Better water starts with better knowledge.

At NH Tap, we believe every New Hampshire family deserves clean, healthy water — and the confidence of knowing what’s really coming out of the tap.

We’re a local New Hampshire water treatment company helping homeowners test, understand, and improve their water with honest guidance and whole-home filtration solutions designed for the Granite State’s unique water challenges. From PFAS and arsenic to lead, iron, manganese, uranium, hard water, chlorine, and other hidden contaminants, our work starts with education and ends with water you can feel good about using every day.

Whether you rely on a private well or town water, NH Tap makes it simple to identify what’s in your water, understand your options, and choose the right filtration system for your home, family, and budget.

The NH Tap story.

A journey from Granite State roots to clear water solutions.

At NH Tap, our story is rooted in New Hampshire’s natural beauty — and one New Hampshire native’s commitment to tackling 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 learned more about what can affect local water quality — from aging infrastructure and chemical runoff to naturally occurring metals and emerging contaminants like PFAS — he saw a clear need for better education, better testing, and better filtration options for New Hampshire homeowners.

Keith began studying local water systems, private well concerns, municipal water issues, water chemistry, and filtration design. He focused on the contaminants that matter most in New Hampshire, including PFAS, arsenic, lead, uranium, iron, manganese, chlorine, and other water quality concerns that can affect health, taste, odor, plumbing, and appliances.

With years of research and field experience, Keith put that knowledge to work right here in New Hampshire. He developed a practical, education-first approach to water treatment: test the water, explain the results clearly, and recommend a system designed around the home’s actual water quality — not a one-size-fits-all filter.

That’s how NH Tap was born: not just as a water filtration company, but as a local resource for families who want to make informed decisions about their water. Today, we’re proud to help Granite Staters test, treat, and maintain cleaner, healthier water throughout the home.

Being part of your story.

We love getting to know our neighbors — and nothing makes us prouder than helping families enjoy safe, great-tasting water.

Our approach is educational, collaborative, and transparent. We test your water, walk you through the results, explain what each contaminant or water quality issue means, and help you compare the options available for your home. Whether you need PFAS filtration, arsenic treatment, a whole-home water filtration system, drinking water filtration, or help improving taste, odor, hardness, or staining, we’ll help you choose a solution that makes sense.

No scare tactics. No confusing jargon. No one-size-fits-all recommendations. Just clear answers, practical options, and support from a local team that understands New Hampshire water.

Our mission. Improving by removing.

We’re on a mission to provide healthier water for homes across New Hampshire.

Every family deserves clean, safe water that tastes great, protects their health, and supports the long-term performance of their plumbing and appliances. Our job is to make that simple. We test, treat, and maintain custom water filtration systems designed to address the biggest water concerns in New Hampshire, including PFAS, arsenic, lead, uranium, iron, manganese, chlorine, hard water, unpleasant taste, odors, and other hidden contaminants.

From point-of-entry whole-home filtration to drinking water solutions, we help homeowners understand what their water needs — and how to fix it properly.

Our commitment.

At NH Tap, your trust means everything to us.

We spend thousands of hours studying New Hampshire’s water challenges so we can recommend solutions based on testing, science, and real local experience. Our recommendations are designed around your water source, your test results, your home, and your goals — whether that means improving drinking water quality, protecting your family from PFAS or arsenic, reducing staining and buildup, or making every shower, wash, and glass of water feel better.

NH Tap is listed by the New Hampshire Department of Environmental Services as a New Hampshire Small Water Systems Service Provider, and we help homeowners understand available state resources, including the NHDES PFAS Removal Rebate Program for eligible private wells.

We’re also committed to long-term support. A filtration system should not be treated as a one-time transaction. It should be installed correctly, maintained properly, and supported by a team that is available when you have questions.

When you choose NH Tap, you’re backed by a local New Hampshire team committed to doing the right thing — before, during, and after installation.
