Design by Peter Kirge -
A hose or plastic tube is attached to the inner nozzle on the Water Cap. This is then inserted into the water container. The cap is screwed on and the inner rubber washer ensures an air tight seal. The water container is half filled with water.
Then a longer piece of hose or plastic tube is attached to the outer nozzle and its other end installed in the flex tap. The flex tap works by creating a kink in the tube which controls or stops the water flow depending on how much the user flexes the handle.
A bicycle pump is connected to the schrader valve and the container pressurised with air.
