my this place has become unfriendly lately

The OP comes here looking for answers and a fight breaks out, the
simple solution ignored.

do note replacing sections of galvanized is a big hassle, connecting
to old rusty galvanized must use die electric unions or fast rust out
will occur, and many have learned putting a wrench on old steel pipe
that looks fine can crush it easily.

all in all its way easier to replace a entire run with PEX, today
plumbers dont like that its way too easy to use.
