"Damian F. Did a fantastic job at presenting us the benefits of living in a household with filtered water. He was very professional yet personable and explained in great detail of what Kinetico is all about. I would recommend him for every house owner interested in purchasing or even learning what water softener systems do and what they provide."

"The plumbers from Superior Plumbing were excellent. They replaced and rerouted water pipes, changing from galvanized to copper pipes. The sewer lines in our house were repaired. They also replaced an aging hot water heater. The technicians arrived on time, worked diligently through the day, and were efficient. We added on the sewer repair which added an additional day. All work was completed within four days. I am impressed with their knowledge and workmanship. The technicians were tidy and removed all our old materials including the hot water heater. I would recommend Superior Plumbing and Drainage Co without hesitation."

"Our water bill doubled within the last year.  They came in and replaced a flow valve in our toilet.  That fixed the problem.  They were very responsive and appeared to be very knowledgable.  I will definitely use them again."

Water Softeners questions, answered by experts

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.

Softened water prevents scale deposits, reducing appliance wear, leading to energy savings and longer-lasting household fixtures.

Some shower water softeners are effective, but this isn’t always the case. Most shower filters only filter out chlorine, not hard minerals like calcium. Other shower filters can't handle the demand in homes with very hard water. It's also important to change the filters on your shower filters. Failure to regularly swap out old filters will make the filter ineffective over time. 

No, hard water isn’t dangerous. The added calcium in hard water can contribute to good bone health. However, it can also cause dry skin and hair. If you have dry skin or hair, consider using a water-softening system to help minimize the minerals in your water. Plus, these systems can also add some sodium to your diet. 

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.
