The corner valve in the toilet is broken. What about the wall?
Find a worker outside and repair it. You can't do it yourself.
With six corners to get in, and when there is time, then connected to the screwdriver, did not loose, a turn on the inside of the angle valve to get it, a minute.
My family has been two times, only a screwdriver with a chisel to knock out slowly. Find a worker outside and repair it. You can't do it yourself.
