In a word no!
Having said that my brother had a flat in central London where the pipes
were brazed - so no Tee joint, just a hole cut in the main run and the
branch brazed in. The joins in runs were pipe ends that had been expanded
and brazed. It was sufficiently unusual to provoke comment at the time
I've used 'Colphos' which I think is the braze you are referring to on
cooling pipes on my induction furnace and it was a very nice process
requiring no flux, but that was a rather special application where the pipes
also carried enormous currents.
Oh fuck. Rod is here now.
For anyone interested in antipodean plumbing:

2.6.1 Silver brazing alloy
126.96.36.199 Copper and copper alloys
Silver brazing alloys for capillary jointing of copper and copper alloy
pipes and fittings shall comply with AS 1167.1 and shall contain a minimum
of 1.8% silver and shall a maximum of 0.05% cadmium.
188.8.131.52 Stainless steel pipes
Silver brazing alloys for capillary jointing of stainless steel pipes and
fittings shall comply with AS 1167.1 and shall contain a minimum of 38%

2.6.2 Soft solders
The following limitations shall apply to the use of soft solder:
Soft solder shall not contain more than 0.1% lead by weight.
Soft solder shall only be used for jointing copper or copper alloy pipes to
capillary fittings of the long engagement type complying with AS 3688.
Soft solder shall not be used with coiled annealed pipes.
NOTE: In certain areas, soft-soldered joints may not be suitable due to the
chemical composition of the water and, hence, their use may not be
And, no I'm not a real plumber even though I don't wear a tie.
At last a voice in the wilderness, I am not mad Australia does use the
silver solder that I have been talking about and in some cases it is
compulsory contrary to one lot of advice that nowhere in the world does
You are right in your last remark.
There is a whole wadge of legislation in Oz to prevent DIY in just about
It is the ultimate nanny society.
Lead based solders in the UK are not allowed for potable water but are still
widely used for central heating and could be used for hot water.
I think electronics also has to be lead free also now.
Probably lead based solder will disappear altogether in the near future.
I think the replacement is mostly zinc.
Agreed. And that is where our stupid Part P building reg came from.
Not where avionics is concerned. Lead-free solder is totally banned for
anything important on a civil aeroplane. There are plenty of photos of
how lead-free joints fail on the web. There is one taken by cutting open
a transister can showing the 'whiskers' that seem to develop.
And anyway, I thought the refridgeration industry always brazes copper
pipework, and the pipe ends are usually flared on site using a special
tool whose name I forget.
Domestic copper piping has always used preformed sockets that are (were)
more suitable to low(er) temperature lead-based solder that uses
capillary action to fill the joint.
everything is different in Oz. I believe soldering electrical mains
cable is the preferred method, while we use junction boxes or crimps.
