Diverters for Plumbing Faucets with i Hose Spray, Anit-Siphon Type, Residential Applications ii Diverers for Plumbing Faucets with A.S.S.E. - 1025 Hose Spray, Anit-Siphon Type, -Residential Applications Issued 7976 Foreword It is a principal objective of the American Society of Sanitary Engineering to work with manufacturers of plumbing oriented products in the development of product perance standards which are directed to health and safety of the public in general. When assistance was requested for a standard for Diverters for Faucets, the A.S.S.E. Standards Committee responded promptly to implement this project. The cooperation of representatives of several different segments of the plumbing industry working together, contributed broad expertise and experience to the project. Represented were manufacturers, health and inspection officials, master plumbers and others with knowledge of the problems related to the products and intended purposes. The text as recited herein was studiously developed around factors pertinent to the health and safety of the users as they were captured from the cooperating subcommittee personnel. This standard has been accepted and approved by the A.S.S.E. Stan- dards Committee which action has been concurred in by the Board of Directors of the Society. The standard has now been issued as an official A.S.S.E. Standard under title number 1025, date of February, 1976.

Back Pressure A pressure in the supplied system which, for some cause, becomes greater than the supply pressure. in this text, it is pressure above atmospheric. Back Pressure Backflow A reversal of the normal and intended direction of flow caused by back pressure. Backsiphonage The application of the siphon principle in a water supply line which produces a flow of water in the direction opposite that normally produced by the force of gravity. Backsiphonage Backflow Generally referred to as only backsiphonage A condition in a piping system, or portion of a system, deployed in the of a simple siphon in which the supply pressure falls to less than atmospheric and the supplied system pressure becomes atmospheric, the activating pressure. Cross-Connection, non-potable Any connection to a potable water supply system through which potable water is supplied to a service outlet through which contaminants can enter the potable water supply lines by back pressure or backsiphonage backflow. Detergent Brush A hose and brush assembly with detergent supply for cleaning utensils and other services for attachment to a faucet with a built-in diverter. Interconnection A cross connection between two separate systems. Le.
