"Brian responded promptly, was professional and courteous. He came right away to do an assessment and returned within a few days to install a new water softener system. He presented me with a lower cost option that could have been done same day but I chose to replace a 17 year old system with a new system that is more accurate (better monitors water use) and less costly to operate because it uses less salt. He performed several preventative maintenance updates: re-piped and plumbed in a new particulate cartridge, cleaned the screen on the radon system and replaced the solenoids, all within the cost of what other companies quoted for only the water softener replacement. The last technician that serviced our water systems (Radon & RO) rushed through the job and left them in worse shape than they were before he "serviced" them. Brian recognized the issues and fixed them. I will now be using H20inthe603 for all of my water treatment service. Thank you Brian for a job well done!"

"I had my full home repiped as I switched from electric to forced hot water heating. Fred was courteous, communicative, and timely in making the repairs. We ran into quite a few snafus and he took them in stride. His quote was MUCH lower (about half the price) of the original quote we got. Definitely recommend."

"They did a great job. Outstanding customer service. Communicated very well keeping me updated with all details and explained everything I needed to know about the system. The install went smoothly and the workmanship was very neat. When they completed the job, they cleaned up very well. I would definitely recommend them and actually have already to a friend."

"I can't say enough good things about Stan and Yankee Pump. Not only are they super knowledgeable, but they genuinely enjoy and are experts at their craft. The service is tops, weather you have feet of snow in the way, or its a global pandemic, they are there for you when you need them the most. I appreciate the work and the service beyond words."
