First, if you are going to be away from Robson

Shown above is the main sprinkler valve.
The red handle is in line with the pipe when the water is on to the sprinkler. To shut the valve off, turn the red handle

the slots 90 degrees, now the relief valves are open. Any water left in the pipes can freeze but will cause
