What Is a Water Softener System?

A water softener system is a filtration unit that uses Ion Exchange to physically remove hardness minerals (calcium and magnesium) from your water supply. Unlike “conditioners” that only prevent sticking, a true water softener actually removes the rock-forming minerals that destroy plumbing. At National Water Service, we specialize in water softener installation that protects every tap and appliance in your home.

Who Needs Water Softener Installation?

A water softener is ideal if you:

  • Use private well water (or hard city water)

  • Have white spots on glassware and dishes

  • Suffer from dry, itchy skin or frizzy hair

  • Are installing a new Water Heater (to protect the warranty)

  • See crusty white buildup on faucets and shower heads

Water softeners are commonly installed alongside sediment filters to ensure maximum plumbing protection. Learn more about whole house water filtration here.

Signs of Hard Water in Your Home

Benefits of Whole House Water Softeners

Water softener systems offer immediate protection for your home. The primary advantage is the elimination of “Scale”—the rock-like buildup that clogs pipes and ruins appliances. Without a hardness test, you may be unaware of your water quality until your water heater fails. A system gives you peace of mind.

Total Appliance Protection

Hard water destroys water heaters, dishwashers, and washing machines. A softener extends appliance life by 30-50%.

Healthier Skin & Hair

Hard minerals clog pores and coat hair. Soft water allows natural oils to work, resulting in smoother skin and shinier hair.

Cost Effective

You can use 50% less soap and detergent with soft water because it lathers instantly. This saves hundreds of dollars a year.

Low Maintenance

Once installed, our modern systems are “set it and forget it.” They only require periodic salt refills, which we can deliver or you can manage easily.

Energy Efficient

High-efficiency softeners reduce energy waste. A scale-free water heater uses 30% less energy to heat your water.

Improved Cooking and Drinking Water

Soft water can improve the taste of your drinking water, making it more pleasant to consume. It can also enhance the flavor of food and beverages prepared with water, such as coffee, tea, and soups.

Easier Cleaning

Soft water can significantly improve your cleaning efforts around the house. Dishes will come out sparkling clean without the annoying spots and residue left by hard water. Your fixtures and appliances will be easier to clean as well, with less scale buildup to scrub away.

Is a Water Softener Good for Well Water?

Yes — A water softener is essential for Maryland & Virginia wells. Well water in our region flows through limestone bedrock, picking up high levels of dissolved calcium. This makes well water significantly harder than city water.

Typically every 6-8 weeks, depending on your water usage.

Water softener installation is complex. Incorrect sizing can lead to pressure loss or salt bridging. We recommend professional installation.
