It is important to winterize your sprinkler system to prevent freeze damage to the vital components of your system. Sprinkler blowouts include blowing high pressure air through the vacuum breaker, valves and lines of your sprinkler system to remove all water so it doesn’t freeze during the winter months.
When water freezes, it expands, causing pipes and fittings to burst and break. A blowout includes blowing air out of the lines and back draining the vacuum breaker into the house. This ensures that no water is left in the system to freeze and potentially cause costly major damage to the system or flood your basement.
