do I run the risk of damaging / distorting the pipe if I use a blow torch to clean off paint?
will using a blow torch also remove old solder that had run down a pipe?
I need to cut in to a pipe that has been painted and I've now discovered has a mass of old solder on it and unless I can clean it off in some way I am going to have to remove it and lift the floor boards to find a good bit of pipe to join it to.
wont distort copper pipes, using a blow torch is how the pipes would of been joined originally.
Yes this will also remove any solder, you shouldn't need to heat up the solder too much, just be careful not to melt the solder forming the water tight joints, if the pipes are full of water this will prevent this from happening as the water will keep the pipes and solder cool.
