Abstract
A liquid sanitizing agent is drawn into a capillary conduit section of defined volume, then separated from the supply thereof by opening an atmospheric back pressure vent at the lower end of the capillary section at substantially the same time said capillary section is filled. The sanitizing agent in the capillary section is then pumped as a liquid plug of defined volume into the sanitizing system of the warewasher.
