System principle:
        With floor drainage system is a drain pipe branch does not cross the floor, connected to the drain through the floor supervisor in the same floor drainage system.
        Currently drainage layer technique There are two main forms:
(1) In concealed mounting system as the main features wall-row drainage layer technology, the current European and American countries use more that way, it is the most widely used way;
(2) to drain the sump of the main features of the lower plate with the drainage layer technology, in Japan and other countries to use more that way.
        Compared with the traditional approach barrier drainage, drainage layer scheme is the most fundamental change in the concept of the rational distribution layer through the pipeline, and to rid itself of the shackles of the adjacent floor room to avoid the horizontal drainage pipe Since the lower space occupation caused a series of troubles and risks, including property rights are unclear, noise, leakage risks, space limitations, etc., while using a wall-mounted plumbing fixture, on the ground there is no longer any health corners, has become particularly easy to clean sweep.
System advantages:
       (1) Health: drain pipe branch does not cross the floor, avoiding the upper to the lower water through leaking pipes, reducing the possible spread of disease, but also solve the horizontal drainage pipe in the rainy day surface condensation problems.
       (2) Independent: pipeline maintenance and overhaul at this layer does not interfere with lower household.
       (3) Safety: Avoid repeatedly piercing the concrete floor is conducive to the integrity of the floor, reducing the possibility of fire spreading.
       (4) Spacious: to avoid the ceiling WeiChu between increased interior headroom.
       (5) Sound: drainage channels with concealed installation have better sound insulation, reducing the flow of water between the inner drainage layer of noise propagation.
       (6) free: drain pipe branch construction does not require setting aside hole, sanitary ware can be personalized decoration.
Disadvantages different drainage patterns table:

System components:
        Same floor drainage system is mainly composed of HDPE piping systems, concealed installation systems, sanitary ware and trap and other components.
HDPE pipe and fittings
HDPE high-density polyethylene pipe using PE100 grade materials, has excellent resistance to UV, anti-aging, impact resistance, superior corrosion resistance, excellent performance of anti-acid rain, to ensure the smooth wall, clogging.
Complete specifications of pipes and pipe fittings to meet various project needs; the pipe has good toughness, air tightness and anti-aging properties;
Suvi off
        Sovent (Sauvignon de) is a gas-water mixing drainage, generally used in high-rise buildings each layer branch / riser connections, can connect 6 drain pipe branch. Its specially designed internal structure can effectively control the drainage riser degree of mixing gas and water, thus achieving efficient single riser with floor drainage system.
Concealed sanitary installation system
        The system is the same floor drainage system is an important part of the concealed installation system for all sanitary pipes, tanks and mounting brackets integrated in false walls, wall to reveal only a wall-mounted plumbing fixture as the entrance of the drainage layer, to leave the bathroom unlimited creative space.
