Colorado Sprinkler System Freeze Prevention

Identifying your backflow preventor
There are various types of backflow preventors on the market today, but the most common ones are:

• AVB – Atmospheric Vacuum Breaker
• PVB – Pressure Vacuum Breaker
• RPA - Reduced Pressure Assembly

Protecting your backflow preventor from freezing temperatures
(1) – This is the unprotected backflow preventor. The entire device, including exposed copper pipe is susceptible to damage from exposure to freezing temperatures.

(2) – Place an old blanket, folded towel or an old coat over the entire device, taking care to cover any exposed copper pipe as well.

(3) – Place a plastic trash bag over the device you previously covered with a blanket and tie the bag securely at the bottom. Pull the bag down to ensure copper pipe isn’t exposed at the bottom.

PLEASE NOTE: The steps detailed here are good preventative measures to take during sudden cold snaps, but freezing temperatures can still cause damage to components of your sprinkler system. Contact Swingle if your system needs repair.
