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.
