WATER PIPING WASHING METHOD AND WATER PIPING WASHING TOOL USED THEREFOR
To provide a method for easily and effectively washing an inner surface of a bent trap part and a water piping part behind the bent trap part even if supply pressure of washing water to be supplied is as low as the supply pressure of tap water.SOLUTION: A washing tool is used which has a plurality of linear metal elastic bodies forming a strand form around a center axis of a flow channel of a pipe body of a washing water supply pipe, and a washing nozzle at a washing water outlet port thereof. The washing nozzle has a guide surface formed such that many washing water injection holes are opened and a front end side is a convex curved surface.SELECTED DRAWING: Figure 1
【課題】 供給する洗浄水の供給圧力が水道水程度の低水圧であっても、屈曲したトラップ部やその奥の水用配管部分の内面を簡単かつ効果的に洗浄できる方法を提供する。【解決手段】 洗浄水供給管の管本体の流路中心軸線周りにストランド形態をなす線状金属弾性体を複数設け、その洗浄水流出口に洗浄ノズルを設けた洗浄具を使用する。洗浄ノズルは、洗浄水の噴射孔を複数開口するとともに、前端側が凸湾曲面となるように形成されたガイド面を有する物を使用する。【選択図】 図１
