This is an embodiment in the case where the water leakage discharge member 7 is connected to the plug elbow 2, and one end of the tubular water leakage discharge member 7 has one end as shown in FIG.
A female screw part 15 screwed into the male screw part 11 provided on the faucet connection side and a water guide part 14 having a larger diameter than the female screw part 15 are formed,
The other end of the water guide 14 faces the wall surface 3a.

As shown in FIG. 3, a groove 12 for tooling is formed in the other end surface of the water guide portion 14 and a circumferential groove 16 forming a step portion 31 for dropping is provided on the outer peripheral surface thereof. .

The water leakage discharge member 7 is screwed into the faucet elbow 2 in advance at the time of piping construction, and after finishing the wall 3, a wall hole 9 is opened, and a plate-shaped jig or the like is passed through the wall hole from the wall front side. By turning the water leaking and discharging member 7 into the groove 12 for tool hooking, it is possible to adjust the alignment with the wall surface 3a. Conversely, after the wall 3 is constructed, the water leakage discharge member 7 can be screwed into the faucet elbow 2 through the wall hole 9 from the front side of the wall and attached.

Then, the water leakage discharging member 7 is slightly protruded from the wall surface 3a, the washer 6 shown in FIG. 4 is fitted to the water leakage discharging member 7, and the dropping step 31 of the water leakage discharging member 7 is slightly protruded from the washer 6. .

The washer 6 is provided with a cutout 8 for discharging water leakage at the peripheral edge thereof. The cutout 8 is attached to the wall 3 with an adhesive so that the cutout 8 for discharging water leakage is positioned below. It is fixed to the wall 3 with small screws or the like, or it is pressed down and fixed with the dropping step 31. It should be noted that a vertical groove or a slit may be provided instead of the cutout 8 for discharging water leakage.

Next, the faucet 5 previously equipped with the feed seat 4 is screw-connected to the faucet elbow 2, and the peripheral edge of the feed seat 4 is pressed against the peripheral edge of the washer 6 to fix the faucet 5 to the wall 3.

If water is leaked from the faucet 5 and the faucet elbow 2 due to insufficient screw connection, the water leaks into the water guide 14 of the water leakage discharge member 7 and passes through the water guide 14 to the front side of the wall. Is discharged.

At this time, since the water guide portion 14 is larger than the diameter of the female screw portion 15, the water leak does not flow out of the water faucet elbow 2 through the threaded portion of the water faucet elbow 2 and the water leakage discharge member 7. The water is guided to the front side of the wall and drops as water droplets by the circumferential groove 16 at the tip of the water leakage discharge member 7 and falls vertically downward inside the feed seat 4. Therefore, the water does not flow back to the back of the wall so that the water leaks along the outer shape of the water leakage discharge member 7 and spreads.

The water leaks out through the notch 8 of the washer 6 to the wall surface 3a.

FIG. 5 shows a second embodiment in which the wall 3 is thick, the distance from the faucet elbow 2 to the wall surface 3a is large, and the faucet 5 cannot be directly connected to the faucet elbow 2. This is an example in which the faucet 5 is connected to the faucet elbow 2 through the intermediary of the water.

The leakage discharge member 7b faces the wall surface side. In this case, the water leaks to the wall surface 3a from the water leaking groove 8a of the washer 6.

FIG. 7 shows an embodiment in which the water leakage discharge member 7c is made of an elastic member such as polyethylene and the water leakage discharge member 7c contacts the faucet elbow 2.
c is held between the end face of the faucet elbow 2 and the inner end face of the feed seat 4 of the faucet 5 in a pressed and compressed state, and water leakage is discharged from the feed seat threaded portion 19. Note that the water leakage discharge member 7
The contact portion 32 between c and the faucet elbow 2 may be bonded with a double-sided tape or the like.

FIG. 8 shows a method in which the water leakage discharge member 7e is screwed to the inner screw 22 of the faucet elbow 2 and desired on the wall surface. Further, in this case, the water leakage discharge tube 7e is connected to the feed seat 4 of the faucet 5.
And the water leakage is directly discharged from the end face of the water leakage discharge member 7e.
e is provided in the threaded portion of the feed seat.

FIG. 9 shows that the water leakage discharge member 7f is connected to the faucet elbow 2.
This is an example in which, instead of being attached to the tip, a projection shape 24 is provided at the lower part of the outer periphery of the faucet connection side tip of the faucet elbow 2 itself or at the entire periphery of the tip. Then, the storage portion 13 of the water leakage discharge member 7f is located at the water leakage falling position or the outer periphery of this position, and the water leakage is guided to the wall surface side and discharged to the wall surface 3a. In this example, a water leakage discharge member 7f is attached to the wall hole 9.

FIGS. 10 to 12 show a modified example of the water leakage discharge member. The embodiment shown in FIG. 10 shows a case where the water leakage discharge member has a gutter shape.

The embodiment shown in FIG. 11 is a bellows type water leakage discharge member 7i, in which the end 25 abuts on the end face of the faucet elbow, and the end 26 abuts on the inner end face of the feed seat of the faucet in the opposite direction. The position error of the construction is absorbed by the bellows 27. When the end portion 25 contacts the faucet elbow, it is assumed that the end portion 25 has water tightness enough to allow water leakage to flow out to the wall surface side.

The embodiment shown in FIG. 12 has two cylinders 7k, 7k.
m is a leakage-exhaust member 7j having a watertightness such that the leakage does not flow out from the insertion portion 28. Even when the wall thickness is largely changed, the two cylinders 7k, 7k
m can be easily handled by putting them in and out of each other. Further, as shown in FIG. 13, the projection 29 of the water leakage discharge member 7j is elastically attached to the groove 30 at the tip of the faucet elbow 2 so that the cylinder does not easily come off from the tip of the faucet elbow.
