Of NH municipal water contains PFAS, that are linked to cancer as well as hormone, immune system, and fertility issues.



New Hampshire home wells contain unsafe levels of arsenic, a known carcinogen.



Higher bladder cancer rates are due in part to high arsenic levels in local NH wells

“I had NH Tap install an entire home water purification system 2 months ago, and it was one of the best investments I ever made. I continue to smile whenever I get a glass of drinking water directly from my home tap, and it is delicious. NH Tap provided excellent service, explained all my options in detail, showed me the factual information about my town's water system, and professionally installed the system with the highest of quality. I highly recommend NH Tap without reservation, and I look forward to calling them in 5 years to replace the carbon filter system.”

“Keith, Nate and the team at NH Tap did an incredible job on our system! They replaced our well tank and replaced our old, outdated water filtration system with a new, state -of-the-art tank & system that we love! We are already seeing and tasting better water from our well thanks to NH Tap. Their installation was flawless and well-organized. Nate and his team were very professional and were a pleasure to have working in our 1779 farmhouse. They left everything spotless! We would highly recommend NH Tap based on service, price and over-all professionalism. My wife and I are very satisfied with the whole experience!”
