However, it is offered to provide background information.ASSE Product Standards are developed in the interest of consumer safety.The American Society of Sanitary Engineering is dedicated to the preservation of public health and safety through its guiding principle, “Prevention Rather Than Cure.”ASSE’s Product Standards Program systematically evaluates new technologies through formal requests and addresses the development and promulgation of performance standards designed to safeguard public health and safety.Standards for the performance of plumbing system components are considered by the American Society of Sanitary Engineering to be of great value in the development of improved plumbing systems for increased protection of public health and safety.To accomplish this, ASSE, through its Product Standards Committee, encourages manufacturers to develop performance standards and testing procedures for their products. These standards have the consensus of manufacturers and others who have pertinent interests in plumbing systems and are acceptable to this Society.ASSE recognized that the common garden or utility hose, when connected to a potable water supply by means of hose threaded outlet, constitutes a potential non-potable cross-connection and that a performance standard for preventive means, the vacuum breaker wall hydrant, was warranted. ASSE Standard #1019, Wall Hydrants Vacuum Breakers Frost Proof Automatic Draining Types, was developed and issued to fulfill this requirement.Plumbing codes now stipulate that hose connections shall be protected by approved vacuum breakers that conform to the performance requirements of ASSE Standard #1011. Accordingly, hose bibbs, sill cocks, lawn faucets, frost-free wall hydrants and the like must be so equipped.Frost resistant wall hydrants equipped with hose connection vacuum breakers pose a restriction to the post closure drainage, which is essential for frost prevention. Such vacuum breakers must be manually triggered to permit drainage, thereby, in effect, negating the frost proof feature of these hydrants which relies on automatic drainage. Thus, it becomes readily apparent to manufacturers of frost proof hydrants that resolution of this matter would involve the development of hydrants that incorporate vacuum breakers and retain the automatic draining provisions essential to frost resistant design.iv Wall Hydrant with Backflow Protection and Freeze ResistanceASSE 1019-2011During the 1988 revision of ASSE Standard #1019, the ASSE recognized the need to consider two types of wall hydrants for backflow protection. Specifically, test criteria was developed for frost proof and automatic draining type wall hydrants. In 1995, a request was made to revise the standard to include a third type of wall hydrant for backflow protection, which holds pressure versus relieving pressure.The life cycle tests contained in this product performance standard represent the average expected life of the product.Although many of the material specifications are detailed within Section IV of this standard, it is the responsibility of the manufacturer to comply with the requirements of the Safe Drinking Water Act, United States Public Law 93-523.The 1019 Working Group, which developed this standard revision, was set up within the frame-work of the Product Standards Committee of the American Society of Sanitary Engineering. Recognition is made of the time volunteered by members of this working group and of the support of the manufacturers who participated in meetings for this standard.The standard does not imply ASSE’s endorsement of a product which conforms to these requirements.Compliance with this standard does not imply acceptance by any code body.Plumbing codes mandate how and where these devices are installed. However, this standard was promulgated using a specific set of installation requirements and conditions for the purpose of providing reasonable performance requirements and compliance testing.It is recommended that these devices be installed consistent with local codes by qualified and trained professionals.This standard was promulgated in accordance with procedures developed by the American National Standards Institute (ANSI).This edition was approved by the ASSE Board of Directors on July 7, 2011 as an ASSE standard.--`````,,,,,`,,``,``,,,,`,``-`-`,,`,,`,`,,`---Wall Hydrant with Backflow Protection and Freeze Resistance vASSE 1019-2011Joseph FugeloProduct Standards Committee ChairmanLabov Co.

The backflow protection shall include a minimum of two (2) mechanisms: an air inlet for preventing backsiphonage and a check valve for preventing backpressure backflow. These devices are terminal fittings that supply potable water to hose connections without danger of freezing.These devices shall be used on systems where the only source of low head backpressure comes from an elevated hose equal to or less than 10.0 feet (3.0 meters) in height. The outlet of this device shall not be subjected to more than twelve (12) hours of continuous water pressure.The devices shall be classified as follows:(a) Type A devices protect against backsiphonage and backpressure.
