Do You Need A Water Softener? 8 Signs That You Do

Have you ever wondered if you needed a water softener?

Maybe the look and texture of that fluid as it flows from the faucet just doesn't look right to you. Or maybe the taste is a little off-putting. Or maybe your water seems perfectly fine, but you heard there is something called a water softener and now you're wondering frantically if you need one!

Well, there are a few easy ways to find out if you need a water softener or don't need to worry about it at all. 

What Is A Water Softener And What Does It Do?

A water softener is an appliance that hooks up to the point where the water comes into the house and makes the water ... you guessed it ... softer!

But what is “soft” and “hard” water? The hardness or softness of water is determined by the mineral content in terms of calcium and magnesium. More of these minerals means “harder” water. The water softener does its job by removing calcium and magnesium from your water and replacing it with potassium or sodium.

Do You Need To Have A Water Softener?

You are not required to have a water softener for your home appliances, but having one could make them work better and possibly improve the look and quality of your water.

Water at a certain hardness may not taste or smell as good as softer water, and can potentially damage your home appliances and cause health defects. So, you may not technically “need” one, but if you have hard water, it still might be a good idea. Hard water can muck up a number of different important parts of your home such as sinks, toilets, showers, bathtubs and washers.

At What Hardness Is A Water Softener Needed?

The water hardness level that may warrant having a water softener is generally 7 grams per gallon of calcium and magnesium (GPG) or 120 milligrams per liter (mg/L). Don't know these stats off hand? Of course you don't – who would?

To initially see if you may have hard water, simply fill a glass and look at it. If there’s a distinct lack of fluffy bubbles and the water appears cloudy and/or milky, your water is probably too hard. To find out exactly how hard it is in terms of mineral GPG, order a home testing kit online or pick one up from your local hardware store.

Signs You May Need A Water Softener

Beyond just looking at your water, there are other signs to look for that might mean testing for hard water and ultimately installing a water softener. Here are a few things to keep an eye out for.

1. Scale Buildup

If you see a white chalky substance on your faucets, this could be from limescale, which consists mainly of calcium carbonate (CaCO3). If it builds up, it can harm faucets and other components of your house that your water runs through. For example, scale buildup can seriously shorten the lifespan of your appliances by getting into the gears the gears.

2. Visible Staining

White stains on your shower, sinks and other places you water runs can be signs of hard water as well. The long-term solution is, of course, a water softener, but short-term solutions to this staining include cleaning with vinegar, bleach or detergent.

3. Faded Laundry

If the colors of your favorite clothes seem to be fading more quickly than they should, this could be a sign of hard water. In addition, hard water can make them smell a bit not-so-fresh.

4. Dry Skin And Hair

High levels of hard minerals can also mess with the hydration and pH balance of your skin and hair. The most common side effect of this is dryness. If you're feeling itchy or having a bad hair day, it could be your water.

5. Fragile Glassware

Hard water can cause glassware in dishwashers to become brittle and abrasive, and therefore easier to break. It can also cause staining on the glassware. These effects come from the calcium and magnesium levels being too high and the effect that has on glassware.

6. Constant Plumbing Issues

Limescale buildup doesn't just affect appliances and faucets, it can also damage steel pipes and lead to leaks and water damage. Copper and PVC pipes are more resistant to scale buildup, so if you have those types of pipes, you’re in better shape when it comes to hard water. If not, hard water can result in frequent plumbing repairs that can be costly and affect the value of the home.

7. Malfunctioning Water Heater

Excess sediment in your water heater can absorb the water heat and accelerate the scale buildup that can cause malfunctions. In addition to testing for hard water, make sure you have your hot water heater maintained regularly.

8. Higher Utility Bills

Scale buildup doesn't just damage pipes, it can clog them, too. When this happens, the system has to work harder to push water through, raising energy costs. So, investing in a water softener can help lower your electric bill.

FAQs About Needing A Water Softener

Now let's look at what people wonder about the most when it comes to needing a water softener.

How Big Of A Water Softener Do I Need?

The size of a water softener will depend on the number of people in your home and how many gallons of water are used each day.

Do I Need A Water Softener With City Water?

Water quality can differ from city to city, and the best way to know is to get your water tested. Keep in mind that rural homes are more likely to need water softeners.

Should I Get A Water Softener Or Conditioner?

The difference between a water softener and a water conditioner is that the conditioner will alter hard water minerals, but not remove them, like a water softener does. Because of this, water softeners are more efficient at preventing scale buildup.

The Bottom Line: Is A Water Softener Necessary?

If your water is hard, it makes sense to get one and start enjoying tastier, clearer water that won't harm your home. Now that you have water softeners mastered, check out some more homeowner tips in our Homeowner Guide.
