Water filtration & softening

Most of the Monadnock Region is on a well. Hardness, iron, manganese, sulfur smell, low pH eating your copper, every one has a different fix. We start with a water test, not a catalog.

What we carry

Water filtration & softening, specified with the room

Test

Start with a test

A lab water test tells us hardness, iron, manganese, pH, arsenic and bacteria, the treatment is designed to those numbers.

Soft

Softeners & conditioners

Ion-exchange softeners for hard water, and salt-free conditioners where scale, not sodium, is the concern.

Filter

Whole-home filtration

Environmental Water Systems multi-stage filtration for taste, odour, sediment and chlorine, at the point of entry, so every tap benefits.

Problem

Iron, sulfur & pH

Air-injection iron filters, catalytic media for the rotten-egg smell, and acid neutralisers to stop low-pH water corroding your pipes and fixtures.

Drink

Drinking water

Under-sink reverse osmosis at the kitchen and the bar for drinking and ice, with a line to the fridge.

Protect

Protect the fixtures

Untreated hard or acidic water shortens the life of every faucet, valve and water heater in the house, the filtration pays for itself downstream.

Do I need a water test first?

Yes, always. Well water in the Monadnock region varies house to house: hardness, iron, manganese, sulfur smell, low pH, arsenic. The lab numbers determine the treatment; buying a softener off a shelf without a test often fixes the wrong thing.

Softener vs. filter, what is the difference?

A softener removes hardness (calcium and magnesium) so you stop getting scale and can actually rinse soap off. A whole-home filter handles taste, odour, sediment, chlorine and specific contaminants like iron or the rotten-egg sulfur smell. Many wells need both.

Will it fix water that eats my copper pipes?

Low-pH (acidic) water corrodes copper and leaves blue-green stains. An acid neutraliser raises the pH before the water reaches your plumbing, one of the highest-value fixes on an older NH well.
