Fall sprinkler blowouts (winterization)
Compressed air clears every zone, the backflow preventer and the supply line so nothing is left to freeze.
The short answer
PWW Services installs, repairs, starts up and winterizes lawn sprinkler systems in Grande Prairie, Clairmont, Sexsmith and the County of Grande Prairie. In this climate the job that matters most is the fall blowout: water left in the lines freezes, and cracked pipe, valves and backflow preventers are the usual result. Book it before freeze-up.
Spring start-up
Slow pressurization, a zone-by-zone check of heads, valves and the controller, and coverage adjustments get the system ready for the growing season.
Sprinkler repairs
We repair broken or sunken heads, leaking valves, cracked lateral lines, controller and wiring faults, and zones that won't turn on or off.
New irrigation system installs
The work starts with a site walk and zone layout matched to the lawn, beds and water pressure, followed by controller set-up and a walkthrough.
Why winterization matters in Grande Prairie
The January mean is −13.9 °C, the record low is −52.2 °C, and measurable snow can fall from September through May. A sprinkler system must be blown out before sustained freezing so water is not left in lines, valves or the backflow preventer.
