What are the disadvantages of traditional floor drains?

The traditional water-sealed floor drain has a bell-type structure, that is, a buckle bowl is buckled on the mouth of the sewer pipe to create a "U"-shaped water trap to achieve the purpose of sealing, so it is called "water seal".

1. Environmental pollution (1) The water seal height is not enough, most are only 10-20mm, and it is easy to dry up, causing the odor in the drainage pipe to return into the room.

Even if the water seal is renovated and deepened to 50mm, it will not delay the odor-free time for a few days. Moreover, deepening the water seal will make the hydraulic conditions worse and deposit dirt more serious; (2) In summer or windy weather, the air pressure

Constantly changing, the positive pressure in the pipe will cause the bowl to float, and the odor will overflow from the water; while the negative pressure in the pipe will destroy the water seal, the pipe will lose its barrier, and the odor will overflow into the room; 2

, bacteria spread in the dark and humid sewer pipes, and the wastewater carries a large amount of small solid impurities (such as sediment, hair, cloth strips, paper scraps, peeling biological mucosa, etc.), which will stick to the "U"-shaped drain trap,

Over time, these residues become a breeding ground for germs and odors. Water-sealed floor drains are unable to stop cockroaches, black-winged insects and other pests and most germs that breed in sewer pipes, seriously polluting the indoor environment and endangering the health of your family.

Healthy; 3. Poor self-cleaning ability, it is easy to block the drain trap, and it is easy to stick and deposit dirt, which is unhygienic and very difficult to clean; 4. The drainage speed is slow and the water flow must pass through an extremely narrow circular gap.

Only by making two 180° sharp turns can it be discharged.
