720A Bonnet Repair Kit for Pressure Vacuum Breaker

The bonnet repair kit contains all necessary components to restore the functionality of the 720A backflow prevention valve, which has been damaged by winter frost. Made of cast brass, the bonnet is paired with a black plastic canopy.

Designed to fit 1/2 inch to 1 inch 720A models, this Bonnet Repair Kit is compatible with 1/2-inch, 3/4-inch, and 1-inch 720A Bonnet Repair Kits. The 720A pressure vacuum breaker assembly is specifically crafted for installation on potable water lines, safeguarding against the back-siphonage of contaminated water into the potable water supply.

The package includes a bonnet, canopy, and canopy screws. In cases where the canopy is cracked or broken, it is typically due to the valve freezing and distorting the bonnet. In such instances, both the canopy and bonnet must be replaced to ensure proper alignment of holes. Additionally, a plunger kit may be required if the upper plunger is damaged.

To prevent future freezing, it is recommended to cover the valve with an insulation cover. By taking these steps, you can effectively protect and maintain the functionality of your backflow prevention valve.
