Which flushing solution is better for siphonic toilets or direct flush toilets?

Siphonic toilets are easy to flush away dirt adhering to the surface of the toilet bowl, while direct flush toilets flushing closet have large pipe diameters, which can easily flush down larger dirt. They have their own advantages and disadvantages, so you should consider them comprehensively when purchasing.
1. Seek a balance between water saving and flushing rate

However, due to the focus on the topic of water saving, people have come up with a new question: Is direct flush or siphon water saving under the premise of maintaining flushing force?

Whether a Toilet Complete saves water depends on two aspects, one is the water tank? The other is the bucket. The difference between the bucket part is the difference between direct flush and siphon. Some European brands are represented by direct flush, which adopts the British design standard. The characteristics are simple flushing pipes, short paths, and thick pipe diameters, generally 90 to 100 cm in diameter. The gravity acceleration of water can easily flush away dirt. The siphon pipe is very high, long and thin, because the smaller the pipe diameter, the more obvious the siphon effect and the greater the pumping force. But inevitably, the requirement for water volume is high. People who install siphon toilets at home will find that when flushing, water must be released to a very high water level first, and then the dirt can go down with the water. Its design structure determines that a certain amount of water must be available. In order to achieve the level of flushing, at least 8 liters or 9 liters of water must be used at a time. If the flushing volume is forcibly reduced to 3/6 liters, it will be found that the flushing rate is not enough. Now some consumers in the market report that 3/6 liter toilets cannot be flushed cleanly, which is due to this. Toilets require coordination. If only a water-saving water tank is used, but it is matched with a bucket with a large water storage volume, it is difficult to achieve real water saving.

 

2. Pipeline area determines whether it is easy to block

The key to the water-saving performance of the toilet lies in the coordinated design and installation of the entire flushing system. In the past, the reason why the flushing volume of toilets could not be controlled was mainly because the toilets were assembled from loose parts, and the water-saving performance of each part could not be coordinated and unified. There are relatively few varieties of direct flush toilets on the market. The performance of this type of toilet is better than that of siphon toilets. However, there are relatively few such molds of domestic manufacturers, so this situation has occurred in the market. Moreover, there is no return bend in the design of this toilet, and it adopts direct flushing. It is not easy to cause blockage during flushing compared with the siphon toilet.

The diameter of the siphon toilet is only about 56 cm, which is about three times worse than the direct flushing area when converted into water flow area, so it is very easy to get blocked during flushing. Some people joked that families who install siphon toilets must have two supporting equipment: a wastebasket and a plunger. Because if toilet paper is thrown directly into the toilet, it is easy to get blocked; and the aftermath work is naturally indispensable for the plunger.

 

3. Each has its pros and cons. Recognize your needs

So why does the siphon toilet occupy a mainstream position in the current bathroom market? First of all, brands such as American Standard and TOTO that adhere to American standards entered the Chinese market earlier, and people have formed a buying habit. And the biggest advantage of the siphon toilet is that the flushing noise is small, which is the so-called quiet. Since the direct flush type uses the instantaneous strong kinetic energy of the water flow, the sound of impacting the pipe wall is not very pleasant, and most of the noise complaints about the bathroom are directed at this.

After market research, it was found that people do not care much about the noise during flushing, but are more concerned about the water filling noise after people stand up, because this will last at least a few minutes. Some toilets sound like a sharp whistle when filling the water. The direct flush type cannot avoid the flushing sound of the direct flush, but they emphasize the silence when filling the water. Moreover, after using the toilet, people hope that the flushing process is as short as possible. The direct flush type can be effective immediately, while the suspension process of the siphon type is also quite embarrassing. However, the siphon type has a high water seal, so it is not easy to smell.

In fact, no matter what flushing method of the toilet is chosen, there will be pleasant and annoying places. From the perspective of water saving alone, the direct flush type is definitely better, but if there are elderly people who like quietness at home, you have to consider it. Although the siphon type is not perfect in combining water saving and flushing, it has been very mature in the domestic market, and it is quiet and odorless. So what style should you choose in the end? You have to adapt to local conditions and choose the superior products that you value most.

4. What else should you look at besides flushing toilets

Look at the appearance: Split toilets are generally small in size and suitable for small bathrooms; one-piece toilets have smooth lines and novel designs, and there are many styles to choose from. In addition, the return bend at the bottom line of the toilet is sealed, which provides convenience for future toilet cleaning; in addition, it is important to observe the height of the toilet tank. The higher the water tank, the greater the flushing force, and the better the flushing effect.
Look inside: In order to save costs, many toilet manufacturers work hard on the inside of the toilet. Some return bends are not glazed, while others use gaskets with low elasticity and poor sealing performance. Such toilets are prone to scale blockage and water leakage. Therefore, when purchasing, put your hand into the sewage outlet in the toilet and touch whether it is smooth inside. The ones that feel smooth are glazed, and the ones that feel rough are not glazed. The gasket should be made of rubber or foam plastic, which has high elasticity and good sealing performance.

Look at the glaze: The toilet is a ceramic product, and the quality of the glaze on the outside of the ceramic is very important. A toilet with a good glaze is smooth, delicate, and has no flaws. It can still be as smooth as new after repeated washing. If the glaze quality is not good, it is easy for dirt to hang on the walls of the toilet.
