Backflow testing is the process of checking a backflow prevention device to ensure it’s working properly. These devices stop contaminated water from flowing backward into the clean water supply. In Gig Harbor and across Washington, annual testing is required to protect public health.
If you have an irrigation or sprinkler system, it’s likely connected to your main water supply. Backflow testing ensures your system doesn’t allow fertilizers, soil, or other contaminants to flow into your drinking water. We test these assemblies to confirm they’re preventing any reverse flow.
Washington state law requires annual backflow testing to prevent cross-contamination. It’s a safety measure that protects both your property and the broader public water system. Many cities, including Gig Harbor, enforce this regulation through utility providers.
At OneGard, backflow testing starts at just $55. Pricing may vary depending on the type of device and location, but we always offer transparent quotes up front. Call us today for a quick estimate.
Most backflow assemblies need to be tested once per year to stay in compliance with Washington state regulations. We’ll send you reminders and handle the paperwork so you never miss a deadline.
