What happens during an irrigation backflow test?

What to expect

During irrigation backflow testing, a certified technician checks the backflow prevention assembly on your sprinkler system to make sure water is flowing the right way and that contaminated water cannot move back into your clean water supply.

At Dallas Landscape & Irrigation, the process is typically straightforward:

• The technician locates the backflow device and inspects it for visible damage or leaks.
• Special test equipment is connected to measure pressure and verify each valve is working correctly.
• Results are recorded to confirm the device passes or fails testing requirements.
• If any issues are found, the technician explains the problem and next steps.

If the device passes, you have documentation showing the system is operating properly. If it fails, repairs may be needed before it can be retested. This testing helps protect your irrigation system, your household water supply, and your property.
