Ok I am confused. Help me out here people! My bathroom tub and sink are fine. The shower is not. I can get water, but just a dribble. I ran it on hot for a LOOOONG time thinking it would melt any ice blockage, but it doesn't seem to. The pipe is warm in the basement part I can acess, but I can't reach any other part. Is it leaking on me somewhere?? Any clues??
