Don’t be fooled by this beautiful Colorado temperature today. We are in the Fall season. According to the weekly weather forecast, snow is on the horizon for late this week. Have you winterized your sprinkler system yet?
So, why is it so important to winterize (or Blow-out) your sprinkler system? It will increase the longevity of your sprinkler system.
Draining some water out of the system is not enough because the remaining water can freeze, expand and crack the PVC piping from fitting to fitting. If your system has polyethylene pipe, although this type of pipe is more flexible and can expand under pressure, you are taking a great risk by leaving water inside as it could freeze and rupture the pipe walls. It is simply not prudent to leave water to freeze in the backflow assembly as it will damage the internal components and crack the brass body.
