which one should I choose?

What is the difference between a direct flush toilet and a siphon toilet, and which one should I choose?

Toilet purchase is really a science, now on the market a wide variety of toilets, the price gap is also huge, if you do not understand the difference, may be accidentally pitted, now on the market is more common on the two kinds of toilets, one is a direct flush toilet, the other is a siphon toilet, many people do not know the difference between them, do not know how to choose, today we will talk about the difference between the two, which is better.

Let’s start with the direct-flush toilet, which is a post-drain toilet that uses the thrust formed by compressed air. Direct flush type is generally the design adopted by European toilets, which is characterized by a relatively small and narrow water tank, a relatively large excrement outlet in the toilet seat, and a steep slope in the toilet, because this toilet uses the impulse of water to flush away the excrement, so it will be loud when flushing. The advantage is that the flushing pipeline is simple, the path is short, the pipe diameter is thick, and the use of the gravitational acceleration of water can flush the dirt clean, and the flushing process is short.

Let’s talk about siphon toilets, which are divided into vortex siphon and jet siphons. There is a complete pipe in the siphon toilet, the shape is a side-inverted “S”, and the slope of the pool wall is slow, so one of its biggest advantages is that it is quiet and basically silent. It has the characteristics of strong sewage discharge capacity and large net surface, but it also has disadvantages. The siphon toilet must have a certain amount of water to achieve the purpose of flushing, and at least 8 to 9 liters of water should be used each time, which is relatively water-consuming.

The above analysis of the direct flush toilet and the siphon toilet, in order to make it more convenient for everyone to know which one should be chosen, the following is a comparison.

1. Flushing ability

The direct flushing toilet does not have a rebate bend and adopts a straight flush, which is easy to flush down larger dirt and is not easy to cause blockage during the flushing process.

The siphon toilet is easier to flush off the dirt attached to the surface of the toilet, and the flushing effect is more thorough.

2. Water saving ability

The direct flush toilet uses the impulse of the water flow to discharge the dirt in the toilet, generally the pool wall is steeper, the water storage area is small, so that the water power is concentrated, the falling water around the toilet ring is increased, and the water is less.

Siphon toilets have at least 8 liters of water at a time, which is more water-consuming.

3. Anti-odor ability

The straight flush pipe has a simple route, a short path, and a thick neck, so it is easy to smell.

The siphon toilet has a long path and an S curve pipe, which is not easy to smell.

Today’s advantages and disadvantages of direct flush and siphon toilets are introduced here, you can weigh the pros and cons and choose the one that suits you.
