Generally, pipes for water supply and hot water supply are installed in buildings such as apartments, officetels, and hotels. The cold and hot water pipes introduced from the outside are guided to a distributor installed at the bottom of a sink, a built-in cabinet, a dressing room, and the like. It is connected to each demand such as laundry room, balcony, toilet, bathroom, boiler room and utility room.

Looking at the cold and hot water pipes from the distributor to each demand destination, the outer surface is a pipe passing through the inside of the curved pipe (aka bellows-shaped) pipe, passing through the floor of the room or living room while surrounded by the protection pipe, Heading to the bathroom, connecting the connection pipe from each faucet installed at the entrance of each room to supply cold and hot water to the laundry room, balcony, bathtub, wash basin, toilet bowl.

The floor buried method of the faucet box is not easy to renovate after the operation, for example, if the cold or hot water pipes are broken or leaked due to freezing during use, check the cold, hot water pipes or faucet buried in the floor with the naked eye It is difficult to do this, and in the end, it is necessary to dismantle the floor or the floor, and then take a look at each one, and after reconfirmation or renovation, it is inconvenient to reclaim the floor. Wall-mounted methods that directly bury walls are emerging.
