If it is leaking when you use the shower, not shutting off completely, it will need to be replaced. If it is leaking at the wall, take it off and reseal the thread on the pipe with either pipe dope or Teflon tape and reinstall.
Take some screws, screwdrivers, nuts and spanners firstly open the leaking area fix it with some well branded glue , fill it with cement and tile it. Screw it and fix nuts with spanner.Now it is fixed.

When you discover your water heater is leaking, if you can't afford to fix it for a while, then you should put something down to catch the water. If you have money you should call a repair company from the phone book.

You have to say WHERE it is leaking from for someone to answer it.
If it is coming from the tub spout then the gasket is moving around or esle it is shot. The easiest way to fix this is to get a new tub spout. It will more than likely take more time to attempt to change the gasket on the spout then to install a new one.
Your tub spout isn't fully diverting the water to the shower head and a very small amount is leaking through. The smaller the hole the water has to exit, the greater the pressure. Replace the tub spout, usually costs less than 20 dollars.
I usually fit spout 6-8 inches above tub.
You probably have a bad heater core. The heater core is installed in a plastic casing and the spout is there in case it starts leaking. This keeps it from leaking into the floor of the car.
If the tub has a shower as well, the pipe from the faucet to the shower head could be leaking. You might also check the tube that comes OUT and fills the tub. It could be leaking back at the valve when you turn on the water.
The spout is not leaking, the O ring on one of the valves are. Turn your water supply off and take the valves off and replace the O rings
NO - you would have to change valve out
For the ceiling to be damaged there is a leak! As to who's fault it is that is the question. It is determined by who is responsible in your apartment for the upkeep of what is leaking. Some of the causes could be a leaking tile wall or tub surround, water leaking where the valve or spout protrudes through the wall, a drain leaking, the shower valve or piping leaking, water spilling over the edge of the tub on the floor or even a roof or window leaking. I would recommend hiring a plumber to investigate and repair any leak that is occurring as most of the time it would be your responsibility for repair. A leak is not going to get any better on its own and water damage costs can be significant.
