"John was Great!!! Our first appointment had to be cancelled due to unforeseen circumstances, but John communicated the issue immediately which was much appreciated, and set new appointment. When John came arrived on time (A+) Professional and listened to my idea/suggestion (A+) Did the job in less than the estimated time (A+) Cleaned and REPAIRED the wall area which I didn't expect (A+) Price was 1/3 of what others wanted to charge. Definitely, recommend NorCal Water Treatment to others, and will be rehiring for future plumbing projects/issues. I'm real BIG on customer service/professionalism and John is "The Man!""

"Jared showed up and wasted no time in doing two things at once (draining the hot water heater and repairing a small fireplace gas leak). He educated me a little on what he was doing which is always helpful. He was also careful to keep his booties on, so as not to ruin the shiny wood floors. Highly recommend based on this experience."

"I have been a Moore Home Services customer for well over 5 years. They have always treated me as a valued customer from Customer Service Team to the Technicians. The Moore team is professional, friendly and extremely knowledgeable. They communicate problems and work to be done in simple layman's terms. Technicians Marcos Sosa and Sebastian fixed my clogged sink that now works great. They were even able to come earlier than scheduled. As a senior citizen, living on my own, this made my day. Thank you Team Moore. Cindy"

Water Softeners FAQs, answered by experts

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.

Some municipalities require the installer to hold a plumbing license, some mandate a permit and an inspection, and others require both. In some areas, no special permit or license is needed at all.

To determine the rules in your area, you can contact your local building department or consult a local water softener installer or plumber.

It’s not a good idea to oversize your water softener. Doing so will mean the tank doesn’t get full, which can lead to channeling. This leads to a large portion of the resin beads not being utilized and the beads at the bottom of the tank being overused. Over time, this will reduce the efficiency of your system, not to mention that the upfront cost of an oversized softener is unnecessarily high. If you have a timed regeneration cycle rather than a demand-based one, you’ll also spend far more on replacing salt than you need to.

Replacing a water softener costs $200 to $6,000, depending on the capacity of the water softener, the type of water softener, and the amount of people living in your home. An ion exchange water softener is the most common type and costs $500 to $3,000. Water distillers, which cost $1,200 to $4,000, and dual-tank models, which cost $1,000 to $5,000, are definitely pricey, but they offer more filtration or capacity, respectively.

Yes. To get soft water, you can install a water softening system, which will replace the calcium and magnesium ions in the water with sodium or potassium ions. Water softeners cost anywhere from $200 to $6,000, depending on the size and complexity of the system. You can either install a water softener for the whole house or just at your shower heads. If you’re sensitive to sodium or potassium, you can install a salt-free water conditioner.
