I had my main water line replaced at the same time I had my sewer line replaced. The water pressure in the house is the same with the exception of the bathroom in the back of the house. It is now a trickle, doesn't matter if I turn the hot or cold water on separately or togethe, it is a trickle turned on all the way. Before it was a stronger flow but not one that I would call normal. The shower in the same bathroom seems to be working the same as before. Help!
