I dont know what to do with a leaking pipe. Its a soldered joint, but
theres no way to drain it, so I cant think how to unsolder it. Both
feed and tap are at least 2' upwards of the bad joint. Drilling a tiny
hole in the Cu then solder patching it, am not convinced the solder
would be strong enough.

Also the access space is tight and theres a plastic waste pipe there
too, so I wont get free play with the blow j. Oh, and a plastic bath
too.

And of course the pipe looks somewhat corroded, so cutting the tee then
rejoining with compression is likely to fail. Such joy. Any hints
apprecated! Well, those relating to pipes.

Provided you can turn the water supply off, any pipe may be drained.

By the sound of it you'd be best to cut before the leak and replace
everything after it rather than mess about - or at least to where you can
get easier access.

You can get blankets to prevent heat damaging plastic pipes etc when you
use a blowlamp, or ceramic tiles do a pretty good job if you've got some
lying around.



If you can get a pipe cutter to it, push on fittings are the easiest to
use in a tight space, provide the outer surface is free from corrosion.

A wet soldering heat mat will protect any plastic when soldering.

Best of all though is to take the bull by the horns, and go even further
backwards from the leak to where you CAN make a good connection.

Even if it means using flexi plastic pipe to redo..this is often easier
to pull into tight spaces through walls etc.
