Currently, the two popular toilet flushing methods on the market are washdown and siphon. Each of these two flushing methods has its own advantages and disadvantages. Consumers often struggle with this when purchasing toilets. Here we will introduce these two flushing methods in detail so that everyone can make a better choice.

Washdown toilet

Washdown toilets generally have steeper pool walls, smaller water storage areas, and concentrated water power. They rely on the momentum of the water flow to flush away stolen goods.

Therefore, it is easier to flush down larger dirt and is less likely to cause clogging of the toilet.

Siphon toilet?

The siphoning methods of siphon toilets are divided into vortex siphon and jet siphon. Its pipe structure is in the shape of a “∽“. When the drainage pipe is filled with water, a certain water level difference will be formed, and dirt will be drained away with the help of the suction generated during flushing. The advantages of this flushing method are: due to the pipe structure and water storage of the siphon toilet, the toilet with this flushing method has obvious anti-odor effect; the sound when flushing is very small and no noise; the siphon flushing method, It is easy to flush away the stolen goods stuck to the inner wall of the toilet; there are many types of siphon toilets on the market, with a wide range of choices.

This flushing method also has some disadvantages: the diameter of the siphon drainage pipe is small, usually about 5 to 6 centimeters, and is easy to block; the siphon toilet requires a certain amount of water to flush away the stolen goods, and has poor water conservation. It consumes 8 to 9 liters of water each time.

Toilet appearance

Toilets fall into the category of ceramic products. A high-quality toilet will have a smooth and flawless surface, free of irregularities. The ceramic glaze is fine and smooth, without any defects. Premium toilets are generally fully ceramic, exhibiting a noticeable weight when lifted by hand.

The appearance of the toilet should harmonize with other fixtures in the bathroom and align with the overall decorative style of the bathroom.

Toilet flushing test

Conducting a flushing test when purchasing a toilet is a necessary step.

Some toilets tend to splash water during use, and this should be taken into account during the purchase. The primary factor influencing toilet splashing is the height of the water seal. To avoid splashing, attention should be paid to the toilet’s water seal height, with the optimal range typically between 55 to 60 millimeters.

Bathroom Drainage System and Rough-in Distance

Before purchasing a toilet, it is essential to understand the drainage system and the rough-in distance of the bathroom.

The rough-in distance refers to the distance between the toilet’s outlet and the wall behind the tank.

The permissible error should not exceed 1 centimeter to prevent installation issues.

Providing this information to the seller during the purchase process helps ensure that the selected toilet is suitable for the specific bathroom layout.
