The floor drain prevents odor

Method One: Try to choose floor drains with a deep water storage bend. Floor drains with a water seal height of 5CM have the best anti-odor effect.

Method Two: Once the water in the water trap of the water-sealed floor drain dries up, it will no longer be able to prevent odors. Therefore, in dry seasons, it is necessary to sprinkle more clean water on the floor drain.

Method Three: Since floor drains need to be pre-embedded in cement and are not suitable for replacement, it is recommended to choose all-copper floor drains. When choosing stainless steel, it is advisable to select those with thicker zinc to prevent rusting. PVC is prone to aging and should not be used.

Method Four: When draining the washing machine, use a dedicated floor drain for the washing machine. This type of floor drain has a rotary control and can be turned off by rotating when not in use. Do not use a washing machine with a water seal that is too deep, otherwise the water flow will be too fast and it is easy to overflow.

Introduction and installation knowledge explanation of floor drains and anti-odor floor drains

Cleaning of floor drains

A. Cleaning tools: buckets, brushes, water pipes, rubber gloves, etc.

B. Cleaning method: When disassembling for cleaning, be sure to remove the debris on the partition first to prevent it from being thrown into the sewer and causing clogging. Then, use a brush to scrub each component of the floor drain. You can also use some cleaning agents for cleaning. Then

Disinfect and deodorize the sewer, and then reinstall the floor drain.

Maintenance of floor drains

The maintenance of floor drains mainly involves regular cleaning to keep them clean and tidy. Then, avoid throwing any debris into the floor drain. Regularly remove impurities to prevent clogging and ensure the smooth operation of the floor drain. The U-shaped water collector in the floor drain should be kept filled with water to prevent pests such as cockroaches and foul odors from invading. It should also be disinfected regularly.

Precautions for floor drain installation

The centerline of the main core of the floor drain must coincide with the centerline of the pipe to ensure that the product always maintains the highest drainage efficiency.

2. The floor drain should be slightly lower than the ground to prevent water accumulation, and it must be located at the lowest point of the floor.

3. Throughout the entire decoration process, all kinds of foreign objects should be avoided, especially cement slurry entering the pipes through the floor drain, which can prevent the pipes in the home from being blocked due to the entry of decoration waste.

4. Please handle the packaging of the floor drain properly to avoid environmental pollution.

Installation method of floor drain

Remove the old floor drain, that is, remove the grate and the bowl on the original floor drain to expose the sewer pipe. Use an electric saw to remove the old old-fashioned floor drain. Take out the old floor drain and see that it has been corroded and cannot be used anymore.

2. Remove the small panel and the inner core that have leaked locally.

3. Apply an appropriate amount of white cement mortar respectively to the inner edge of the original floor drain opening and the lower edge of the large panel of the local drain, and cover them on the original floor drain opening. Note that the plane should be slightly lower than the ground and the drainage outlet should be aligned with the sewer opening (this is very important).

4. Insert the inner core into the floor drain frame and tighten it, then cover it with the grate. Please make sure it is completely dry for 12 hours before starting to use.

Installation of floor drain

First: Trim the reserved drainage holes to make them perfectly match the purchased floor drain, as real estate developers usually provide relatively large reserved drainage holes when delivering the property. Among them, the opening diameter of the floor drain grate should be controlled between 6 and 8mm, which can prevent the entry of hair, sludge, sand particles and other dirt.

Second: It should be noted that the number of water inlets for multi-channel floor drains should not be too large. Multi-channel floor drains are products developed in recent years. One main body usually has 3 to 4 water intakes (for the washbasin, bathtub, washing machine and floor drainage). This structure not only affects the drainage capacity of the floor drain, but also does not conform to the actual design situation. Therefore, the number of water intakes for a multi-channel floor drain should not be excessive. Two (the floor and the bathtub or the floor and the washing machine) are fully sufficient.

The floor drain prevents odor

I. Phenomenon Analysis

There is no anti-odor floor drain installed in the bathroom.

2. If the bathroom is not used for a long time, the water in the water trap of the anti-odor floor drain will gradually evaporate and lose its deodorizing function.

Ii. Solutions

Anti-odor floor drains must be installed in the bathroom. Anti-odor floor drains are divided into two types: sealed and water-sealed.

Sealing: The lid is held in place by the attraction of a magnet to achieve the effect of isolating odors.

Water seal: It is equipped with a water trap. Through the sealing effect of water, it prevents the smell from the sewer from rising back, providing a better sealing effect.

2. Try to choose floor drains with a deep water storage bend and a water seal height of 5CM for the best anti-odor effect.

3. Once the water in the water trap of the water-sealed floor drain dries up, it will no longer be able to prevent odors. Therefore, in dry seasons, it is necessary to sprinkle more clean water on the floor drain.

4. As the floor drain needs to be pre-embedded in the cement and is not suitable for replacement, it is recommended to choose an all-copper floor drain. When choosing stainless steel, it is advisable to select those with thicker zinc to prevent rusting. PVC ages easily and should not be used.

5. When draining the washing machine, a dedicated floor drain for washing machines should be used. This type of floor drain has a rotary control and can be rotated to close when not in use. Do not use a washing machine with a water seal that is too deep, otherwise the water flow will be too fast and it will easily overflow.

Advantages and disadvantages of different floor drains

Water-sealed floor drain: It relies on the water in the trap to prevent odors. Disadvantage: There must be stored water in the floor drain; otherwise, it will not have the effect of preventing odors.

2. Eccentric block type: That is, a sealing gasket is used, and one side is fixed with a pin. The sealing is achieved by the principle of gravity eccentricity. However, the sealing is not tight, and the pin is prone to damage, leading to failure.

