Floor drains, as an important component of the drainage system in residences, have long been neglected by all relevant parties. It is generally believed that floor drains only need to be able to collect the scattered water from the ground, and there is a lack of specialized research on the structure and performance of floor drains themselves. As a result, the most traditional bell-shaped floor drains have been used for a long time and widely until now.

The primary condition for choosing a floor drain is smooth drainage. Not only should it drain quickly, but it should also prevent clogging and backflow. These are the essential basic functions of a floor drain. Generally, the larger the diameter of the drain hole, the greater the drainage flow. Classified by the drainage direction upwards, the water flow direction of the floor drain can be N-shaped, L-shaped, inverted S-shaped, and side-discharge. Among them, the N-shaped drainage is the best drainage method. In addition, when choosing a floor drain specifically designed for washing machines, it is particularly important to pay attention to the drainage speed of the floor drain. This is because the instantaneous drainage volume of a washing machine is very large. If the drainage speed of the floor drain does not meet the requirements, water overflow will occur. Therefore, it is advisable to choose a floor drain specifically designed for washing machines that drains directly.

The second requirement for choosing a floor drain is that it should have good anti-odor function, prevent backflow of odors and pests. Shallow water seals tend to dry out easily, while deep water seals are the safest. However, it is essential to select an improved deep water seal floor drain. When choosing a floor drain without a water seal, it is advisable to select one with a simple structure. The more complex the structure, the more likely it is to malfunction. Generally speaking, in places where water is frequently used, deep-water seal floor drains can be selected. In areas where water is not frequently used and is relatively dry, it is best to use floor drains without water seals.

The third point to consider when choosing a floor drain is that it should be easy to clean, and it is best if it does not require cleaning. Because the floor drain drains sewage from the ground, it often gets entangled with some hair, sludge, sand particles and other dirt, which can easily stick and settle inside the floor drain. If it is not easy to clean, it will clog the pipe over time and affect drainage. The built-in new deep water seal floor drain has a strong drainage force and can wash out most impurities. Even if there are a small amount of residual impurities, since the floor drain core can be conveniently removed, It is also very convenient to clean.

When choosing a floor drain, after meeting the above three requirements, consider the material, style and price, etc. The material should be durable and resistant to corrosion. Stainless steel (304 grade steel) has high strength, copper is corrosion-resistant, and zinc alloy is brittle and prone to cracking over time. The electroplating layer is likely to turn black and develop spots, making it not durable. PVC is the weakest.

At present, the materials of the inner core of floor drains are basically ABS engineering plastics or stainless steel, and their quality and performance are relatively guaranteed. The inner core of the floor drain should be selected to be easy to install and disassemble for convenient cleaning in the future. The structure of the floor drain should be as simple as possible. Complex mechanical structures are more prone to problems due to wear of mechanical components or mechanical failures, leading to the failure of the floor drain's function. When choosing a floor drain, it is also necessary to check whether the material's craftsmanship is fine and whether the surface is smooth and flat. A rough or burr floor drain is prone to dirt accumulation, which will affect its self-cleaning function. Also, under the premise of not affecting the drainage and odor prevention functions, it is advisable to choose thin floor drains as much as possible to make the slope of the bathroom steeper, which is conducive to drainage.
