Abstract
Systems and methods for controlling liquid flow to the liquid supply of a beverage forming apparatus. The liquid supply may include two valves positioned in series for controlling a flow of a liquid into the liquid supply. Pressures upstream, between and/or downstream of the valves may be detected and used to determine if one or both of the valves leak when closed.
