A below-ground or above-ground valve, having a lockable operating mechanism and for location adjacent to the property water meter. This valve may be installed with the copper riser at the time of the reticulation pipeline installation, laid over at 90° and buried instead of the termination ball valve. When buried, this valve shall be installed in the same manner as the termination ball valve complete with the open-threaded end capped or plugged. This valve may also be installed by the plumber at the time of property connection.See Figure 1.3.
A below-ground valve for insertion into the water reticulation pipeline tapping fixture to deliver water to the property service pipe, and which is shut only for maintenance, failure or disconnection of the downstream installation. See Figure 1.1.A below-ground valve located at the property boundary for the plumber to connect the property riser at the meter assembly. The valve is initially installed, charged, tested and left for the plumber in the closed position with any open threaded ends protected with a plastic cap or plug. See Figure 1.2.
The long-term performance of pipeline systems is critical to the operating efficiency of water agencies in terms of operating licences and customer contracts. The long-term performance of plumbing systems is similarly critical to the durability of building infrastructure, protection of public health and safety and protection of the environment.Product conformance testing and certification shall be carried out by a body which is accredited by signatories to the International Laboratory Accreditation Cooperation (ILAC) through their Mutual Recognition Agreement (MRA) in the field and class of testing on behalf of the manufacturer for the purpose of establishing compliance with this Standard.
The frequency of the sampling and testing plan, as detailed in Paragraph A4, shall be used by the certifying body for product compliance auditing. However, where the manufacturer can demonstrate adequate process control to the certifying body, the frequency of sampling and testing nominated in the manufacturer’s quality plan and/or documented procedures shall take precedence for the purpose of product certification.AS 4796 pdf free download.
