A check valve is a type of valve that allows fluid (usually water) to flow in one direction while preventing backflow in the opposite direction.  This part is based within the isolation valve section. The isolation valve is usually situated underneath your appliance and allows the user to regulate the flow of water and gas in to the central heating system. These also allow you to stop the flow completely in case of a leak or emergency.
