What About Sodium Hypochlorite (NaOCl)? Flow Control

The trapped sodium hypochlorite starts to decompose and crystals begin to form. The crystalline salts adhere to the surfaces of the ball and seals - causing a freezing of the valve and making it inoperable. When the valve is operated, the torque required to do so may be greater than the strength of the valve stem - causing it to break.
