Water leak Whenever it was rainy, the water leaked from the ceiling in my office. It was very dangerous to work indoors. So one of my staffs opened the ceiling, looked carefully. A box was on the metal bridge. Maybe someone put it to prevent from falling the water long times ago. We needed to bigger box to receive the water. The points of water leakage was two. Two box was put end to end to make one long box. He drilled each hole of two boxes. He inserted a tube into the hole and used glue gun at the crack.
