The first work for partially cutting and removing the pipe pipe at the place where the pressure reducing valve is to be inserted and the second work for inserting and connecting the pressure reducing valve to the pipe removing section are required. The work becomes complicated. Conversely, when the pressure reducing valve is removed after the piping operation is completed, the first operation of removing the pressure reducing valve from the piping and the second operation of reconnecting the piping pipe in place of the pressure reducing valve are performed. Required, and again,
The above two operations are required, and the work of redoing the piping becomes complicated.

配管方法。1. A method of branching a water supply circuit from a main pipe for water supply extending in a vertical direction to households of each level, wherein a pressure reducing valve is inserted near an upstream end of the water supply circuit to a level with high water pressure. In the water supply piping method, a main body case (4) through which a water passage from an inlet side pipe connection to an outlet side pipe connection penetrates, and a communication branched from the water passage and connected to an outer surface of the main body case (4). A closure lid (8) having a second coupled part that closes the opening on the outer surface side of the hole (45) and is detachably coupled to a coupling part formed in the main body case (4). Prepare pipe fittings to be provided, complete the pipe work once in the state where the pipe fittings are inserted near the upstream end of the water supply circuit of each household of the hierarchy where it is difficult to determine the necessity of the pressure reducing valve, the pressure reducing valve is If it is found necessary after the completion of the piping work, the second connection First the closing lid vacuum valve mechanism unit (5) constituting the pressure reducing valve with and the main body case provided with the coupling portion (4) having a part of the same structure
(8) A water supply piping method for an apartment house connected to the communication hole (45) instead of (8).

給水配管方法。2. A method of branching and supplying a water supply circuit from a main pipe for water supply extending in a vertical direction to households of each level, wherein a pressure reducing valve is inserted near an upstream end of the water supply circuit to a level with high water pressure. In the water supply piping method, a main body case (4) through which a water passage from an inlet side pipe connection to an outlet side pipe connection penetrates, and a communication branched from the water passage and connected to an outer surface of the main body case (4). A pressure reducing valve having a pressure reducing valve mechanism unit (5) having a first connected portion connected to the hole (45) and detachably connected to a connecting portion formed in the main body case (4) is prepared. Then, complete the piping work once in a state where the pressure reducing valve is inserted near the upstream end of the water supply circuit of each household in a hierarchy where it is difficult to determine the necessity of the pressure reducing valve, and the pressure reducing valve is unnecessary. If it is found after the completion of the piping work, the outside of the communication hole (45) A second opening that closes an opening in the surface and has the same structure as the first coupled part;
The closing lid (8) having the portion to be coupled is connected to the pressure reducing valve mechanism unit.
(5) A water supply piping method for an apartment house, which is attached to the main body case (4) instead of (5).
