Each system unit, specifically designed for your water.

A preliminary lab analysis identifies the well’s chemical makeup. The NH Tap Absolute Well Water Filtration System uses a combination of the filtration units to eliminate any detected water contaminants.

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.

Clean Filtered Water

Long lifespan, easy 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 Absolute Well 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 product and can provide regular maintenance service to help your unit last a lifetime!

“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 They replaced our well tank and replaced our old, outdated water filtration system with a new, state -of-the-art tank & system that we love!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.

For private wells, NH Tap will need to test your water to determine its chemical makeup. Many contaminants can be tested on-site, but certain contaminants such as arsenic will be sent to an independent lab for testing. Once the lab results come in (usually within 1 week), we will share them with you and provide a quote for any necessary remediation.

You should have a fully functioning system in 1 - 3 weeks — from initial consultation to installation.

Your system should last a lifetime. But your filtration media will last up to 1-10 years, depending on your water’s chemical makeup. We can get you on a service schedule that puts all your water needs on autopilot! Contact us today for more information on water testing and a system quote.

A well water filtration system takes the water coming in from a private well and removes all impurities before allowing water to flow through your home. Unlike Reverse Osmosis Systems that remove contaminants at a dedicated drinking water faucet, a whole house well water filtration system covers every faucet in your home for drinking, cleaning, or bathing.

Common contaminants we find in New Hampshire well water include Aresenic, PFAs, Hard Water, Iron, Acidic Water, sediment in water, and hydrogen sulfide (rotten egg smell), and Radon. Our Absolute™ Well Water System has been specifically designed to remove all of these issues and cover all your well water filtration system needs.

Well water filtration units often cost more than municipal water filtration systems as they may need to consider additional contaminants that city water filters out at the municipal level. Costs typically run about $2,000—$7,000 installed. Make sure your well water filtration system is installed by a professional plumber and comes with a multi-year guarantee on the product and the installation as problems that arise can be costly if not handled professionally. While purified water can be a significant investment, the long-term benefits to your health and the reduced wear-and-tear on your homes plumbing and appliances greatly offsets the initial expenses.

The best well water filtration system is the one that provides the most specific water filtration media to address your home water needs. We test each customer's well water to customize a system unique to the chemical makeup of your well water and your water usage. Our Absolute Well Water Filtration System takes water through a series of specialized filtration units chosen to remove the contaminants found in your well. Each Absolute™ unit in your system targets a single contaminant — ensuring clean water for a longer service life.

There are typically two filters to consider when maintaining your NH Tap well water filtration system: the sediment filter and the filtration media tank.

The sediment filter is the first inline from your home water line and has a blue canister with a cartridge inside. These cartridges should be replaced every 1 to 6 months. Replacing this cartridge is a simple task, but it is important to keep up with these as a clogged sediment filter can reduce or completely stop water flow.

Maintaining your filtration media tank is even simpler. Your NH Tap whole house water filtration system has automatic regeneration cycles that can be scheduled specifically to coordinate your water usage and lifestyle. These ""re-gen"" cycles greatly extend the lifecycle of the filtration media versus older or lower quality systems. Eventually, your filtration media will need to be replaced (usually within 2–5 years depending on your water use). This is a simple process of exchanging the old media tank for disposal and replacing it with a new media tank.

We recommend setting up scheduled maintenance visits so that your unit can continue working well for years to come. Once you sign up, we send out trained technicians regularly to inspect and maintain your unit, so your fresh water is always on autopilot! Enjoy peace of mind and one less thing to think about!

All NH Tap well water filtration systems include professional installation in the quoted price. While a handy homeowner can install a big box store unit themselves, NH Tap whole house water filtrations are always installed by a licensed plumber to ensure quality workmanship and a long lifestyle for your system.

To install, our plumbers typically will:

  1. Choose the filtration unit's location.
  2. Turn off the building's water supply.
  3. Remove a part of the pipe near the water main shutoff valve, where you can mount the unit on the wall or floor, and remove burrs.
  4. Install the copper tees and connect them with a pipe and ball valve.
  5. Depending on the unit and whether you have a pre-filter or not, add a ball-valve on either side, dry fitting it all. Mount the units, continue the piping, hooking it up with a dry fit.
  6. Clean your copper lines with an emery cloth. Use the deburring tool to finish it. Apply flux and solder the connections.
  7. Add a grounding jumper cable if you have copper or galvanized pipes.
  8. Carefully route drain lines to avoid spilling or freezing and causing damage to the home.
  9. Remove and dispose of any old equipment.

As always when dealing with water in the home, we feel strongly that an ambitious homeowner can save money in other places, but handling the installation and maintenance of a whole-home water filtration system is best left to the pros.
