To prepare your sprinkler for its regular maintenance during the cold seasons, the Interstate team will ensure that your system’s winterization is completed correctly. The water supply to the sprinkler system will be turned off and all of the sprinkler lines are then filled with compressed air to expel any of the excess water in the pipes. Next, we open all of the system drain valves to free any residual water. Above ground valves and devices are stopped or insulated for them to remain intact and unharmed during the winter.
