The rise and fall action operates a lever, which opens and closes the valve (WHO 2006).<br /> # A float valve, commonly referred to as a float control valve, is an automatic valve used to control the water level in a water storage cistern or tank (Plumbing Working Group 2008).<br /> <br /> ==Explanation==<br /> A float valve, commonly referred to as a float control valve, is a simple form of control valve<br /> which regulates the water level in a storage container. The valve is activated by the water<br /> level. It has a lever arm with a ball float attached at one end. The arm and attached float<br /> supply the valve with mechanical force, enough to close the water valve attached to the<br /> opposite end. The valve opens as the water level is lowered below a pre set level (Plumbing<br /> Working Group 2008).<br /> <br /> ==Example==<br /> A float valve, commonly referred to as a float control valve, is found in cisterns, and water<br /> tanks. The float valve must ensure there is an appropriate air gap between the valve outlet<br /> and the highest overflow level of the water storage container to prevent any back flow from<br /> the tank storage into the drinking water supply (Plumbing Working Group 2008).<br /> <br /> ==References==<br /> * WHO (2006) [http://www.who.int/water_sanitation_health/publications/plumbinghealthasp/en/index.html Health aspects of plumbing]<br /> <br /> ==Links==<br /> * [http://apps.who.int/thelexicon/ WHO — The Health and Environment Lexicon]<br /> <br /> [[Category:EN]]</div>
