PURPOSE:To enable to perform easy cleaning for the cleaning of drainage pipes of the kitchen sink and the bath room etc., by a method wherein high pressure water is splashed under control to any direction in the limited space. CONSTITUTION:When a bellows type flexible heated water supply pipe of a household gas boiler is used as a material of a pipe, one end of said pipe is improved to the size connectable to a household hose and a nozzle which is able to discharge high pressure water is attached at the other end. Especially when discharging hole is provided at the side of the nozzle, it is enabled to control the discharge to every direction in conjunction with the characteristic of the flexible pipe (curves 180 deg. at above 40cm). When cleaning the drainage pipe, it is made possible to perfectly cover the inner wall of said pipe by inserting the flexible pipe while rotating. Also at the cleaning of the bath boiler said flexible pipe is inserted to both open holes of the water supply pipe and the heated water supply pipe of the boiler from inside of the bath boiler, and the high pressure water is sprayed to every direction by repeating revolution and curving of said flexible pipe, and the cleaning can be carried out to the every nook and corner.
