Winterize Your System: Protect Your Investment

Every year, before the first freeze, the ritual of irrigation "blow out" becomes the priority for all irrigation systems. Some areas are more prone to freeze breaks than others, but we highly recommend that you safeguard your investment by having a professional come out and properly winterize your system. We can help.

Even if you have drained some water out of the system, the remaining water can freeze, expand and crack the PVC piping (rigid, white pipe), usually in the fittings or even worse, in the valves. Polyethylene pipe (flexible, black pipe) is more flexible and can expand under pressure, but water left inside can still freeze and rupture the pipe walls. Freezing water in a backflow assembly will damage the internal components and could possibly crack the brass body. This can be a very expensive outcome, one that can easily be avoided.

To minimize the risk of freeze damage, you'll need to "winterize" your irrigation system.

The “Blow Out” Method
WARNING! Extreme care must always be taken when blowing out the system with compressed air. Compressed air can cause serious injury, including serious eye injury, from flying debris. Do not stand over any irrigation components (pipes, sprinklers and valves) during air blow out. Serious personal injury may result! It is recommended that a qualified licensed contractor perform this type of "Winterization" method. New Leaf Landscaping is here to help.

The blow out method utilizes an air compressor with a Cubic Foot per Minute (CFM) rating of 80-100 for any mainline of 2" or less. When done properly, this method gradually introduces air into the irrigation system and eliminates as much as 80-90% of water remaining in the system. No water in the system = no freeze breaks.
