I'm remodeling my bathroom. Last night I took the cement board off the wall where the pipes run for the shower. One of the pipes that carries water to the shower was corroded. Upon further inspection, I noticed a small leak at a threaded joint (more or less where the hot water knob is). Can I simply take the joint apart, wrap teflon tape around it, and put it back together? Remember, when I get the bathroom rebuilt, this will be behind the tile shower, so I do not want to have to get back there again. How long should the teflon tape last?
Would you advise doing the cold water side too? I figure it is only a matter of time before that is leaking too. Might as well get it now, right?
