After closing the ball valve, it is necessary to release all the pressure in the ball valve before disassembly, otherwise it is easy to cause danger. Many people do not pay attention to this point. After the valve is closed, it is immediately disassembled, and there is still a certain amount of pressure inside. This part of the pressure is not released, which is not conducive to personal safety. After the ball valve is disassembled and repaired, it needs to be installed according to the opposite direction of disassembly, and tightened and fixed, otherwise there will be water leakage. If you want the PVC ball valve to last longer, it is necessary to reduce the number of switches as much as possible. When a water leak occurs, it needs to be repaired in time to return to normal use as soon as possible.
