With the development of society, more and more styles of toilets are being produced, but what is the most important for a toilet? The flushing method of the toilet.

Question 1 – How many types of flushing methods?

Toilet flushing methods are mainly divided into washdown flushing type and siphonic flushing type. The upgraded version of the siphonic is jet siphon and vortex siphon.

Question 2 – How do washdown toilets and siphonic toilets work when they flush?

First of all, the flush toilet, we can intuitively see that its sewage pipe is straight and the pipe is very thick. The principle is to directly use the gravitational acceleration of water to flush the dirt down.

Then the siphon toilet, its pipe is S-shaped, after the sewage pipe is filled with water, a certain water level difference will be generated, forming suction to discharge the excrement.

Question 3 – What is the difference between a washdown toilet and a siphon toilet in terms of experience?

First of all, the washdown toilet flushing method is actually the least likely to accumulate dirt, but it is really noisy, and only those who are not afraid of disturbing their families at night will go for it. The siphon toilet, its noise is relatively small, and the water cover can be relatively large, but the disadvantage is that it is a little difficult to encounter the giant excrement.

Question 4 – Which is the better deodorization effect of washdown toilet or siphon toilet?

From the perspective of the deodorization effect, the storage surface of the washdown toilet is relatively small, which will lead to scaling on the toilet surface, so the deodorization effect will be worse. The siphon toilet has its own water seal, and the storage surface is higher, so it has a good anti-odor effect.

Question 5 – in addition to the above two methods, are there any improvements in toilet flushing?

Based on the previous questions, we can draw a conclusion that a good toilet flushing should have a high impulse and no noise. Therefore, we have developed siphon jet flushing mode and siphon vortex flushing mode. A spraying pipe is added under the horizontal plane at the bottom of the pool wall to increase the impact on the force and dirt through the spraying effect of the jet. As the contact area is increased and the sewage discharge range is widened, the noise in the whole sewage discharge process will be reduced a lot.

Another flushing method is called vortex siphon, which is also a branch under the siphon. Its flushing pipeline is designed below the urinal, and the water outlet is located at the diagonal edge of the bottom of the urinal. When the water surface reaches a certain value higher than the sewage outlet, a siphon phenomenon will occur to complete the sewage discharge.

Question 6 – Should you buy a washdown or siphonic toilet?

In fact, this question really hits the deepest part of the author’s heart. According to the current products on the market, most of the products are siphonic. However, I think there is still a little gap between the siphonic impulse and the straight impulse. But in many cases, when we buy a toilet, there are still many factors that need to be considered. The most critical point is to see which toilet is suitable for the plumbing design at home, and then make a choice.

As for which one is better, it is still closely related to each person’s home environment. We need to understand our housing structure, usage needs, decoration style, and other factors in detail before making a decision.
