Backflow Preventers

WATTS -

Reduced Pressure Zone Backflow Preventer
Reduced pressure zone backflow preventers by Watts are used to prevent the reverse flow of liquids caused by backsiphonage or back pressure in a plumbing system. They also eliminate the chances of entry of contaminants back into potable water supply lines. These Watts backflow preventers feature a compact, modular design for installation in tight spaces and their single-cover, top-entry facility allows easy accessibility for maintenance purposes. They come equipped with replaceable seats and seat discs, and do not require any special tools for servicing. Raptor Supplies offers a wide range of Watts reduced pressure backflow preventers in different connection types and body materials.
