Specifically designed for your water

Specifically designed for your water.

By testing water samples and analyzing data from numerous 3rd-party sources, the NH Tap Mainframe Whole House Water Filtration System is able to create up-to-date water quality profiles for individual New Hampshire towns and cities. This ensures our systems are tailored to your home’s specific water needs.

Let’s find out what’s in your water.

Superior Water Filtration

Superior filtration technology.

As the impurities in tap water meet the filtration materials, an elemental reaction occurs, giving you clean water. Our system’s technology causes impurities to bond with the filtration media, trapping and destroying them before they can be circulated into the home.

Purified water does not harm your health with toxic chemicals like PFOA, chlorine, or heavy-metal lead. This is the safest, most cost-efficient, and effective way to purify water on the market.

Longer lifespan, simple service.

Longer lifespan, simple service.

We have complete oversight of our production process, giving you a superior product that outperforms and outlasts the generic filters commonly installed by most plumbing contractors and well service companies. Installing a NH Tap Mainframe Whole House Water Filtration System allows you and your family to enjoy healthy drinking water and hot showers with absolute peace-of-mind for years to come.

We offer a 5-year warranty to back our incredible whole house water filtration systems and can provide regular maintenance service to help your unit last a lifetime!

Each NH Tap Mainframe is tailored to treat common contaminants found in New Hampshire public water.

The question is not whether your municipal water is contaminated. But rather just how bad is it, and what will you do about it?

In the past, homeowners assumed that because they were on municipal water, their water was clean—or at least clean enough. However, new research continues to find that treated water traveling through antiquated public infrastructure is often teeming with heavy metals, industrial chemicals, and natural contaminants. The only immediate solution is to remove contaminants at the individual home level.

“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!”

“NH Tap was extremely knowledgeable about the water issues in our town. They were focused on giving us the best solution to give us the cleanest water. The whole process from initial consultation to installation was very easy and the process was well explained. The end results were exactly what we were looking for, clean water with no chemicals. I highly recommend NH Tap.”

All your questions answered.

Because municipalities are required to publish regular water quality reports, NH Tap is able to gain a lot of information about any contaminants that may be in your water—before we step foot in your home. We may be able to provide you with ballpark pricing over the phone. However, because the plumbing and floorplan of every home is different we do need to inspect the home to provide an accurate quote. An in-home visit will only take a half-hour and we can work around your schedule. We’ll have a no-obligation quote to you within 24-hours.

Our turnaround time is 1 - 3 weeks from consultation to installation.

Your system should last a lifetime. But your filtration media will last up to 5 years and then will need to be replaced. We provide a scheduled service that lets you put your water on auto-pilot!

Yes. We offer easy-term financing with zero down & low monthly payments. Contact us today for a quote!
