Highlights
  • Hard water contains many magnesium and calcium ions.

  • Water with 0–60 milligrams per liter is considered soft.

  • Soft water boils faster because there’s less mineral content.

  • Soft water can make for more tender food, including baked goods.

You might have noticed spots and streaks on your glassware and chalky residue on your tea kettle. These are sure signs you have hard water and you realize you might need to invest in a water treatment system. But first, you want to make sure softening your water won’t ruin your cooking. Read on for a few reasons why transitioning from hard to soft water might actually improve the dishes and drinks you turn out. 

1. Everything Might Taste Better

In general, hard water contains many magnesium and calcium ions. Water with 0 to 60 milligrams per liter (mg/L) is soft, 61 to 120 mg/L moderately hard, 121 to 180 mg/L hard, and more than 180 mg/L very hard.

Since traditional water softeners remove these minerals and replace them with (softer) sodium and potassium, soft water tends to be slightly saltier and, as a result, more flavorful.

For anyone on a low-sodium diet, though, they’ll probably want to choose a salt-free water treatment system, such as a water conditioner or reverse osmosis water filter.

2. Dishes and Glasses Will Look Cleaner

Goodbye, spots and dull streaks (otherwise known as limescale) on your glassware and other dishes. With hard water, minerals build up on your serving pieces. Once you soften water, you’ll be free of that residue.

3. Water Will Boil Faster

Thanks to its high mineral content, hard water has a boiling point one or two degrees higher than soft water, so it takes a bit more time to come to a boil. Each time you cook water for pasta, rice, or tea, you’ll appreciate your decision to hire a water softener company near you

4. Appliances Will Last Longer

Mineral buildup can clog pipes and the parts of your water-using appliances, like coffee makers, tea kettles, and dishwashers. Converting from hard to soft water will likely boost the longevity of your large and small appliances. 

5. Food Will Keep Its True Colors

“Hard water is alkaline and can cause color changes in potatoes, rice, and onions,” says food science writer Shirley O. Corriher in “Cookwise.” Think cream for potatoes and yellow for rice and onions. Soft water may help keep your foods their intended color for a more aesthetically pleasing presentation.

6. Food Will Be More Tender

The calcium in hard water can make food firmer as well. “Green beans and some other vegetables can become so tough when cooked in hard water that they are inedible,” says Corriher. Soft water may make your produce easier to chew.

However, this con can also be a pro when it comes to fruits and vegetables that lose their shape, she explains. “Calcium compounds are sometimes added to tomatoes during processing to keep them firmer and prevent loss of shape. For the same reason, calcium is sometimes added to fragile fruits like raspberries when they are processed.” 

7. Your Baking Could Improve

Hard water can make baked goods tougher since minerals tighten gluten, which is a wheat protein. Treat your water, and get ready for fluffier bread, muffins, and scones. Yum!

What’s the Best Way to Get a Water Softener Installed?

If you're ready to enjoy better-tasting water at your home that enhances your culinary skills while also keeping streaks off your dishes, you have a few decisions to make. Installing a water softener isn't an overly complicated project. However, it does require your home to meet certain conditions. Here's what you need to know about how to install a water softener at your home.

Electricity

You'll need to have an electrical outlet available for your new water softener. A standard residential water softener operates on a 120-volt outlet with a 24-volt transformer. If you don't have an outlet available, you'll need to call in a professional electrician to help make an upgrade.

Drainage Access

Water softeners cycle through large amounts of water each day. You'll need to position your softener near a drainage area to accommodate capacity. For this reason, water softeners are always installed near:

  • Floor drains

  • Sump drains

  • Drain pipes

  • Basins

When installing a water softener, it's essential that you follow all local codes. Drains connected to water softeners can usually run several feet above the appliance. Alternatively, drains can run horizontally for up to 30 feet.

Centralized Location

A water softener should be installed in a centralized location in your home for maximum efficiency. This usually means a basement or utility closet. Homeowners typically place water softeners in close proximity to water heaters and other treatment systems. When setting up an "order of operations" at your home, this is the order your protocol for water treatment should follow:

  • Sediment treatment/filtration

  • Water softener

  • Water heater

This setup ensures that high-quality water will be coming from your faucets. It also helps to increase the efficiency of your appliances. By keeping your water softener in a centralized location, you may actually be prolonging the life of all of your water-treatment appliances.

Professional Installation

Water softeners come with instructions that can be followed for DIY installation. However, going in without some background knowledge can be overwhelming. In addition to learning the step-by-step process for how to install a water softener, homeowners should be prepared to tackle the challenging plumbing and electrical implications that go along with installing a softener.

First, a homeowner will need to set up a 120-volt grounded outlet with circuit-breaker protection. Additionally, it's necessary to connect the water softener at the point where the water source enters the home at a maximum rate of 125 PSI. Professional water softener installation cost ranges from $200 to $6,000.
