Both technicians are correct. Technician A is correct in that a magnet should never be used to remove check balls as it can magnetize them and cause them to stick to the body of the valve, causing malfunctions. Technician B is correct in that it is important to document the location of the check balls during disassembly to ensure they are reinstalled correctly during reassembly. Taking a photograph or drawing a diagram of the valve body can be helpful in reducing the risk of misplaced or incorrectly installed check balls.
