A through hole 4a is formed in. If concrete, mortar, or the like is attached to the end surface of the elbow 2, a tool is inserted through the through hole 4a and removed. Then, a "sprinkle socket" or the like is attached to the elbow 2, and a water pipe 1 or a gas pipe and a faucet or the like attached to the side of the room 3 are connected by piping. As a method of forming the through hole 4a, a plumbing plug, a so-called kiss plug 5, is connected to the elbow 2 before the wall member 4 is erected, and the tip 5a thereof is projected toward the room 3 side. If the wall material 4 is erected in this state and the kiss plug 5 is removed after the concrete, mortar, etc. of the wall material 4 has hardened, the kiss plug 5
After that, the through hole 4a is formed.

要するという問題がある。However, in the conventional plumbing plug, so-called kiss plug 5, concrete, mortar, etc. contract when the wall material 4 hardens, so that the outer peripheral portion of the kiss plug 5 becomes the wall material 4. Due to the strong pressure, the so-called kiss plug 5 for plumbing cannot be easily removed. Therefore, since concrete, mortar, etc. around the kiss plug 5 are cracked to form a space around the kiss plug 5 for removal, there is a problem that it takes a lot of time for the removal work.

However, since the spacer is firmly attached to the wall material or the floor material, the plug main body is separated from the spacer and pulled out while the spacer is attached to the wall material or the floor material. After that, a part of the spacer is peeled off from the wall material or the floor material while the spacer is deformed inward by pliers, pliers or the like. By repeating this in sequence, the spacer is peeled off from the wall material, so that the entire spacer is removed from the wall material, and then the through hole is formed.

When the driven force 14 of the plug body 11 is rotated by a spanner when the tightening force is strong, the plug body 11 is separated from the elbow 2 as described above. However, the spacer 12
Is firmly attached to the wall member 4, the plug body 11 is separated and removed from the spacer 12 with the spacer 12 attached to the wall member 4 (see FIG. 3). After that, a part of the spacer 12 is grasped by pliers or pliers 17 and deformed to be peeled off from the wall member 4 (see FIG. 4). By repeating this in sequence, the entire circumference of the spacer 12 is peeled off from the wall material 4, the spacer 12 is finally removed from the wall material, and then the through hole 20 is formed (see FIG. 2).

As shown in FIG. 5, the pour-in socket 21 has a through hole 21a that penetrates between both end faces to allow water or gas to flow therethrough. A screw portion 21b that is screwed into the screw hole 2a of the elbow 2 is projected on one end surface, and a screw hole 21c into which the screw portion 22a of the faucet 22 is screwed is formed on the other end surface. A hexagonal hole 21d that engages with a hexagonal wrench is formed at the end of the flow hole 21a. This sprinkled socket 21 is held by a hexagonal wrench engaged with the hexagonal hole 21d and inserted through the through hole 20,
It is attached to the elbow 2 by screwing the screw portion 21b into the screw hole 2a of the elbow 2. In this attached state, the other end surface is substantially flush with the wall member 4. g. Then, the threaded portion 22a of the faucet 22 is screwed into the screw hole 21c of the sprinkle socket 21 to attach the faucet 22 to the elbow 2.
