Installing Air-Release Valves
As our Tazewell Water main project is nearing the finish line, we are installing some ARV’s where they are needed.
💧 Air Release Valves (ARVs)
* Releases trapped air from water mains.
* Prevents air pockets that can restrict water flow.
* Helps prevent water hammer and pressure fluctuations.
* Allows water mains to fill properly during startup.
* Protects the pipe from damaging vacuum conditions.
* Typically installed at high points in the water main.
Properly installed ARVs help keep water systems flowing efficiently and protect the integrity of the main.
These are especially important in the constantly changing terrain of East Tennessee!
