Water Softener Installation
and Service in Southern NH
A.J. LeBlanc Heating installs and services water softeners for Southern NH homes. Our licensed New Hampshire plumbers test the hardness and size the equipment to reduce scale, improve water feel, and match the home's demand.
Protect Your Home from Hard Water
Hardness comes from dissolved calcium and magnesium. When an independent laboratory confirms elevated hardness, those minerals can leave scale on fixtures and inside water-using equipment. We size and program the softener from the test result and the household's water use.

Properly Sized for Your Home
Correct sizing balances consistent soft water with efficient salt and water use. We use the tested hardness, household demand, plumbing flow, and regeneration settings to choose the equipment.
Licensed NH Plumbers
Our licensed New Hampshire plumbers install the softener, bypass valve, drain connection, required piping, and controls. We program the system, test the regeneration cycle, and show you how to add salt and adjust the settings.

Frequently Asked Questions
How do I know if I have hard water?
Common signs include white scale buildup on faucets and showerheads, spots on dishes and glassware after washing, flat-feeling hair after showering, and soap that does not lather well. A water hardness test gives you an exact measurement.
How does a water softener work?
A salt-based softener uses ion exchange resin to replace calcium and magnesium ions with sodium ions. When the resin is exhausted, the softener automatically regenerates by flushing it with a salt brine solution.
How much salt does a water softener use?
Salt use depends on the measured hardness, household water use, softener capacity, and regeneration settings. We program the system for the home and explain what to expect at startup rather than giving every household the same estimate.
Can a water softener be combined with a filtration system?
Yes. Many homes benefit from a softener combined with a carbon filter or iron filter. We can combine treatment for hardness with equipment selected for other concerns confirmed by the independent laboratory result.
