I am close to finishing a bathroom remodel and it is time to put in the vanity. the water supply lines for the sink are too short and need to be lengthened to come through the floor of the vanity.
I am tempted to pull off the old water supply valves (4"?) and sweat in a new piece of copper (12") followed by a new supply valve.
I have not soldered copper before and completed this type of work but the videos that I see on you tube make it seem very doable.
That said, is there a lot more to this than meets the eye and is it difficult to get it done right so that a needle pin leak does not show up?
I can not afford for this to leak since the vanity would be installed over my work and followed by subsequent, somewhat permanent changes (PVC trap glued and connected to sink, etc)
What do you think? I have had a plumber over 2 times already to make sure the toilet was done correctly (difficult flange replacement).
