I just started using a 2nd floor shower that was built in the 60's. The supply is copper pipe and has not been used for all these years.
The problem is a constant roaring noise when either the cold or hot water is turned on.
I was hoping the sound would go away after using the shower for a few weeks but, that hasn't happened.
It almost seems like there is too much friction between the water flow and the inside of the copper pipe.
Has anyone run into this problem & solved it?
