When does each tenancy require
a manual gas shut-off valve?
by Darrey Tilley, Senior Gas Inspector
With the adoption of AS/NZS 5601.1:2013
Gas installations on 31 March 2014, an
additional requirement was added to
consumer piping for a high-rise building.
It is now essential to have manual shut-off
valves in high-rise buildings.
Whereas in the 2004 version of AS 5601 a
manual shut-off valve was only required at the
gas entry point to each riser and at each lateral
branch, the new AS/NZS 5601.1:2013 requires
each tenancy to have a manual shut-off valve
fitted. This change of requirement, found in clause
5.7.4 (c) of AS/NZS 5601.1: 2013 Manual shut-off
valve in a riser and lateral, has caused concern
