Thanks folks for the replies.

This home failed functional flow tests at every bath and I recommended a replumb based on this and several other findings. It was a municipal supply - 115 psi at hose bib with NO water pressure regulator installed! I called this stuff out too. Certainly doesn't help the situation. Owners agreed to replumb - felt bad for them. They felt they were "wronged" by the original inspector who never mentioned any of this when the home was inspected 8 months earlier.

Oh, later in the inspection forgot to mention when i used the handle of my screwdriver to tap on the galvanized lines in a few "suspect" places, a pipe failed.

I hope his insurance is up to date...

This and other things gave my client over $5,000 credit on sale. Needless to say, they were ESTATIC!
