Water treatment foot valve and chemical storage container

The image depicts a blue plastic industrial jerry can used for chemical storage, paired with a white plastic foot valve or suction filter connected via a tube. This setup is typical in water treatment systems, swimming pool maintenance, or industrial cleaning, where precise chemical dosing is required. The foot valve prevents backflow and filters debris to protect the dosing pump. The blue tank is a standardized industrial vessel commonly manufactured by various plastic molding companies across Europe and North America. Due to the absence of legible branding markers or labels on the dirty surfaces, the specific manufacturer of the valve and the container cannot be definitively identified.
