I hope someone can help me here. We have no hot water (only a trickle) coming from our bathtub. The cold works fine and the other faucets work okay. Water pressure has always been an issue in the bldg (40 years old), but not having any water. I talked to my neighbor and she said she has the exact same problem but our units do not face each other in any way. She said she was told the pipes in the bldg need replacing and it will never happen because it costs too much. Is there anything I can do? I live on the 4th floor of a 4 story bldg. There are 36 units and from what I've seen of the hot water heater, it looks too small, like one that would be in someone's home.
