Backflow Testing

Certified Backflow Testing

To provide a more complete service to our customers, TruSeason is certified with the State of Idaho to conduct Backflow Tests. Idaho rules for Public Drinking Water Systems (IDAPA 58.01.08) and the Idaho Bureau of Occupational Licenses (IBOL) require that all irrigation systems connected to the public drinking water supply be equipped with a backflow prevention assembly. A backflow prevention assembly is a system that prevents potentially contaminated water from getting into potable water supplies due to backflow. This is most known with irrigation systems since we have fertilizers, pets, and other potential contaminants on our lawns. The annual backflow test performed by a state licensed backflow technician, allows us to determine that the backflow system is operating correctly, if the system fails it will typically start leaking to indicate there is an issue. All backflow assemblies will incur additional testing costs if initial test fails.


This device must be tested when installed and annually thereafter by a State certified Backflow Assembly Tester to verify that it is operating properly. This is an annual required test for your backflow assembly by the state. We do not enforce the law, we are simply the testers that report the results and can conduct repairs if necessary.


Backflow is the reversal of water flow through pipes due to siphonage or back pressure. A State Certified backflow device is required by law and protects your drinking water by preventing siphonage from your lawn back into your domestic water supply. If backflow occurs in your irrigation system, it can cause water contaminated with chemicals or even animal wastes to be suctioned backwards into your drinking water.

State Certified

At TruSeason, we have certified backflow assembly testers on staff that have completed a rigorous training program and are certified to inspect, test, and repair all backflow assemblies and devices. We provide Idaho State certified backflow testing, repair and installation services to the North Idaho area.
