PURPOSE:To precisely detect the presence of a water leak by hooking the hook piece of a jig on an injection nozzle, bringing the tip face of the peripheral wall on the cap side of a seal cover into contact with the inner wall of a bath room, and airtightly screwing and pressing a seal cover presser. CONSTITUTION:A hook piece 22 is hooked on the lateral hole 11b of the injection nozzle 11 of a circulation metal 10, a seal cover presser 24 is screwed while the rotation of a main body shaft 21 is prevented with a screw driver 30, and a seal cover 23 is pressed to a side wall 1a. The metal 10 is sealed on the discharge side by the cover 23. A booster pump 40 is connected at the middle of a circulation pipe 3, and pressure air is fed into the metal 10. The presence of a water leak from the metal 10 and a connection section around it can be detected based on the degree of the pressure reduction detected by a pressure gauge 50. |
