Backflow Device Freeze Protection

Backflow Device Freeze Protection

We have found that areas of the county may be subject to a freeze from time to time. Should this occur, your above-ground backflow device may freeze due to the location and exposure of the device. When this happens, you may experience no water (due to it being frozen), or damage to the device caused by frozen water that may crack or warp the brass internal parts. Therefore, the County recommends you winterize your backflow devices to protect them from a frost or freeze should it occur. A freeze usually lasts only a few hours. For this reason, you may only need to prevent the cold from settling on your device for a short period of time.

An inexpensive way to protect your backflow device would be to cover the devices with a burlap type material and cover that with black roofing felt, or material similar to that, used to protect flowers and plants from frost. There are also products available specifically designed for covering your backflow device that can be found at home improvement and agricultural supply outlets.
 
An additional way the protect your backflow devices is to find and slightly open one of the test cocks on your backflow preventer allowing a slight drip. Letting the device drip can prevent the device from bursting.  Opening a test cock will provide relief from the pressure that builds between the faucet and the ice blockage when freezing occurs.

The responsibility of protecting the backflow devices is that of the customer. Should you have any questions regarding this matter, please contact the Cross-Connection Control office at 407-665-2795.
