EMERGENCY BACKFLOW PREVENTING SYSTEM
In an exemplary embodiment, an emergency backflow preventing system is disclosed that includes an inflatable bladder, an air supply line demountably coupled to the inflatable bladder, a valve demountably coupled to the air supply line, and an air source functionally coupled to the valve. The inflatable bladder includes a deflated state and an inflated state and is substantially void of air in the deflated state. The inflatable bladder is configured to be inserted within a sewage pipe when in the deflated state. The inflatable bladder is configured to contact a bore of the sewage pipe when in the inflated state and thereby wedge itself within the sewage pipe. The inflatable bladder comprises an elastic polymer. The valve comprises a Schrader valve and an air pressure gauge. A cable is positioned within the air supply line and is anchored within the valve and the inflatable bladder.
