"Will Melendez visited our home and confirmed an independent lab finding of hard water. He listened to our concerns and outlined options to address them. Once we decided which option to pursue, he set a date for system installation and associated electrical work, which provided by an independent licensed electrician. Nick, the installer, arrived on time and worked a full day to implement the system. His work was neat and professional. I had 3 other contractors in - all of whom received good grades on Angies List - before selecting Culligan. They had the most competitive price and provided the most comprehensive solution."

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.

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. 

Hard water isn’t unhealthy. It’s safe to drink, bathe in, and cook with. However, it can make some skin, hair, and scalp problems, such as eczema, worse by affecting the pH balance of your skin and hair. Additionally, some people don’t like the taste of hard water, but it does contain minerals that are important to your overall health, like calcium.

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.

Routine maintenance involves recharging the resin bed with salt or potassium, cleaning components, and periodic inspection.
