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, the connection pipe is bound from each faucet installed at the entrance of each room to supply cold and hot water to the laundry room, balcony, bathtub, wash basin and 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 leaks 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.

By the way, the wall-mounted faucet box is a common pipe type made of metal or synthetic resin connecting the hot and cold water pipe passing through the faucet and the faucet, so each connection pipe is separated one by one when checking or repairing the inside of the faucet box After the next work, the work is not only inconvenient, but also takes a lot of work time because it must be combined again in reverse order.
