Protect Your Home from Hard Water

Hard water is extremely common in Southern NH. The calcium and magnesium minerals that cause it leave scale deposits in water heaters, on fixtures, in dishwashers, and throughout your plumbing, shortening appliance life and increasing energy costs. A properly sized water softener removes these minerals before they cause damage.

Common Questions

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 usage depends on your water hardness and household water consumption. Most households use one to two 40-pound bags of salt per month. A properly sized softener uses salt efficiently.

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 design complete water treatment systems that address hardness, taste, odor, and any other water quality issues together.
