Crystal King Water Conditioning Company Inc. was incorporated in 1976 based in Concord and Modesto, serving the Bay Area and Central Valley. Then expanding in 1993 to the Sacramento Area acquiring the Rainsoft Dealership from the retiring owner. During the last 20+ years we have closed the Concord and Sacramento offices, consolidating the staff and business operation to one office in Modesto.

We started out as a Rainsoft Water Conditioning Dealer, proudly becoming one of the most successful and respected dealerships in the Country, always rated at the top in customer service. Today, excellent customer service is still our claim to fame.

During the last 47 years we have installed and serviced water treatment equipment to almost 12,000 happy customers. We now are proud to represent, sell, install and service Charger/Clack softeners as well as Impact Reverse Osmosis systems.

Finally, we are especially proud that one of the original owners, Michael L Brady is still in charge and runs the operations on a daily basis.

What People Are Saying About

Crystal King

“As a long term customer of Crystal King Water since 2003, I can attest to their professionalism and great work which they consistently provide. I can always count on Larry to remind me yearly that it is time for our annual filter maintenance. Crystal King Water is a company which we trust, rely on and recommend.”

Juan N., Lodi

“We had a Crystal King Water Conditioning system installed over 24 years ago. The reverse osmosis and softening has provided us with safe, clean, contamination-free, soft and wonderful-tasting water. Water that is hassle-free for us. The Crystal King staff are all courteous, friendly and professional. They just do what they say they are going to do, which is unusual in business today. We give them an unqualified recommendation for any water purification needs.”

Clay & Anita A., Modesto

“I’ve used Crystal King Water for over 24 years. They installed our under sink system and softener in the back yard. They schedule me for my yearly inspection and fix what is needed. We would never trust any other company to handle our water treatment needs.”

Dan & Cathy S., Modesto

“I have been a customer with Crystal King Water Treatment for the past 22 years and I have always received excellent service from their team. Whenever I have a question, I can call them and receive an expert knowledgeable reply. The customer service I receive whether via telephone or in-person from a technician is superb. I have my soft water system serviced annually and appreciate the technician checking all the components and providing me a written and verbal report. If a part or parts are needed, I find their pricing to be very fair. Finding a reputable soft water treatment company is not an easy task and I am so glad that I found Crystal King and would highly recommend them to anyone looking for a soft water treatment company.”

Gary H., Tracy

“I’ve used Crystal King for over 15 years. They installed my under the sink system and my salt system in the backyard. They schedule me for my yearly inspection and fix what is needed. Buy what I like best is today, when my painters or pool guy turned off my salt unit by accident and I all of a sudden had hard water. I turned it on and needed to re-enter data that I did not have. On a Saturday I called and found someone in the office. They walked me through the whole procedure and go me back on line. With most companies this would have been a call out and big bill. These are good people, they so far have proven themselves reliable and honest and dread thinking of they day they decide to wrap it up and quit the business, I will be hurting if that day comes.

As a small business owner I strive to have the same ethics they do, and take care of my clients, as they do. It’s refreshing.

If you are thinking about a software system or water filtration system, call them.”

Echo M., Modesto

“Mike and Larry at Crystal King are great! They answer all my questions on the phone and help me with parts and ideas for my water softener and reverse osmosis system.
Thank you guys!
Keep up the good work!”

Austin P., Penryn

“I bought my water softener and drinking water system from Rainsoft on January 18, 1992. Sometime after that it went out of business or something happened and there were no other listed Rainsoft to call in Sacramento. I did not have annual service on my water systems until Larry from Crystal King called a few years later. Luckily, I did not have problems even without the annual service.
Crystal King just replaced my water softener the other day and the membrane for the drinking water system was replaced about a year or so ago. It is such a pleasure to work with Larry who calls and reminds when it’s time for the annual service! Robert and Scott are pros and explain everything without “going over my head”! I live in Sacramento and so appreciative that Crystal King services our area!!!”

L.E.W., Sacramento

“I have had a water softener and R/O that I purchased in 1993 from the Modesto Rain Soft dealer on Oakdale Rd. Aside from filter replacement I have had to replace the computer after 7 years and the membrane after 12 years. Water is soft and the R/O water taste great. I purchased my house new in 1993 and I am the only house in my court that still has the original water heater. All the other homes were replace because of a buildup in Calcium and sediment.”
