These systems must include protection to prevent possible backflow of irrigation water into the potable water supply.Federal law requires a proper backflow device to be installed on any watering system to prevent contamination of the supply; whether it be pump or city water. Check your local water authority for installation requirements & codes. In many rural areas; specific requirements for landscape irrigation systems may not be covered in local plumbing codes and/or enforcement may be limited. HOWEVER…limitation in local authority does not alter the basic requirement for protection of the potable water supply.Related Articles & VideosArticles How to Replace A Bonnet and Poppet Types of Backflow Preventers Atmospheric Vacuum Breaker (AVB) Pressure Vacuum Breaker (PVB) Double Check Valve Assembly (DCVA) How To Winterizing Your Sprinkler SystemVideos Choosing a Backflow Preventer Winterizing Your PVB Insulated Backflow BagsReplacement Parts Pressure Vacuum Breaker (PVB) PartsDimensions (in.)ORDERING NO.SIZEABCWT.(LB.)4A503021/2″4 1/23 3/47 1/43.24A504023/4″4 3/44 1/87 5/83.84A505021″5 3/84 5/88 3/85.24A506021 1/4″7 3/85 3/410 1/49.14A507021 1/2″7 1/25 7/810 3/812.54A508022″8 7/86 3/411 7/821.0
