Sump Pump was just the solution that they needed. High-volume, reliable, and attractive, this system includes two sump pumps and a battery back up that can pump over 11,000 gallons of water when the battery is fully backed up. It also offers an air tight lid, that keeps pest and debris from flying inside, which keeps the sump pump from clogging. Now, this family can live comfortably, and know that their new sump pump won't give them the same problems their last one did.
