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.

Dylan did a great job. I am concerned about the cost to move the water heater over about 5 inches when i had already paid to have it installed.

Overall, I was very pleased with Olympic Plumbing Technology. The customer service was great.

We employed Olympic Plumbing Technology (OPT) in a previous major project: sewer piping, hookup, and septic tank decommissioning of a 72-year-old house and were very pleased with OPT’s communication, planning, and work on that project.
When we noticed some leaking water faucets, we called OPT again. Brandon (OPT) did a thorough evaluation of the water supply piping and recommended whole house piping replacement. This project proceeded quickly and brought our house plumbing up to code. Thank you, Brandon and OPT!!!
