"Bryan is awesome! He is incredibly professional. He knows what he is doing without a shadow of a doubt! Bryan even followed up with me after the install on top of stopping by shortly after just to triple check everything. Not only this but he even went out of his way after hours to answer any of my questions over the phone. If I had to summarize this review for you, I would tell you that if you want a professional that is incredibly passionate about what he does and genuinely cares about his clientele, then you need to hire St. Clair Plumbing immediately. Thank you, Byran. I toast this glass of purified drinking water to you, good sir!"

Water Softeners questions, answered by experts

The most effective way to fix hard water in your shower is by installing a whole-home water softening system. This system treats water as it enters your home, removing the minerals that cause hardness before they can reach your shower or any other fixtures. While this is the most comprehensive solution, other methods are often temporary fixes. For a more affordable and shower-specific option, you can install a water-softening showerhead or a shower filter. However, these filters are generally less effective and may not remove all the contaminants that lead to limescale and hard water stains. By implementing a water softening solution, you can expect a reduction in mineral deposits and enjoy the benefits of cleaner-feeling hair and skin.

Installing a water softener could help reduce calcium buildup in your pool if your pool has high calcium hardness as a result of hard drinking water in your home. Pool softeners work by exchanging calcium and magnesium for sodium, so if you use softened water to top off your pool, it may help keep calcium hardness from rising over time. However, it won’t lower the calcium hardness of the water already in your pool and isn’t a practical way to control pool calcium levels. The average water softener installation cost is between $200 and $6,000.

Yes, a water softener can remove scale deposits. According to the U.S. Department of Energy, after you add a water softener to your home, “gradually the softer water will dissolve limescale scale deposits and remove the problem entirely.” Installing a water softener—or water descaler—will also help prevent new scale deposits from forming.

A water softener removes minerals from your drinking water and can make your house water softer. These softeners are designed to extend the lifetime of your plumbing system while also making water safer and more palatable for drinking. Hard water, which is water with a heavy amount of suspended particles, can also cause hair damage, skin irritation, and buildup in your pipes.

Whether you need a license or permit for water softener installation depends on your location. Some municipalities require the installer to hold a plumbing license, while others may only require a permit and an inspection. In some cases, both a permit and a licensed installer are necessary, and some areas have no requirements at all. Often, only certified plumbers and electricians are allowed to pull the necessary permits. To find out the specific regulations in your area, you can contact your local building department. Alternatively, a local water softener installer or plumber will be familiar with the requirements and can typically pull the permits 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 tools like Angi’s state licensing tool to verify an installer's license status.
