In this study, with the purpose to improve the ability for drainage, the possibility of the drainage performance forecast was examined by proposing the network model to request the jurisdiction pressure that became the judgment index of the drain ability when this vent valve was set up in the horizon-tal fixture branch in two branches. Moreover, it is all-out to generate an excessive, positive pressure by excessive ventilation because the number of installation places increases. Therefore, the ventilation resistance in the housedrain increased when the ventilation flowing quantity increased, and the prediction method of the increasing positive pressure value was examined in the low layer floor when the horizontal bend was set up in housedrain of the drainage stack system.
