A backflow preventer (10, 128) includes a body (12, 130). The body includes an inlet port (14, 132) and an outlet port (16, 134). A central cylindrical bore (26, 144) extends in the body and axially between the inlet port and the outlet port. A first check valve (40, 152) and a second check valve (42, 156) are removably mounted in the bore through an insertion opening (38, 150). A removable plug (94, 95, 158) 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.
