Step 1 – Turn off the sprinkler system at the source.
Step 2 – You will need a flat head screwdriver, open valves on backflow device, leave them at a 45-degree angle. (as shown in the diagram to the left) The screwdriver is for the smaller valves on the side. Insert the screwdriver into the slot, and turn to a 45-degree angle.
Step 3 – Run the clock through a cycle. Once completed turn the clock off.
Step 4 – Open any drains. There should be a drain in the basement, and possibly
a drain in the valve box.
Step 5 – Cover backflow device with a blanket/towel and place a trash bag over the device to keep it dry and insulated.
It is recommended that every year, before the first freeze you have your sprinkler system winterized. This process includes blowing compressed air through your sprinkler system to purge the system of water. This process will make the system free from potential freeze damage.
The above diagram and steps are designed to assist you in the event of an early freeze. The backflow preventer is the most susceptible to freeze damage early in the fall. This process is only designed as a temporary preventive process to protect your system from freezing temperatures, it is highly recommended that you have your sprinkler system blown out professionally. Our service is guaranteed against freeze damage. Once we have completed our winterization service, if the system were to freeze and break, we will repair it for free.
