Seeing These Backflow Warning Signs? Call Olympic Plumbing Technology Before It Gets Worse
First Of All: What Is Backflow?
Backflow can introduce contaminants into your home’s water supply, creating potential health risks and plumbing damage. If you notice any of the signs below, call us to schedule a service and let Olympic Plumbing Technology restore your water safety and peace of mind.
-
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.
-
Slow Draining Fixtures: Backups or slow drainage in sinks, tubs, or toilets can stem from cross-flowing water.
-
Visible Leaks or Water Around Valves: Pooled water near your backflow prevention device could signal a malfunction.

We had a sewage emergency and while remediation was happening, some sink plumbing needed to be taken care of. We called and Caleb came out and hooked up us in less than two hours. Excellent service, learned a lot from him in the process!
...some time later...
We had another small issue and Zachary S. came out in a couple of hours and got us squared away very quickly. He was pleasant, knowledgeable and effective.
