Annual Backflow Testing Requirements in Washington
In Washington, backflow assemblies must be tested annually to ensure they function properly and protect the public water supply. Local municipalities and water authorities enforce these regulations to comply with state health standards.
If you have an irrigation, domestic, or fire system backflow assembly, you are likely required to have your backflow device tested once per year by a certified backflow assembly tester.
With over 30 years of industry experience, you can trust that your test is done correctly, professionally, and in full compliance with Washington regulations.
Backflow Preventers
Purpose of a Backflow Device
- A backflow prevention device is designed to protect your drinking water from contamination.
- Under certain conditions—like a sudden drop in water pressure—water can flow in the wrong direction (called “backflow”). When this happens, contaminants such as fertilizers, chemicals, or bacteria can enter the clean water supply.
- Your backflow device acts as a safety barrier, ensuring water only flows in the correct direction and keeps your water safe.
Why Backflow Testing Matters
Regular testing isn’t just a requirement—it’s essential for protecting both your property and the community.
Health Protection - A failing backflow device can allow harmful substances into the water supply. Annual testing helps ensure your system is working correctly and keeps your water safe for everyday use.
Legal Compliance - In Washington, failing to complete your required backflow test can result in:
- Notices from your water provider
- Fines or penalties
- Possible interruption of water service
Staying compliant avoids issues and gives you peace of mind.
