DENVER (KDVR) — Colder temperatures have arrived and that means it is time to start winterizing your home.

In order to avoid costly repairs to your sprinkler system, it is important to prepare now for the winter months.

Colorado State University Extension said that when temperatures hit 32 degrees and below, water will expand as it turns to ice and that can cause pipes and fittings to burst, valves to crack, and sprinkler and pump cases to split open.

Winterizing your sprinkler system

Some sprinkler systems have different types of drainages, they can be automatic or manual.

If you have a manual drainage system, here are the steps to take, according to Home Depot:

  • Shut off the water supply to the system.
  • Then, look for the manual valves at the ends and low points of the piping. 
  • Open all the valves and drain the water from the system.
  • Make sure you also drain the backflow device.

“Some sprinklers are equipped with check valves. These devices allow water to only flow one way. If you’ve got check valves on your system, try raising the sprinkler heads. This should let water drain out of those mechanisms. Once you’ve drained the entire system, close all the valves,” Home Depot said.

If you have an automatic drainage system, here are the steps to take, according to Home Depot:

  • Turn off the water supply.
  • Briefly run one of the sprinkler heads to relieve the water pressure in the system.
  • Automatic draining should begin, clearing the pipes of excess water.

“You may still need to drain the water between the shut-off valve and the backflow device. If the sprinkler heads are equipped with check valves, empty them separately,” explained Home Depot.
