AS 4796:2016 Water supply—Metal-bodied and plastic- bodied ball valves for property service connection
1.3.2 Component
A part or a subassembly of parts that contributes to the construction of a total assembly by choice or design and which may offer variations of fitment for the application to the major element of the product, whether produced by the same manufacturer or not.
NOTE: The component is deemed to be a vital part of the total assembly and should not inhibit the product from complying with this Standard and any other relevant Australian Standard, when submitted for type testing.
1.3.3 Distortion
Dimensional change that is obvious to the eye without resorting to dimensional checking or that which physically inhibits the operation of the valve.
1.3.4 Right angle meter assembly ball valve
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.
1.3.5 Service connection ball valve
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.
1.3.6 Service connection termination ball valve
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.
