My gas fitter is finding it difficult to source a "union" join to enable the gas line to be connected to the gas heater unit.We are in Mildura and having great difficulty sourcing the 6/8ml union join locally.
I recently had to get a 10mm gas pipe reduced to 6mm for a connection to the water heater (New gas Burner) The new connector was an olive compression type and the original was a flared type.
I was told by the gas fitter that compression fittings are no longer legal in Qld.
I had to have a small engineering firm make a flared connector to be silver soldered into the 'New' Compression fitting. It did the job at a cost of $25 including pressure testing.
It did the job and it all tested out OK.
Not sure if you have a similar problem or just unable to get the smaller fittings.
If it's the latter try an air conditioning fitter. A lot of the copper pipe they use is six and eight mm.
