-
Discolored Water: Brown, yellow, or cloudy water can mean contaminants are flowing back into your clean water lines.
-
Bad Tastes or Odors: A metallic or sewage-like smell or taste is a serious indicator of cross-contamination.
-
Unusual Water Pressure Drops: Sudden changes in water pressure may suggest backflow issues or valve failure.
-
Visible Leaks or Water Around Valves: Pooled water near your backflow prevention device could signal a malfunction.

We had our 19 year old water heater go out on us and within a day Olympic came out and did an assessment and 2 days later the job is done! Jake R. did the tankless install solo along with a couple other projects and got everything done beautifully and quickly and was extremely informative and professional.

Gaige Stidham was terrific! He called to say he was coming, came on time, explained everything that he would do and the options I had in choosing the best route for my own situation. He replaced a shelving unit I had taken apart to make room for him to work on my tankless water heater.

The dispatcher answered my call on the first ring, had an emergency plumber on call, and got me scheduled. Keenon was excellent, showed up on time, addressed the problem, was professional and personable, upfront about what needed to happen, and got the job done right away.

John L. came out to our home in Tacoma and found that the water leaking up from the flooring was being caused by corroded copper pipes from the waterline. He was probably here for half an hour, but in that time had troubleshooted the issue, explained the situation, and gave us solutions — including an estimate. John was very professional yet personable. Highly recommend this company.
