Do I Need a Water Softener: 6 Ways to Tell When It's Really Necessary

In this article, we’ll help you determine if a water softener is necessary to address hard water in your home.

By: Maggie Irish

As a homeowner, you probably have some familiarity with hard water or have at least heard it mentioned. It’s an issue that affects most homes throughout the U.S., and if left unaddressed, creates several annoyances day-to-day with more severe issues long-term. A water softener is a system that addresses hard water, but you might wonder when a system is truly needed.

Without a good understanding of these systems and your situation, you could be spending a lot of money on something that wasn’t that big of a problem in the first place. On the other hand, if you don’t buy a softener, you could be putting your health and home at risk.

In this article, we’ll discuss hard water and how to determine when you actually need a softener for your home.

What is hard water?

Hard water is water that has a high concentration of minerals, usually calcium and magnesium that’s absorbed from rocks and soil it comes in contact with. Water from a well is most likely to be hard because it travels through several layers of rock and soil, but water from the city can be hard even after being treated by your municipality.

Hard minerals in small amounts don’t pose much of a problem, but if allowed to build up can gradually lead to limescale buildup which can reduce water pressure, clog pipes, and damage appliances. Hard water also reduces the effectiveness of soaps and is damaging to your skin and hair.

How is water hardness measured?

Water hardness is measured in grains per gallon (GPG) or parts per million (ppm), which refer to the concentration of dissolved minerals in water. The scale below is how your water hardness is determined based on its GPG or ppm level, which you can see in your water quality report or a water hardness test.

  • Soft: 0–1 GPG (0–17.1 ppm)
  • Slightly Hard: 1–3.5 GPG (17.1–60 ppm)
  • Moderately Hard: 3.5–7 GPG (60–120 ppm)
  • Hard: 7–10.5 GPG (120–180 ppm)
  • Very Hard: 10.5+ GPG (180+ ppm)

How does a water softener work?

A water softener addresses hard water by using ion exchange to remove hard water minerals. Sodium is added to the softener using salt pellets that charge resin beads. The beads act like a magnet and pull the hard mineral ions from the water as it passes through the tank, then replaces those ions with harmless sodium ions. After this exchange occurs, the softened water enters your home’s water supply while the hard minerals are flushed out of the system.

How do I know if I need a water softener?

Homes that rely on well water will almost certainly need a water softener, but you may still need one even if you get water that’s treated by the city because it can still be hard after removing contaminants. The best way to determine if you need a water softener is by testing your water hardness, or you can look around your home for these common signs you need a water softener.

1. Stains on fixtures

Hard water can leave behind dissolved minerals that look like white, chalky stains on your sinks, bathtubs, and toilets. If these stains accumulate quickly and take some elbow grease to go away, it can indicate you have a serious hard water issue that warrants getting a water softener. Check for these stains, and see how long it takes for them to reappear after cleaning them.

2. Spotty or cloudy dishes

You can also see traces of dissolved minerals on your glassware, even after a cycle in the dishwasher. Inspect your dishes and you might find spots or cloudiness in their finish. Hard water can even cause etching or scratches on your dishes and weaken their integrity, making them more fragile over time. Take a look at your dishes to see if there are spots, cloudiness, or scratches after a wash cycle.

3. Scale buildup in pipes and appliances

Hard water can create scale buildup in your water supply and make it more narrow, resulting in reduced water flow. You might notice a decrease in water pressure while you’re showering or using a faucet, which can indicate a clog in your pipes from scale buildup. Limescale can also build up in your appliances like your kettles, coffee pots, dishwashers, and washing machines. Left unchecked, limescale can reduce the efficiency of your appliances and even shorten their lifespan. If you notice a decrease in water pressure or chalky spots on appliances, a water softener might be needed to prevent further damage.

4. Dry skin and hair

Does your skin or scalp feel itchy even though you just took a shower? Bad news, hard water could be to blame. Minerals like calcium and magnesium can disrupt your natural oil production, stripping your skin and hair of natural oils and causing irritation. You may notice your skin and hair are excessively dry, and your hair is more prone to breakage.

5. Faded or damaged laundry

Over time you may have noticed that your favorite clothes have lost their color or become rough. This is because hard water can strip away the life from your clothes by fading them and damaging the fabric. Hard water also makes detergent less effective, so laundry straight out of the dryer can still appear dingy.

6. Higher utility bills

According to the Water Quality Association (WQA), hard water can reduce the efficiency of your appliances by up to 48% and their lifespan by 30-50%. Have you noticed your energy bills slowly increasing? This might be because hard water has damaged your appliances, requiring them to work and use more energy than they did before. If you notice your utility bills are increasing even as your usage seems to stay the same, hard water could be the culprit. A water softener will remove hard minerals to keep your appliances running efficiently, which can save you money on utility bills.

Why do I need a water softener?

Hard water causes minor inconveniences in the short-term but major issues long-term. On a day-to-day basis, you might find it annoying to deal with hard water stains, dry skin and hair, and laundry that doesn’t come out as clean as it should. Over time, the bigger issues have more significant costs from higher utility bills, plumbing repairs, and appliances that wear out quickly or don’t work effectively.

Whether you need a softener right away, or at all, depends on the severity of your hard water and how much you’re willing to tolerate these issues. Water that’s soft or only slightly hard might not warrant getting a water softener, while water that’s moderately hard or greater can indicate you should invest in a softener sooner rather than later. Hard water issues get worse over time, so if you need a softener, it’s best to get one as soon as possible.
