Floor drains are mainly installed in the drainage devices in areas that need a lot of drainage, such as toilets, balconies, kitchens, etc. In a word, for a good floor drain, the drainage speed should be fast enough, which can prevent insects, odors and backflow, and better prevent blockage. It is easy to disassemble and clean, with a fresh and tidy appearance and high appearance value. Its main structure is divided into two parts: main board and inner core.
Characteristics of floor drains of different materials
The materials of floor drains mainly include copper, alloy, stainless steel and plastic.
Copper floor drain: in addition to the high price and easy scratching on the surface, it is beautiful and high-end after chrome plating and wire drawing. It has a good handle texture, corrosion resistance and durability.
Stainless steel floor drain: good stainless steel floor drain is made of 304 stainless steel, which is not easy to rust and has good durability, but it has poor texture and high price
Alloy floor drain: zinc alloy and aluminum alloy are the main materials, with low price. The coating on the main surface is easy to be damaged, and the material is easy to be corroded and aged
ABS engineering plastic floor drain: it will not rust and corrosion, and has high cost performance. As long as it is not immersed in high-temperature water for a long time, it will be used for a long time.
Types and characteristics of floor drains:
Magnetic levitation floor drain: the magnetic levitation floor drain mentioned in the propaganda of all kinds of floor drains is essentially based on the elastic sealing principle, using the magnetic levitation technology to replace the spring force, so as to solve the problem that the spring force changes with time.
Advantages: good sealing performance and long duration.
Disadvantages: high price
Spring / press type spring floor drain: this kind of floor drain places a spring in the inner core. When there is no water or little water, the spring springs up, lifts the seal ring and closes the water channel. The water in the local drain reaches a certain height. Through the action of gravity, the spring is pressed down by the water, and the seal ring is opened to realize drainage.
Advantages: the effect of odor and insect prevention is relatively good.
Disadvantages: the sealing performance will deteriorate after long-term use, and the elasticity will also change. It needs to be replaced every few years.
Gravity floor drain: the cover sheet is sealed by gravity. When there is water passing through, the leak is pushed open by water and closed when there is no water.
Advantages: simple structure, easy maintenance and replacement
Disadvantages: airtightness is easy to be destroyed
Magnet floor drain: built-in magnet, which fits each other when there is no water. When the overflow pressure is greater than the magnet suction, the drainage can be realized.
Advantages: it also has good odor and insect prevention effect and high cost performance.
Disadvantages: some iron impurities are easy to be adsorbed on the magnet, and long-term use will cause the sealing ring to fail to close, which will not play a role in odor prevention.
Water seal floor drain: water seal floor drain is divided into shallow water seal and deep water seal. The internal water is stored in n-shaped pipe or U-shaped pipe to play the role of insect prevention and odor prevention.
Advantages: simple structure and low cost.
Disadvantages: if the stored water is not used for a long time, it will lose the effect of odor and insect prevention.
Precautions for selecting floor drain:
Look at the size: look at the size of the pipe diameter and measure the size of the panel. The size of the panel is generally 10cm. The diameter of the downpipe is generally 50mm, but some are 40mm or 75mm.
Where to use it: the floor drain of the bathtub in the shower room is different from the floor drain of the washing machine
Trap: determine whether there is a trap in your sewer. If there is a trap in the pipeline, buy a floor drain with a trap, and there is no way to enter the water.
Look at the dry and wet: buy mechanical floor drains in the dry area to prevent insects and odors. If you buy water sealed and dry, it will not prevent insects and odors. If mechanical floor drains are used in wet areas, they are easy to break.
Look at the material: don’t treat the copper-plated alloy floor drain as a copper floor drain.
