- About Us
All mechanical devices require routine maintenance. As a mechanical backflow prevention device protecting against contamination up to and including fluid category 4 fluids (contaminants which poses a significant health hazard) it is important to ensure, both those on site and the drinking water network, continue to be protected by regularly verifying the valve is functioning satisfactorily.
