Another badley installed retic system
As you can see from the photo below the person who installed this system has run the station lines directly on top of the none return valve and master valve making this repair at lot harder to complete.
Waterwise standards are to run all valves in a line and leave 300mm from a valve before putting in any junction to aid in any repairs or maintenance needed in the future like in the picture below that was installed by TLC Reticulation on a pre made manifold
