OGDEN CITY PUBLIC UTILITIES W A T E R Q U A L I T Y A cross connection is simply a connection between the drinking water system and anything that has the potential to degrade the water in any manner. Any time pressure in the public drinking water drops to 0 psi or below, there is a possibility that contaminants may be drawn or forced into the drinking water system. This could be caused by a break in the water distribution line, by opening a fire hydrant, installation of high pressure equip- ment , or a number of other common occurrences. Backflow is simply the reversal of the normal flow of drinking water in a system. The requirement to prevent backflow is stated in the International Plumbing code (IPC) adopted by the State of Utah, Section 608.3 Plumbing Fixtures. The supply lines and fittings for every plumbing fixture shall be installed so as to prevent backflow. The drinking water system must also be protected from connection to chemical dispensing systems. There are two options available: • The dispensing unit has been tested and la- beled with an ASSE 1055 sticker indicating the dispensing unit has been tested or shall be equipped with an air gap fitting.
