]I will appreciate any help you can provide me. Every time I turn on water in the bathtub thewater start to run from the showerhead which is located in different bathroom. The bathtub is located in the bathroom on 2nd floor andshower located downstairs on the first floor. I changed the valve but it did not help. Do you think it may happen because we removed water heater which we areplanning to replace later on. I did notlive in this house before so I do not know if this problem was happening whenwater heater was in place.
