Water Softener Services in Londonderry, NH

Hard water shows itself in white scale on faucets, spotted glassware, soap that won’t lather, and skin that feels dry after a shower. Hardness and iron vary from home to home in Southern New Hampshire, and both put extra strain on water heaters, dishwashers, and the rest of your plumbing.
At Mainline Plumbing, we handle water softener installation from the first hardness test through setup, and we repair softeners that have stopped doing their job. We size each unit to your water and your household, so it softens properly without wasting salt or water.
Our Water Softener Services in Southern New Hampshire
Whether you’re adding a softener for the first time or fixing one you already own, we start by finding out what’s in your water.
Whole-House Water Softener Installation
A whole-house water softener treats water where it enters your home, so showers, laundry, and every faucet get the same softened water. We use ion exchange, where the unit swaps hardness minerals for sodium or potassium and flushes them away during regeneration.
Water Softener Repair and Service
A softener that isn’t softening, runs through salt too quickly, or regenerates constantly needs a look. We diagnose the problem and repair what’s worn out, and we’ll tell you honestly when an older unit costs more to fix than to replace.
Iron and Manganese Removal
A softener can handle small amounts of iron, but higher levels need an iron filter in front of it or the unit’s resin will foul. We check for both with well water testing and can pair a softener with our whole-house water filtration systems when your water needs it.
When to Consider a Water Softener
If a few of these sound familiar, hard water is probably the culprit. Here are the signs to watch for.
- White scale on fixtures: Faucets, showerheads, and kettles crust over.
- Spotted dishes and glassware: Even after a full cycle, dishes come out cloudy.
- Dull laundry and dry skin: Soap doesn’t rinse cleanly in hard water and can lead to duller clothes and dry skin.
- Rust-colored stains: Iron may be present along with the hardness, leading to staining.
- A shorter life for appliances: Scale builds up inside water heaters and dishwashers.
A softener can cut down on scale buildup and soap use over time, though a test tells us whether your water actually needs one.
What to Expect During Water Softener Installation
The visit goes in a predictable order, and we explain each part.
- Water testing: We measure hardness and check for iron and manganese.
- Unit sizing: We choose a softener that fits your water and the number of people in your home.
- Installation: We connect the unit to your plumbing, set up the drain line, and add salt.
- Final walkthrough: We show you how to check salt, adjust settings, and spot trouble early.
Softeners need regular salt refills and an occasional check, so we’ll point out what to watch for.

Frequently Asked Questions
Cost depends on the size of the unit, how hard your water is, and how much plumbing and drain work the installation needs. A household with iron or manganese may also need a filter ahead of the softener. We test first and explain your options, and offer financing for larger projects.
The cost depends on what the softener needs, whether that’s a small adjustment, a worn part, or a bigger repair. We diagnose the problem first and explain your options before any work begins, and financing and specials are available for larger repairs. If an older unit costs more to fix than to replace, we’ll tell you so.
It’s strongly recommended. The unit has to be tied into your main water line, a drain, and often your electrical supply, and a plumber makes sure the connections meet code and won’t leak. A bypass valve and proper sizing matter as well.
