Certified Backflow Plumbers for Commercial Facilities
At Western Mechanical Contractors, we test, repair, and install backflow prevention devices to ensure your facility meets requirements and has clean running water. A backflow prevention device ensures that contaminated water doesn’t flow back into clean water supply, which could cause poisoning and compromise water safety. Commercial facilities are required to have these installed and must test them annually. Failure to do so can result in the Water District distributing fines or shutting off water supply completely.
Backflow tests must be completed by a certified backflow plumber. If your device fails, the Water District requires a passing test typically 30 days thereafter. With such a tight deadline, scheduling repairs and re-testing can be stressful. At Western Mechanical, we provide complete backflow services, meaning we test your device, get instant pass/fail results, and can promptly start work on repairs if needed.

Start-to-Finish Backflow Services
Backflow Testing
We start with a test to validate the effectiveness of your backflow prevention device. Results are available within minutes, and we’ll let you know immediately whether the system passes or fails.
Documentation
Once testing is complete, our team submits the required documentation to both you and the Water District. In most cases, facilities have up to 30 days to complete any necessary repairs.
Repairs & Installation
If your device does not pass, we provide clear repair recommendations and can schedule the work promptly. Using the same company for both testing and repairs helps streamline the process and reduce delays.
Retesting & Documentation
Once repairs are completed, we will retest the system. After the system passes (which typically occurs on the first test following repairs), we submit the required documentation to the Water District and provide you with a copy of the results.
Because backflow testing is required annually, many of our clients continue to use our services year after year. We work with commercial and industrial properties, medical facilities, schools, restaurants, apartment complexes, and federal government buildings throughout King and Pierce Counties.

Frequently Asked Questions
What is a backflow prevention device?
A backflow prevention device prevents contaminated water by ensuring the water can only flow one way. All commercial buildings are required to have some type of backflow prevention device, and standards vary depending on the industry.
What is the purpose of backflow testing?
Backflow testing ensures the prevention device is working properly. Annual tests are required for commercial facilities and must be conducted by a certified backflow inspector.
How often is backflow testing required?
Backflow testing is required annually, and any time equipment is repaired or replaced.
What happens if your backflow device fails the annual test?
If your device fails, we provide recommended repairs based on the results, then coordinate a time to make repairs and run another test. A passing test must typically be filed within 30 days after the initial failure. We handle all the paperwork and filing with the Water District.
