Examples of Manifolds for Chemical Tubes. Your equipment can look different.
Close the line.
If the pump does not always close the line when it is off, use a shutoff valve to do this.
Do not let a vacuum occur.
Supply a vacuum breaker in the chemical line that is higher than the full level of the tank.
Flush the chemical tube with water.
If the liquid that stays in the tube between the pump and the machine can flow in the machine,
flush the tube with water after the pump stops.
Put the chemical tube fully below the inlet.
It is also necessary that there is no pressure in the chemical tube or tank when the system is off.
