I got a new hot water tank last summer. Since then, the hot/cold mix of water in my shower is off balance. In order to get hot water in the shower (and in the shower only) the hot needs to be on full and the cold needs to be barely turned on at all. This condition does not exist if we use the tub only, and it doesn't exist on any of the other faucets in the house, only this shower.

Anyone have any suggestions?

Thanks.
