The overview

What it is, and why it matters.

Many water utilities require irrigation backflow devices to be tested every year by a certified tester, and some send reminder notices. We test check valves and relief valves with calibrated gauges, record the readings and file or hand you the report. If the device fails, we repair it with new parts and retest in the same visit when possible.

In Nashville and nearby systems, devices wear from debris and temperature swings, and one that passed last year can fail this year. We also check the installation for height, clearances and freeze protection, and combine testing with spring startup to save you a visit.
