The NH Tap story.

A Journey from Granite State Roots to Clear Water Solutions

At NH Tap, our story is rooted in the Granite State’s natural beauty — and one New Hampshire native’s commitment to tackle our state’s biggest water challenges head-on.

Keith McDonald grew up in the small town of Jaffrey, surrounded by clean air, forests, and fresh streams. But as he got older and learned more about what’s really in our water — from aging pipes to chemical runoff and natural heavy metals — he knew New Hampshire families deserved better.

Keith dove deep into researching local water systems, old infrastructure, and the hidden contaminants that too often slip through. He spent years studying water chemistry and filtration design, determined to build a solution that could handle New Hampshire’s unique mix of minerals, metals, and emerging chemicals like PFAS.

With his years of research and field experience, Keith put his knowledge to work right here in New Hampshire. He engineered comprehensive whole-home purification systems designed specifically for the state’s unique water challenges — removing what generic filters can’t.

That’s how NH Tap was born: not just a business, but a local company built to help Granite Staters protect what matters most. Today, we’re proud to be part of the community — testing, educating, and installing solutions that make New Hampshire’s water as clean and healthy as our beautiful landscape.
