i have been doing a bit of diy plumbing... sinks, rads etc
i had a terrible time recently trying to fix a leaking 15mm water pipe. i
was using gas burner and solder/flux and just could not solder the 15mm
T-joint. the water was off at mains but i could not dry this pipe.. drips
is soldering a wet pipe a non-starter? if so i think i learned the hard way

If you thought about it for a bit, you would come to the obvious conclusion
that for at least 3 different reasons (all easily understood)
the above statement is CORRECT.
Although there are several ways to stop the water from leaking into the area
where you are trying to solder.
Water can only reach 100 degrees centigrade (212 Fahrenheit) before it turns to
steam. Solder melts at much higher temp than that. When something changes state
from liquid to vapor it absorbs a great amount of heat. If you have even a
bit of water near the joint, the temp will never rise much above 100 because all
heat will go into converting the water to steam.
and a new valve & solder it up fast. Then you have a shut off that works.
Well, I've had luck with the MAPP gas Turbo torch. Not all the time.
I seen some gaget that you melt later in the pipe. Anyone know of what
I seen ? Solder melts at 800 degrees ?
Hell, at Irrs they now have a tool that squeezes on fittings, the tool would
break your back if you used it all day. Costs like hell too.
They sell a jet sweat tool that does pretty well. I don't know about
you other guy, but if I have a leak problem, plain old white bread
stuffed into the pipe works fine.
You find frequently that city shutoff don't completely SHUT OFF. I
made a little gadget with a 1-1/4 fernco on one side that adapts to
3/8" tubing on the other side. In a pinch, I simply pull one of the
supply tubes and hook the fernco side onto my shop vac. It does a
great job combatting those water problems but creating suction and
keeping the water away from my work area. It's a work around. But it
