"Gus at Pro Bright went above and beyond on a Sunday to detect and repair our master bedroom ceiling leak. With water to the house turned off at the street we were desperate to find a contractor who could respond right away. Other contractors offered appointments Monday or Tuesday. Gus responded that he could be here in 2 hours to repair the leaking pipe, but could have Jeff, his water mitigation project manager here within 30 minutes to assess the water damage. These guys were both so professional. They shared the process, timeline and costs, and were prepared to start right away. They promptly moved my disabled husband and his adjustable bed to another room away from the work area assuring his comfort and safety. Gus repaired the overhead leak and turned the water back on. Jeff scheduled the water mitigation process to begin first thing Monday morning. We are especially grateful for the kindness these 2 professionals showed us in our time of need."

Water Softeners FAQs, answered by experts

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

You should not use a water conditioner with a water softener because a water conditioner changes the chemistry of the water and causes the ion exchange in a softener to be ineffective. Choose a water softener if you have hard water or well water, and use a water conditioner if you need to remove certain contaminants.

A lower-end water softener would cost around $900, not including installation. Each home has different requirements, water hardness, and number of inhabitants, so there’s a huge range in pricing—$600 to over $6,000. The average water softener repair bill is around $500, meaning it’s a much better option to repair any issues and only replace your softener if absolutely necessary. 

The average cost to install a water softener, including the system and labor, is approximately $1,500. However, the total price can range widely from $600 to $6,000. For some complete systems, the cost may be between $800 and $2,500. Labor for the installation typically costs between $150 and $1,000.

The final price is influenced by several factors, including:

  • System type, capacity, and complexity

  • Home size and household water demands

  • Water hardness levels

  • Accessibility of the installation site and the extent of plumbing work required

  • Whether new electrical work is needed

  • The professional hired and any local permit costs

Most experts agree there’s not much difference health-wise between hard water versus soft water. That said, hard water is more likely to cause skin dryness and issues that go along with it, like an itchy or flaky scalp. Hard water can also decrease the life span of your household appliances and make it more difficult for soap to do its job.
