I am ready and about to buy materials for the repiping from galvanized
1/2" to copper ?", but what size to use? I would like to go with 1/2"
type K but that takes up more inside diameter then M and L. Should I
go with 5/8" K, 3/4" K or just not be worried about the inside
diameter because it is a very small difference? Then again the
galvanized pipe probably has only an 1/8" openning anyway from all the
years of crap in it.
