Q: Will a whole-house filter help with hard water?

• <div><p>Yes. Hard water is what causes scale buildup, and a whole-house filter provides numerous benefits beyond water softening. Any water that enters your home will go through the filter, which cleans up all water that you will use for cooking, bathing, and drinking. A whole-house water filter also blocks harmful particles like heavy metals.</p></div>

Q: Do you need a permit or license to install a water softener?

• <div><p>Whether you need a permit or license for a water softener installation depends on your location, as requirements vary significantly. Some municipalities require the installer to hold a plumbing license, some mandate a permit and an inspection, and others require both. In some areas, no special permit or license is needed at all.</p><p>To determine the rules in your area, you can contact your local building department or consult a local water softener installer or plumber. Often, only certified professionals are authorized to pull the necessary permits, and they will typically handle the entire permitting process for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use Angi&rsquo;s state licensing tool to check an installer&rsquo;s license status.</p></div>

Q: How much does it cost to replace a water softener?

• <div><p>Replacing a water softener costs $200 to $6,000, depending on the capacity of the water softener, the type of water softener, and the amount of people living in your home. An ion exchange water softener is the most common type and costs $500 to $3,000. Water distillers, which cost $1,200 to $4,000, and dual-tank models, which cost $1,000 to $5,000, are definitely pricey, but they offer more filtration or capacity, respectively.</p></div>

Q: What maintenance is required after installing a water softener?

• <div><p>Routine maintenance involves recharging the resin bed with salt or potassium, cleaning components, and periodic inspection.</p></div>

Q: How do I know if I have hard water?

• <div><p>The most accurate way to determine whether you have hard water is to purchase a <a href="https://www.angi.com/articles/how-test-your-water-quality.htm">water test kit</a> from a hardware store or send a tap water sample to a lab. But there are some signs you can look out for without professional testing. For instance, if you're consistently dealing with mineral stains on your glassware, windows, and shower doors, you're likely to have hard water. Hard water can also make it harder to lather and rinse soap, so if you're struggling to work up a good lather in the shower, hard water might be the culprit. </p></div>
