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
Great Point Bro!!
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.
