What is same-layer drainage and what is non-same-layer drainage?

The drainage horizontal branch pipes are arranged on the drainage layer or outdoors. The drainage method where the appliance drainage pipe does not pass through the floor is drainage on the same floor.

The drainage method in which the appliance drain pipe needs to pass through the floor and be connected to the drainage cross branch pipe is a non-same floor drainage method.

The drainage cross branch pipe is a drainage pipe on the second floor, and the drainage pipes on different floors are arranged under the roof of the first floor.

Same-floor drainage refers to the horizontal drainage pipes and their components on this floor, which do not pass above the residents below.

Therefore, the slabs of the kitchen and toilets on each floor need to be cast at a lower elevation. Therefore, when the riser tee, the toilet trap, etc. need to be repaired, it will not affect the normal life of the residents downstairs; in case of leakage in the pipeline during use,

, without endangering the lower levels.

This is the advantage. The disadvantage is that lowering the slab (lowering the elevation for pouring) will increase the labor cost.

Extended information: Compared with the traditional interlayer drainage treatment method, the most fundamental change in the concept of the same-floor drainage scheme is to use the rational layout of pipes on this floor to completely get rid of the constraints between adjacent floors and avoid the intrusion of the lower floor by drainage horizontal pipes.

A series of troubles and hidden dangers caused by space, including unclear property rights, noise interference, hidden dangers of leakage, space limitations, etc. At the same time, with the use of wall-mounted sanitary appliances, there are no longer any sanitary dead corners on the floor, making cleaning extremely convenient.

Same-floor drainage is a novel technology in the bathroom drainage system. The drainage pipes are laid on this floor. A special water-sealed pipe fitting is used to replace the many P-bends and S-bends. The overall structure is reasonable, so it is not prone to blockage.

, and easy to clean and clear. Users can personalize the location of bathroom sanitary ware according to their own hobbies and wishes.
