Water Quality used to be a nonissue. But with pharmaceuticals in water supplies, the effects of chlorine, industrial and biological contamination, an aging water distribution infrastructure and naturally occurring substances that degrade the taste and feel of water...we're all thinking about the quality of our water more than ever.

Water Quality varies from home to home. Water treatment for one family may not be right for another. Depending on the water issue, the solution may address all the water in your home, (point-of-entry) or only water that is dispensed from a specific tap (point-of-use). The method of treatment and the type of water desired will also determine what’s right for you.

  • Water Softening
  • Water Purification
  • Water Filtration
  • Saltless Water Conditioning Systems
  • Whole House Water Treatment Systems
Types of Filters:
  • Mangenese Greensand Plus Filters – Iron, manganese and sulfur are oxidized into solids and trapped in the filter bed where they get flushed to the drain.
  • Birm Filters - Remove soluble or precipitated iron without the use of expensive or messy chemicals.

  • Taste & Odor Filters – Remove bad tastes and odors caused by chlorine & organics.
  • Neutralizing Filters – Raise the pH of acidic water to neutralize corrosiveness and protect fixtures, pipes and appliances.
  • Multi-Media Filters – Eliminate suspended sand and silt that makes water cloudy.
  • Nexsand Turbidity Filters – Remove suspended solids, Ferric Hydroxide (Red Water Iron) or Sediment from your well or water system down to 5 Microns. Nexsand has proven extremely effective and will provide double the service flow of Multi Media or Sand Filters.
  • Chloramines Removal Filters – This system uses special catalytically enhanced carbon and provides improved bed depth and contact time for more effective reduction of chloramines.

The Trouble With Hard Water (calcium & magnesium) is a common problem for many homeowners and businesses. When hardness minerals are combined with heat it forms troublesome scale. Scale causes costly build-up in your plumbing, water heater and other water using appliances. When combined with soap, the minerals form soap curd or scum that makes skin dry and itchy, hair lifeless, laundry dull and builds up on fixtures.

    Benefit From Softer Water:
  • Silky shiny hair, Soft supple skin
  • Use up to 75% less soap
  • Lower water heating cost by 29%
  • Save as much as $479 annually* (*Potentialy)
Radon Air & Water Mitigation (Radon Mitigation NEHA # 105931RT)

It is during the course of water usage that radon escapes from water and will accumulate and raise the radon level in your home. It can pose an increased health risk, primarily lung cancer. An additional health risk is associated with the ingestion of the radon that remains dissolved in the water and is consumed. On average, this latter risk is substantially lower than that associated with inhalation. The risk from radon in water is relatively high when compared to other drinking water contaminants.

  • Radon is a tasteless, odorless gas created by the decay of the element radium which is in New Hampshire’s soil and granite.
  • No Level of Radon is Safe – even trace amounts in your home can be dangerous to you and your family…
  • Radon is the second leading cause of lung cancer and is the leading cause of lung cancer for non-smokers. A combination of smoking and radon exposure vastly multiplies the risk. New Hampshire radon mitigation is of the utmost importance to avoid this.
  • Radon in water comes into our home during normal household activities such as showering, dishwashing and doing laundry. It is immediately released into the air where it is typically held captive causing us to breathe it in. Radon is reported as pico Curies per liter.
  • If you haven’t tested your home for radon since you moved in, it is important to take the initiative to find out what level of radon is currently present.

What is Arsenic?
Arsenic (As) is a naturally-occurring element in the earth’s crust and traces of arsenic can be found throughout the environment. Arsenic in soil may originate naturally, and past human activities may have added to these levels in some areas. Historically, the heaviest use of arsenic in this country has been as a pesticide. The current predominant use of arsenic is as a wood preservative. In ground water, arsenic occurs primarily in two forms, As+3 (arsenite) and As+5 (arsenate). Organic arsenicals are not known to occur at significant levels in ground water. Arsenic may change chemical form in the environment, but it does not degrade.

How can I reduce arsenic levels in my water?
There are two methods of treatment that our commonly implemented for arsenic removal:
1) point-of-entry treatment (POE) systems treat the water for the entire household.
2) point-of-use (POU) systems treat the water at the kitchen.

Only you can make the decision on what method of treatment works best for your lifestyle and budget. Feel free to contact us at your convenience and we would be more than happy to help in any manner we can.

Well Pumps (New Hampshire Well Pump Installer License # 1354)
There are many types and sizes of pumps for water systems. Some are only designed to remove water from a source. Others not only remove the water, but also force it through the rest of the water system. Some pumps are for special jobs such as boosting pressure or supplying a special outlet. Booster pumps are to be installed after a storage tank, if your pumping installation is not properly planned, you will not receive satisfactory water service.

Pressure Tanks
Pressure tanks provide storage for your water system. There are three general types of water storage tanks:

  • Diaphragm bladder tanks with permanent separation between the air and water;
  • Tanks with a float or water separating the air from the water (not used in recent years)
  • Plain steel tanks – each kind of tank serves a specific purpose.

Constant Pressure Pump System
SQE Pump and Motor
The SQE is the only constant pressure pump on the market fully equipped with built-in electronic controls which allow for advanced computer controlled performance and state of the art protection features including sophisticated diagnostics. The motor design is a Variable Speed Drive which electronically changes the pump speed to match demand providing you with the incredible comfort of constant pressure.

Each unit is equipped with:
Soft start – prevents water hammer and motor overheating
Dry run protection – pumps are water lubricated and if your well runs low, an unprotected pump will die
Overload protection – if a pump becomes clogged with debris like sand or grass, it can destroy an unprotected motor
Over and under voltage protection – the lifetimes of unprotected motors can be greatly reduced by improper voltages. Rural parts of the country are notorious for wide variations in voltage supply

CU301 User Interface
The CU301 User Interface is the easy to use command and control computer for operating the pump in constant pressure mode. The user simply chooses the desired water pressure by pressing the UP or DOWN arrows, and the CU301 does the rest.

In order to control pressure, it must be measured. The included pressure sensor precisely measures water pressure sending its signal to the CU301. The CU301 reads this pressure signal and then electronically commands the pump to start, stop, speed up, or slow down in order to maintain constant pressure regardless of water demand. It controls the pump via power line communications by impressing high speed data messages on the pumps power supply cable. This technology is similar to that used in a home intercom or a baby monitor.
