A backflow preventer assembly includes a housing having a first end and a second end, a first mounting assembly configured to removably secure a first check valve at a region of first end of the housing, and a second mounting assembly configured to removably secure a second check valve at a region of the second end of the housing. The housing includes a wall having an inner surface defining a through bore extending between the first and second ends. Each mounting assembly has a wall with an inner surface defining a through bore in fluid communication with the housing through bore. A first coupling secures the first mounting assembly to the housing, and a second coupling secures the second mounting assembly to the housing.
