The problem I have is that the pipe is an old lead one and it is 21mm
in diameter it also has thick walls of about 3mm. I tried to put a
22mm end stop on it which held for a while with some PTFE tape but the
pressure build up caused it to blow off the end quite spectacularly.
At the moment I have a great water feature but I need some help
stopping it!

Can anyone identify this kind of pipe and where I can get an end stop
for it from?

Quick fix...go to the plumbers merchant, tell them the size of the pipe,
and ask for a Johnson coupling. This fits a range of sizes (within
limits) and you can put a bit of end-stopped 22mm copper in the other
end.



Even quicker fix ... flatten end of lead pipe with hammer, bend it over and
flatten again .... used to be fairly common way of temp stopping off lead
pipes.
When I learnt my lead jointing ... an accepted permanent fix was to solder
an old penny across the end of the pipe , piece of moleskin, some tallow,
blowlamp and plumbers solder.
.... but namby pamby plumbers of today probably have a quick fit plastic
thingy to do the job at 20 times the price !

Well some 20 years ago when I was desperate to cap off a 22 mm tee
junction I found that a pound coin was a very good fit and a few weeks
ago I had to alter that pipe work and removed the coin and cleaned it up
and its still usable!...


If I were wanting to do it now .. I'd bell the end of the pipe to flare it
open a bit, tap in a piece of 22mm copper do a quick neat copper to lead
joint .. the flare will help form a cup for the solder, wipe it smooth.
Then stop off or put a tap or whatever on the copper end.
