G. HOT WATER STORAGE CYLINDER CONNECTION
G1 . SYSTEM CONNECTION REQUIREMENTS
The plumbing connection to the mains pressure supply line MUST include the following:
• Isolating valve
• Non return valve
OR a duo isolating non-return valve in lieu of two individual valves
• Pressure limiting or pressure reduction valve
• Expansion control valve
• Drain cock (some areas only)
• Disconnecting union
• Line strainer ( if required to filter large particulates only )
• Correct pipe size and specifications. Note that only dezincification resistant (DR) brass fittings can be used
for potable water plumbing.
Note for some States and local council areas: It is a local requirement that an expansion control valve be fitted
on the cold water supply line between the non return valve and the water heater. Check with your local authori-
ties to see if this is required and fit according to local or State regulations.
