Please tell me what are the disadvantages of direct flush and siphon toilets?

1. Siphon toilet

It has the characteristics of strong sewage discharge capacity, large cleaning surface and smart toilet seat. Therefore, most toilets, especially conjoined toilets, use siphon type.

The biggest advantage of the siphon type is that it makes less flushing noise, which is also called silent. Siphonic toilets can easily flush away dirt adhering to the surface of the toilet bowl.

2. Direct flush toilet

Utilizes the great thrust formed by the compressed air, flushing speed is fast, the momentum is large, the sewage is discharged strongly, and the speed is fast.

Since the direct flush type uses the instantaneous and powerful kinetic energy of the water flow, the sound of impacting the pipe wall is relatively loud.

Most rear drainage systems are straight flush.

The characteristic of direct-flush toilets is that the diameter of the sewer pipe is large, which can easily flush away larger dirt and save water.

3. Their respective advantages and disadvantages

"Direct flush" and "siphon" are based on their flushing methods. Direct flush toilets have simple flushing pipelines and short paths. The pipe is short and has a thick diameter. It uses the gravity acceleration of water to directly wash away the dirt. The siphon type pipe runs relatively high and slender (the smaller the pipe diameter, the more obvious the siphon effect and the greater the pumping power). Theoretically speaking, direct flush toilets are less likely to clog due to their thicker pipe diameters, but they make greater noise when flushing. Siphon flushing toilets are quieter, but are more likely to clog due to their smaller pipe diameters, and their water consumption is higher than that of direct flush toilets. The flush type is slightly larger, but in actual use, it will not be clogged if used correctly in daily life. The actual water consumption is also related to many factors.

Siphon toilet

Advantages: There is a complete pipe inside, in the shape of an inverted "S", the slope of the pool wall is gentle, and the noise problem is improved; Disadvantages: The water storage area at the bottom of the pool is large and the sewage discharge process is slow.

Direct flush toilet

Advantages: cheap price, small water consumption, good sewage discharge effect, small water storage area in the center of the pool; Disadvantages: loud noise during sewage discharge.

Four: Suitable for house types

Siphon toilet

The "body shape" of the siphon toilet is "short and fat", so it is more suitable for those with larger bathroom areas. House type.

Direct-flush toilet

Compared with siphon toilets, direct-flush toilets are relatively "slender". Therefore, they are suitable for small households where the bathroom area is relatively valuable. First choice.