3. Spring type: It is divided into top-spring type and bottom-spring type. The pop-up type is to press the cover plate, which pops up. Press it again and it will return to its original position. The downward spring type uses a spring to stretch the sealing gasket at the lower end of the sealing core for sealing. As the spring is made of boron-iron, it is prone to rust, its elasticity gradually weakens until it fails, and its service life is not long. In addition, the spring is prone to entanglement with hair and fabrics and is not easy to clean.

4. Magnet type: It uses the magnetic force of two magnets to attract the sealing gasket for sealing. Due to the poor quality of surface water, such as when washing items or scrubbing the floor, some iron impurities will adhere to the magnet. After a period of time, the impurity layer will cause the sealing gasket to fail to close. In addition, due to the effect of the Earth's large magnetic field, the magnetic force will gradually weaken.

5. Mechanical type: No water seal is required. It does not rely on external forces such as springs or magnets. Instead, it opens and closes the sealing gasket by utilizing the principle of gravity in reverse. There are no obvious defects.

Classification of floor drains

Water anti-odor floor drain: The most traditional and common one, it mainly utilizes the sealing property of water to prevent the spread of odors. In the structure of floor drains, the trap is the key.

2. Sealed anti-odor floor drain: It refers to adding an upper cover to the floating cover to seal the floor drain body and prevent odors.

3. Three-proof floor drain: The most advanced anti-odor floor drain to date. It installs a small floating ball at the lower end of the floor drain pipe. On a daily basis, it uses the water pressure and air pressure in the sewer pipe to hold the ball up, making it completely close to the floor drain opening, thereby playing a role in preventing odor, insects and water overflow.

Characteristics of floor drain

1. Anti-backflow odor, anti-backflow water, anti-bacteria and anti-pest. When water flows in, the sealed window at the bottom automatically opens for direct drainage. After the drainage is completed, the sealed window will automatically close, forming a complete seal. Even if it is not used for a long time, harmful gases, sewage, bacteria and pests below the floor drain cannot come up.

2. The pore size of the anti-clogging filter panel is 6mm-8mm, which can block large impurities. The drainage channel is straight-through in shape. Fine impurities are directly washed into the sewer with the water flow and will not accumulate or clog.

3. Fast drainage: The water flows out directly without any backflow. The drainage volume can reach 1.15L/S. Even when the washing machine drains a large amount of water instantaneously, there will be no backflow.

4. Easy to clean, it can be used as a cleaning port. The connection between the sealing core and the main body is screw-in type. According to the usage situation, it can be removed at any time for cleaning. When cleaning, remove the sealing core and the sewage can be directly swept into the floor drain without clogging.

5. Conical detachable drainage pipe for washing machines nThe conical detachable drainage pipe for washing machines is suitable for drainage pipes of various diameters. It is both aesthetically pleasing and practical, ensuring that the drainage pipe will not fall off during drainage, eliminating your worries.

Selection of floor drains

Water seal is one of the important features of floor drains with water seals. When choosing, it is necessary to understand whether the water seal depth of the product reaches 50mm.

Second, side-wall floor drains, floor drains with mesh frames, and sealed floor drains generally do not have water seals. Most anti-overflow floor drains and multi-channel floor drains are equipped with water seals. When choosing them, it is necessary to understand the specific information provided by the manufacturer clearly.

For floor drains without water seals, a trap with a water seal depth of no less than 50mm should be installed on the drain pipe of the floor drain. This component can be configured by the floor drain manufacturer or set up by the construction unit that installs the floor drain.

Fourth, the height of the floor drain grate surface can be adjusted, with an adjustable height of no less than 35mm, to ensure that the floor drain surface elevation is level with the ground after the floor decoration is completed. The installation of waterproof wing rings on the floor drain is to meet the waterproofing requirements when the floor drain is installed on the floor slab.

V. For floor drains located in underground garage car passages or load-bearing areas, the strength of their grates should be capable of meeting the corresponding load requirements.

Six. The structure of the floor drain with water seal should be reasonable and smooth, and the debris in the drainage should not easily settle down. The cross-sectional area of each part for water passage should be larger than that of the discharge pipe, and the minimum clear width of the flow channel cross-section should not be less than 10mm.

The anti-odor principle of floor drains

1. Direct drainage is adopted, with water flowing directly into the sewer pipe. The drainage rate is 1.3 liters per second (the national standard is 1.0 liters per second), which avoids the accumulation of dirt in the trap of the water-sealed floor drain and the secondary pollution caused.

2. It opens and closes by the gravity of the water flow itself. It opens when there is water and closes when there is no water. Stepless speed regulation, completely sealed; Gravity is the source and the performance is stable. It won't seal floor drains like springs or magnets, where the elastic force or magnetic force gradually diminishes and eventually fails.

3. All the joints of the sealing core, sealing gasket and washing machine casing are equipped with sealing rubber rings to ensure that odors and pests have no chance to take advantage. Double filtration with metal covers and plastic grates prevents large debris from clogging the sewer pipes.

4. Specialized drainage sleeve for washing machines, suitable for drainage pipes of various diameters of washing machines, solves the problem of large instantaneous drainage volume of washing machines and water overflow to the ground. After removal, it can be used as a regular floor drain.

5. Easy to clean. The insertable sealing core only needs to be rotated out and scrubbed in water. The main body is entirely made of 304 stainless steel or high-quality brass, carefully processed and multi-layer electroplated. The sealing core is made of high-quality engineering plastic, which can withstand high temperatures up to 80℃, is corrosion-resistant, environmentally friendly and has a long service life.
