How does the attachment prevent contamination?

The attachment prevents contaminants from entering the water supply by sealing off the opening. When the cistern is filled the attachment opens and allows the water to enter safely.

How does it function?

One end of the coupling connects to the hose used to deliver water while the other connects to the base of the cistern opening. Because of this our product is suited towards those who deliver their own water and for communities where delivery is regulated by one service.

What type of cistern does the attachment fit?

Our product was designed with underground and outdoor cement and plastic cisterns  in mind. However it is possible it could fit other kinds; contact us for inquires. Note that your cistern must have at least a 6 inch diameter.
