I thought they did a great job. The person I spoke to at the company was very knowledgeable and helped me figure out what i needed to do right away and what could be delayed a bit. They cleaned my entire system. The tech they sent over was super nice and a hard worker; he didn't stop the entire time he was over and he worked for hours. I was so pleased with their services that I later had them come back and install a reverse osmosis system which works great and came out really nice. The water is delicious. Will definitely use them going forward for all water related needs.

All ended EXTREMELY Well with my broken well thanks to Frank and Andrew from KPS!…read moreI honestly can't write a more effusive review for this outstanding family owned business. Within 2 hours of my code red call to Frank because we had NO Water and no clue as to why - Andrew was here within 2 hours ( shocking because we live in a remote area of CT and rarely do folks show up on time and in some cases they don't show up at all) to quickly assess the problem, propose a resolution and provide transparent AND fair pricing. Frank and Andrew return early the next morning with all the necessary equipment and removed and replaced the broken pump and had water back up and running to our home by 3 PM that afternoon!!! This was no easy task- the well was literally in the forest, far from our home and the area around the well overgrown so access was tricky and difficult- this did not dissuade them in any way, nor did it drive the price up. The entire experience was a 10 out of 10! Thank you both so much for delivering outstanding service in our dire time of need !!!
