Backflow testing
Backflow prevention assemblies keep drinking water clean. Here is what backflow is, who needs testing, and what to expect.

Water in a plumbing system normally flows one way: from the public supply into a building. Backflow is when that flow reverses and water from a pipe, irrigation line or other source is pulled or pushed back toward the drinking water supply.
A backflow prevention assembly is a device installed on the line to stop that reversal and keep contaminants out of the potable water.
Why testing matters
A backflow device has moving parts, and it only protects drinking water if those parts work. Testing confirms the assembly is doing its job. Because devices can wear over time, testing is often required on a recurring basis.
| Property type | Typical situation |
|---|---|
| Commercial properties | Typically need testing of their backflow assemblies. |
| Irrigation systems | Commonly have an assembly that needs testing. |
| Some residential setups | Certain homes have devices that require testing. |

How a test works
A technician connects testing equipment to the backflow assembly and checks that its internal valves hold and close as they should. The results show whether the device is protecting the water supply.
Since many locations require testing on a recurring basis, results are generally recorded so you can show the device was checked. Ask what your local water authority needs.
If a device fails
A failed test means the assembly is not reliably protecting the drinking water. The device typically needs repair or replacement and then a retest to confirm it passes. Call us and we can talk through next steps for your situation.
FAQ
Why does backflow matter for drinking water?
Reversed flow can carry contaminants into the potable supply. Prevention assemblies are there to stop that.
How often does a device need testing?
It is often required on a recurring basis, but the schedule depends on local rules, so confirm your requirements.
Does my home need a test?
Some residential setups do, such as those with certain devices or irrigation. Ask us if you are unsure.
Please confirm local requirements. Testing rules and schedules vary by water provider and municipality, so check with yours.
