Irrigation Backflow Freeze Prevention

Sprinkler Backflow Preventer Protection

When temperatures are at or below freezing, it’s important to protect your sprinkler system in order to avoid freeze damage. The best way to avoid freeze damage is to have your system winterized prior to a freeze.

However, Colorado is known for its rapidly changing climate. It’s important to know how to protect your homes sprinkler system in case of an unexpected freeze and your system hasn’t been winterized. To properly protect your system from freezing and causing costly damage, there are various steps you can take to get you through the night so you can properly winterize your system on a later date.

PLEASE NOTE: The steps detailed here are good preventative measures for unexpected freezes, but freezing temperatures can still cause damage to components of your sprinkler system.

  1. The backflow preventer seen in the video above, including the exposed copper pipe, is susceptible to damage from exposure to freezing temperatures.
  2. To properly protect your backflow, you want to wrap it in insulation and tape it tightly so that it remains in place. Make sure you cover any exposed coper piping during this process. If you do not have any insulation on hand and it is an emergency, you can use an old sweater, towel or blanket as well.
  3. Place a plastic trash bag over the newly insulated backflow and tie the bag securely at the bottom. Pull the bag down to ensure nothing is exposed.
