Once the machine is started and begins pushing air through the system, drain lines are opened to our lakes until air blows out through the pipe. Once the drains are closed, the staff turn on heads using our irrigation control boxes which are located on about every other hole. Each box controls one specific set of heads. Directly above the red wires are small toggle switches which are turned on until air begins to come out of the head.

In the final picture below, Lady Bug is challenging the head to a dual. Once air comes out of the head, the head is turned off and the next head is then activated.
