Get matched with top water softener pros in Sullivan, IL

Q: How far away does a tankless water heater need to be from a softener?

• <div><p>A tankless water heater should be at least 10 feet away from a water softener, although the pros you hire for water softener installation can help you determine the correct distance. These two units need to have some distance between them to prevent hot water from the tankless water heater from flowing backward into the water softener when it runs a regeneration cycle.</p></div>

Q: Can you have both a water softener and a water filter?

• <div><p>Yes, you can have both a water softener and a water filter. In fact, some manufacturers sell dual water softening and filtration systems that treat hard water and provide clean drinking water. If you&rsquo;re unsure about what you need or want to discuss your options, reach out to a <a href="https://www.angi.com/nearme/install-water-softener/">local water softener installation company</a>.</p></div>

Q: What does hard water feel like?

• <div><p>Hard water doesn&rsquo;t hurt, but it might feel more abrasive, especially if you have sensitive skin. It&rsquo;s also about how your skin feels <i>after</i> bathing. You might feel as though you have a sticky film over your body because you do&mdash;it&rsquo;s all that soapy residue left behind because the hard water can&rsquo;t rinse it off completely.</p></div>

Q: What are some benefits of a water softener?

• <div><p><a href="https://www.angi.com/articles/water-softener-benefits.htm">Water softeners have many benefits</a>. The most important one is converting previously hard water&mdash;water with too many minerals&mdash;to more usable, easier water. When we say easier water, we mean water that&rsquo;s easier to digest, less harsh on skin and clothes, and builds up less in the water system. Softer water may lead to lower energy costs and will extend the lifespan of all appliances that use water. </p></div>

Q: What are the side effects of drinking hard water?

• <div><p>Drinking hard water is not known to have any negative health impacts. Using hard water can lead to dry skin and hair, and the minerals in hard water can build up in pipes, faucets, and appliances. Hard water is more of a threat to your plumbing than it is to your health.</p></div>

"I used this service over a year ago. I don't remember the person who did it. I would remember if there was anything I didn't like about them. But because of the time that has passed, I can say that has made a big difference in reducing the amount of seepage in my basement. If I even ever see any more seepage, I would call them to fix more cracks. Forget all the expensive water proofing. Get these guys to identify the worst cracks and fix them!!

"Not good. The water leaks had caused black mold that had to be repaired. When repairs were completed 3 months later, the valves still leaked from the stem when turned on. It was past 60 days so I had to pay another $100 service fee to have the water leaks fixed. He tightened the packing and quoted $350 to replace the valves. Sheesh."
