Water Softener Installation for New Hampshire Homes
Hard water doesn’t just leave residue—it quietly wears down your plumbing system over time. From scale-covered fixtures and spotted shower glass to appliances that fail early, hard water is one of the most common issues for New Hampshire homeowners.
At GSMS, we install whole-home WaterSoft® water softeners that treat your water at the source. These systems remove minerals before they reach your faucets, ensuring clean, soft water throughout your home.
Start with a free, state-certified water test, and we’ll help you choose the perfect WaterSoft® system for your family. Call 603-424-8258 to schedule today.

How a Water Softener Works
Zak from our GSMS team explains it best:
“A water softener basically has a tank filled with tiny beads—what we call resin. Those beads collect all the hard scales in your water and absorb it, so what comes through to your home is clean, soft water. Every so often, the system goes through a backwash where saltwater rinses over those beads to clean them off, and then the cycle starts fresh.”
That’s the process at the heart of every WaterSoft® system. Using ion exchange, these resin beads trap hard minerals like calcium and magnesium. When the beads reach capacity, the system regenerates automatically, flushing out the minerals and preparing for another cycle of softening.
The WaterSoft systems we install utilize the advanced ISOBAR 4 control valve with Legacy View Bluetooth technology, enabling on-demand metering, fine-tuned programming, and efficient salt and water use—all without requiring an internet connection.
Water Softener FAQs
No. The salt is only used to clean the resin beads—it doesn’t affect your drinking water.
Yes. WaterSoft® systems use a low-water backwash that’s safe for septic fields and conserves water.
Yes. We recommend pairing one with every whole-home softener to protect valves and resin media.
Typically once every few weeks, depending on water usage. GSMS can manage refills for you.
Yes. The City Water Softener reduces chlorine and chloramine taste and odor along with hardness.
Yes. The Legacy View™ Bluetooth app allows our team to monitor and fine-tune your system securely.
We size each system based on household water use, fixture count, and hardness levels so it regenerates only as needed—maximizing performance and efficiency.
Common Signs of Hard Water
Are you unsure if you have hard water? These are the telltale signs New Hampshire homeowners often notice:
- Spots and film on shower doors and dishes – White or cloudy buildup that doesn’t wipe away easily.
- Dull, chalky fixture finishes – Hard minerals cause faucets and sinks to lose their shine and develop patina.
- Soap that won’t lather – Hard water prevents soap and shampoo from getting sudsy, leaving skin and hair feeling dry.
- Clogged aerators or showerheads – Mineral deposits restrict water flow over time.
- Frequent appliance repairs – Dishwashers, coffee makers, and water heaters accumulate scale that shortens their lifespan.
- Dry skin and stiff laundry – Residue left by hard water irritates skin and dulls fabrics.
If you’re noticing these issues, your home will benefit from a whole-home water softener installation to protect plumbing fixtures and improve water quality everywhere you use it.
Water Softeners We Install in New Hampshire
GSMS installs the most efficient whole-home models from WaterSoft’s professional product line—including High Efficiency, City Water, and Twin Legacy systems—each tailored to your home’s water source and usage.
WaterSoft® High-Efficiency Softeners
The ideal choice for New Hampshire well systems. These units remove hardness minerals while minimizing salt and water use—achieving up to 4,000 grains of hardness removal per pound of salt. Each model uses an ISOBAR™ 4 valve with adjustable cycles and on-demand regeneration for superior efficiency.
WaterSoft® City Water Softener
Perfect for municipal water customers who want softer water and cleaner taste. This system not only removes hardness but also reduces chlorine and chloramine using replaceable carbon media. It’s a great whole-home solution for better-tasting, odor-free water.
Every installation is custom-sized to your home’s needs, ensuring optimal performance without wasted salt or water.
Choosing the Right Size Water Softener System
A properly sized softener is key to long-term performance and efficiency. GSMS determines the right size by assessing:
- The number of occupants in your home
- Total plumbing fixtures and water use patterns
- Water hardness levels from your certified test
We calculate usage in grains per gallon to match the resin tank capacity and regeneration frequency to your lifestyle. This ensures your system regenerates only when necessary—maintaining peak performance while conserving water and salt.
If a softener is undersized, it regenerates too often and wastes salt. If it’s oversized, it may not cycle frequently enough to stay efficient. GSMS balances both for a precise fit that protects your home and budget.
Built for Water Efficiency
Our WaterSoft® systems are among the most efficient in the industry, making them a smart choice for both city and well water homes in New Hampshire.
- Low-Regeneration Water Use: Backwash cycles are designed to use minimal water while fully cleaning the resin bed—ideal for septic systems.
- On-Demand Regeneration: The system regenerates only when needed, not on a timer, saving thousands of gallons each year.
- High-Efficiency Salt Use: Removes up to 4,000 grains of hardness per pound of salt, drastically reducing waste.
- Treated-Water Refill: Uses softened water during brine refill, preventing internal scaling and extending component life.
- Efficient operation means cleaner water, less salt, and lower water bills—all while keeping your home’s plumbing protected.
Smart Pairings for Complete Water Quality
Sediment Prefilter
A sediment prefilter protects your softener and plumbing from sand, grit, and fine debris that often come from private wells. It’s the first line of defense against buildup and helps every water treatment system last longer.
Reverse Osmosis System
For crisp, clean drinking water straight from the tap, GSMS can add a reverse osmosis system in your kitchen. It removes dissolved solids, chlorine, and contaminants that a softener alone can’t address.
Iron or Manganese Filtration
If your certified water test shows high iron or manganese levels, we can integrate targeted filtration for these minerals. This prevents staining, metallic taste, and odor issues while protecting your softener and fixtures.
UV Purification
Homes with private wells often benefit from UV disinfection, which neutralizes bacteria and microorganisms without using chemicals. It’s a simple, effective way to ensure safe, clean water for your entire household.
GSMS often pairs a sediment filter with every whole-home installation to safeguard your investment and keep your system running efficiently.
