Backflow Prevention


Watts backflow preventer valves are plumbing devices that stops the reverse flow of contaminated/polluted water, at service entrance or individual outlets, from entering your drinking water supply. The Watts Dual check valve back flow prevention is lead-free and has a copper poppet-type body, which minimizes water pressure, drops while allowing for continuous smooth water flow. Installation is made easy with its strait inline design that allows for either horizontal or vertical positioning.
