Which flushing solution is better for siphon Toilet  PK straight flush toilet?

Siphonic toilets are easy to flush away dirt adhered to the surface of the toilet, while straight flush ceramic toilet  have a larger diameter of the drain pipe and are prone to flushing out larger dirt. They each have their own advantages and disadvantages, so it is important to consider them comprehensively when making a purchase.
1. Seeking a balance between water conservation and flushing rate

However, due to the focus of the topic of water conservation, a new question has arisen: whether to use direct or siphon water conservation while maintaining momentum?

Whether a toilet saves water depends on two aspects, one is the water tank? One is sitting in a bucket. The difference between the sitting bucket part is the difference between straight and siphon toilet bowl. Represented by some European brands, they are all direct flushing, using British design standards. The characteristic is that the flushing pipeline is simple, the path is short, and the diameter is thick, usually between 90 to 100 centimeters. With the acceleration of water gravity, it is easy to flush away dirt. And the siphon type pipeline runs 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, there is a greater demand for water quantity. People who install siphon toilets at home will find that when flushing, they need to first release water to a very high level, and then the dirt can only flow down with the water. Its design structure determines that it must have a certain amount of water. To achieve the level of flushing, at least 8 or 9 liters of water should be used at once. If the flushing volume is forcibly reduced to 3/6 liters, it will be found that the flushing rate is not enough. Some consumers in the market are now reporting that the 3/6-liter toilet cannot be flushed clean, which is due to this. A toilet requires coordination. If only a water-saving water tank is used, but a large water storage bucket is paired with it, it will be difficult to achieve true water-saving.
