As a tester for these devices we feel the inspection schedule is at a minimum now, these devices are very important to the life safety for the citizens in any given area.  This seems a simple task that has no negative consequences, but anyone who would look into what has and could happen if back flow did occur on a domestic water supply system. Please when considering this change use your time to understand these safety devise’s,  what they protect the citizen from, consider the lives that it could/will affect should the unimaginable happen.
