I just completed the replacement of the hot and cold water stems form my bathtub faucets. The hot water was leaking so I went ahead and replaced both. They were probably original to the house circa late 50's. After finally getting them loose I inserted new correct replacements. The problem now is that when I run the hot water I only get cold water. I let it run for several minutes but still had no hot water coming out. There is hot water everywhere else in the house, even the sink near the tub. Has any else ever heard of this or encountered this problem.
