Don’t let the beautiful fall weather fool you – winter is coming, and that means it’s time to make sure your sprinkler system is ready for freezing temperatures.
The most important thing to remember is to shut off the water supply at the stop and waste valve and drain away any water left in the system. In our climate, the ground often freezes to a depth lower than the average sprinkler pipe, so if there is water left in the pipe it can freeze and expand, cracking the pipe. Then the system pressures up in the spring, the cracked pipes can leak and flood yards and homes.
Many systems are designed with built-in drains at the lowest points, so after you turn off the water supply, water will naturally drain out of the system. But it’s safest not to rely on this passive drainage; the best way to winterize the system is to use compressed air to blow remaining water out of the pipes. Some handy people can do this themselves, but if you don’t have the expertise, the equipment, and/or the time, call a qualified landscaper to do the job.
