    How old is your house and what material are the original pipes made of?
    This will be a volume problem, pure and simple. Regards, Tom

    You got that right Tom, sounds like some wanted more volume at the new bathroom but connected to a small pipe, then big, then small again. Does not work like that, try feeding the new bathroom from the main, hopefully it is 3/4 or bigger. If it is only1/2" run 1/2" lines.

    Are you on a pump or city water? When the house was remodeled did they replace the water service line? Let me ask again, How old is your house,(the real age) and what material were the original pipes made of? Regards, Tom
