When should I turn on my sprinkler system in the spring?

April is the month that most people in Durango turn on their system. If you have an above ground device such as a backflow preventer or some PVC piping, it may be wise to wait until later in the month. If you have no exposed piping, and we get an early, warm spring, the end of March can work. The higher your elevation, the later you should turn your system on. Depending on the weather you may have to wait until the end of May.
