Why does a sprinkler system need to be “blown out” or winterized?
In this region, temperatures drop below freezing quite quickly. If a system has not been drained and there is water in the PVC and copper piping, the quick freezes can cause these pipes to freeze and burst. Also, the poly piping in the ground can eventually freeze and crack during the winter if left full of water. These cracks create “line leaks.” These leaks are often difficult to locate and cost much more to repair than simply getting the system winterized.
