A, backflow preventor which permits adjustment of the outflow direction is provided. A conduit (228) provides fluid com- munication between the two valves of the backflow preventor. The conduit (22 8) can be separated, e.g., by cutting along a groove (316), leaving annular flat regions (312, 314). The annular flats are configured to engage with a coupler to provide leak-free con- nection between the separated portions of the conduit. The separated portion s of the conduit can be rotated to adjust the outflow direction. Preferably, an infinite number of outflow directions are possible , all of which lie in a plane parallel to the inflow direc- tion. |
