Overview

Designed for installation on potable water lines to protect against both back-siphonage and back-pressure of polluted water into the potable water supply.  The Model 450 shall provide protection where a potential health hazard does not exist.

With a small 'foot-print', the Model 450 assembly allows for installation in cramped spaces and smaller enclosures.  As with all Wilkins backflow preventers, the 450 is known for its low head loss and easy maintenance resulting from Wilkins 'compound checks'.
