The whole water system

At Water Doctor of Washington, we understand that clean water is essential for maintaining good health. That's why we started out as a water treatment company. However, we quickly realized that we were only addressing half of the problem. Pipes, appliances, and fixtures also play a critical role in ensuring that you have access to clean, safe water in your home. That's why we expanded our services to include plumbing as well.

With our combined expertise in water treatment and plumbing, we are equipped to take care of your whole home water system. On our website, you'll find information and resources that are color-coded for your convenience. Pink indicates water treatment content, while orange represents plumbing-related information. If you are a commercial or business client looking for assistance with your plumbing or water quality needs, we offer a dedicated Business Solutions section. This section is highlighted in grey to indicate business solutions content. We hope this helps you find the information you need quickly and easily. Thank you for considering Water Doctor of Washington for all your water treatment and plumbing needs.
