INSPECTION METHOD OF SIPHON DRAINAGE SYSTEM AND INSPECTION COMPONENT FOR SIPHON DRAINAGE SYSTEM
To enable inspection of generation of a siphon force in draining time in the vicinity of water section fittings in a siphon drainage system.SOLUTION: An inspection method of a siphon drainage system comprising a horizontal pipe 21 discharging drain from a kitchen sink 16 (a water section fitting) in a roughly horizontal direction, a vertical pipe 22 connected to a downstream end of the horizontal pipe 21 and arranged vertically downward, and a vent valve 24 (a ventilation part) provided upstream the horizontal pipe 21 and capable of in-taking atmospheric air into the pipe, includes: a first step S1 of attaching, to the vent valve 24, a bag body 40 (an inspection component) capable of detecting a negative pressure occurring in the pipe when a siphon force generates; a second step S2 of introducing drain into the horizontal pipe 21; and a third step S3 of confirming the presence/absence of the siphon force generation by the bag body 40.SELECTED DRAWING: Figure 2
【課題】サイホン排水システムにおいて、排水時にサイホン力が発生しているか否かを水廻り器具の近傍で検査できるようにする。【解決手段】サイホン排水システムの検査方法は、台所シンク１６（水廻り器具）からの排水を略水平方向に排出する横引き管２１と、横引き管２１の下流側端部に接続され、鉛直下方に配置された竪管２２と、横引き管２１の上流側に設けられ管内に外気を取入れ可能な通気弁２４（通気部）とを備えるサイホン排水システムの検査方法であって、通気弁２４に、サイホン力発生時に管内に生じる負圧を検出可能な袋体４０（検査用部品）を取り付ける第１工程Ｓ１と、横引き管２１に排水を流入させる第２工程Ｓ２と、袋体４０によりサイホン力発生の有無を確認する第３工程Ｓ３と、を有する。【選択図】図２
