The forecast is calling for a hard freeze Wednesday and Thursday nights. If you have already turned on your sprinkler system we would highly recommend that you drain the supply lines to try and prevent any freeze damage to the copper, backflow preventer, and the manifold. Please watch this video to see the step by step process on how to do this. To turn it back on, you will simply need to reverse the process. If you cannot locate any of the appropriate turn on or shut off valves and we have serviced your property before, please call the office and we can help you locate them because we have a database with that information.
