Watts 0065372 3/4" Backflow Preventer 919QT

Watts' 0065372 919Qt is a 3/4-inch lead-free reduced pressure zone backflow preventer. This device protects your potable water supply from contamination caused by back siphoning or backpressure. Back siphonage occurs when contaminated water is forced back into the clean water system due to a pressure difference. Backpressure occurs when pressure from another source pushes contaminated water into the clean water system. The 919Qt is widely used in various HVAC applications, including boilers, cooling towers, and irrigation systems. The Watts 0065372 919Qt is designed to be compact and modular, making it simple to install and maintain. In addition, it has separate access covers for in-line repairs and requires no special tools to operate.
