That 4” backflow device is installed 4-6” above the floor. A plumbing code is minimum 12” from the floor. Also, that FDC line definitely requires two check valves. An air compressor is placed on the floor , what is unacceptable.
Should they be 2 check valves ? One for each FDC and not just one. To prevent flow from one FDC to e other ?

Eric Corona jr that will depend on the type of hose valves. They might be using the flapping valves build in. But good observation
