Air Release Valve is a valve that is used to remove / enter air into the piping system. When the pipe is empty and vacuum (no air) the pipe will shrink and wrecked due to pressure from outside the pipe. To prevent this, the air needs to be put back into the piping system when the pipe is empty using the Air Release Valve.
