A backflow preventer () includes a body (). The body includes an inlet port () and an outlet port (). A central cylindrical bore () extends in the body and axially between the inlet port and the outlet port. A first check valve () and a second check valve () are removably mounted in the bore through an insertion opening (). A removable plug () is positionable in the insertion opening to hold the check valves within the bore. Some exemplary arrangements include a translucent body to facilitate visual observation of proper check valve operation and testing of the backflow preventer.
