Winter Is On Its Way

Every year, before the first freeze, the ritual of irrigation “blow out” becomes the priority for all irrigation systems in Toronto and areas as it is only a matter of time before the frost level extends below the depth of the installed piping and freezes your system.

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 from fitting to fitting. Polyethylene pipe (Flexible, black pipe) is used in many freezing climates. Although polyethylene pipe is more flexible and can expand under pressure, water left inside could freeze and rupture the pipe walls.

Freezing water in the back-flow assembly will damage the internal components and could possibly crack the brass body. To minimize the risk of freeze damage to your irrigation system, you’ll need to “winterize” your irrigation system.

Irrigation systems in areas where “winterization” is mandatory are installed using one of three types of water removal in mind: manual drain, auto drain, or blowout. If you don’t know your system type, it would be best to use the blowout method.

At the very minimum you will need 185 cfm’s to effectively remove all the water in a residential irrigation system.  Rental companies will have larger systems capable of producing this much air but it will set you back 300$ to $400 a day, and in that case its cheaper to have us do it for you.
