Welcome to Coast Water Conditioning & Plumbing

Coast Water Conditioning & Plumbing specializes in bringing fresh, clean water to you, your family, and your workplace. Most Americans have access to drinking water, but just because water comes out of the faucet, doesn’t necessarily mean that it is as clean as it can be. All living things need water to survive, our bodies are made up of more than 75% water. Clean water is essential for good health!

Our Customer Reviews

Here's what our happy customers are saying.

★★★★★

Grant was awesome and installed our rental RO filter quickly. The monthly rental price is very reasonable after looking around at other companies in San Diego, but most importantly there are no hidden fees or tricks. Happy to keep supporting this local business and even more happy my drinking water tastes so good now.

Super fast response time,  professional, reliable, thinks outside the box when trying to troubleshoot a broken water softener that was not a typical brand they work on.   I appreciated Grant, the owners, honesty and hard work, and I know I got a good deal on a new unit.  Highly recommend!

I'm a service business owner myself and I know several plumbers but Coast Water Conditioning and Plumbing is by far the best.  Grant the owner knows what he is doing, is honest and very respectful to deal with which is a breath of fresh air. I have used them on several personal projects and highly recommend that you do to.
