This report examines how the change of the negative pressure value and the positive pressure value of pipe pressure affects the drainage performance when the number of locations for installing air-admittance valves is increased. The main items to be examined are as follows: Understand the change of pipe pressure and air flow rate in relation to the change of the number of air admittance valves . Examine a workaround for the positive pressure which is important mainly for defining drainage performance and determine the threshold limit value of drainage performance. Propose and verify the piping model for prediction of drainage performance when multiple air-admittance valves are installed.
