What should I do if the floor drain in the bathroom smells bad when it blows?

Now a lot of floor drains.

It's all like this, not only the wind, but even when the range hood is turned on at home, the floor drain will smell upwards - the floor drain has no anti-odor ability, and the air flow speed on the surface of the floor drain will increase (the pressure will decrease), and the smell in the floor drain will come up.

Why does the floor drain smell back then, the floor drain almost does not encounter this situation, in the final analysis, it is the floor drain pipe that has a problem. In the past, floor drains would have a trap – from the downstairs ceiling.

This bend. <>

As long as the water in the trap does not dry (it will dry out if the floor is not drained for a long time), the water will block the smell of the upwell. However, there is a disadvantage in the trap, which is that it affects the drainage speed of the floor drain.

Therefore, with the pursuit of ground drainage speed, the floor drain trap (you can also understand it as saving construction costs) has been gradually eliminated. At present, only the one under the toilet still retains the trap in the residential drain.

Without the anti-odor device, the floor drain will reflect the smell in the following two situations:

The best solution to the floor drain odor is to change the floor drain - there are many odor-proof floor drains at present, and the more famous ones are T-shaped floor drains and U-shaped floor drains.

When the pressure in the room is low- For example, if the wind is blowing indoors, the air velocity on the surface of the floor drain increases, which will cause the air pressure to decrease. Or turn on the range hood and pump it up directly with external force.

When the pressure in the pipeline is high- For example, if there is a user upstairs draining water, the addition of water causes the pressure in the pipe to increase.

In both cases, the relative pressure in the pipes will be higher, so the gas in the pipes will rise from the floor drain in our home. Of course, what also enters our home is the smell in the pipes.

SolutionTo solve this problem, the most critical way is to supplement the anti-odor device of the sewer - if you can't prevent odor directly on the pipe, we will start with the floor drain.

Change the floor drain: When decorating, a floor drain with an anti-odor core is directly installed, which is the best choice to prevent odor. It's just that you need to pay special attention to the quality of the deodorant core when choosing a floor drain, otherwise it will break down after two years, and it is no different from not installing it directly.

In addition, the deodorant core must be selected in a universal size and removable. So that after damage in the future, it can be replaced in time. (It is difficult to replace the floor drain after the decoration is completed, so only the anti-odor core can be replaced after damage.) If the size of the deodorant core is special, I am afraid that you will not be able to find the accessories. ）

Install an anti-odor core: If it has been renovated, you can choose to install an anti-odor core on the floor drain of your home. Put the floor drain on top of the grate.

Take it off, and you can directly see the floor drain core (almost all floor drains have a core, but the difference between anti-odor and non-odor-proof) -

Blocked: Regardless of whether there is an anti-odor core or not, and no matter what kind of anti-odor core, it is almost impossible to adapt to a dry environment - when there is no water in the drain, the general anti-odor core will lose its effect (the same is true for homemade anti-odor cores).

So for houses that you don't live in often, the best way to prevent odor is to plug it. You don't need to block it tightly, a piece of cardboard is enough.

If you want to solve the problem of smelling back when the floor drain in the bathroom blows, the most critical way is to supplement the anti-odor device of the sewer - if you can't directly prevent odor on the pipe, we will start with the floor drain. You can consider changing the floor drain, directly install a floor drain with an anti-odor core when decorating, and you can also install an anti-odor core, if it has been decorated, you can choose to install an anti-odor core on the floor drain of your home, but the best anti-odor method is to block the anti-odor core. You don't need to block it tightly, a piece of cardboard is enough.

The solution to the smell of leakage.

The best way is to change a floor drain - there are many odor-proof floor drains at present, and the more famous ones are T-shaped floor drains and U-shaped floor drains.

The former relies on a magnet in the floor drain and the sealing strip around the magnet. When there is water, open the magnet to drain the water, and when there is no water, the magnet is engaged, and the sealing strip seals the floor drain to prevent backsmelling.

You can buy toilet supplies that are specially designed to prevent floor drains and smell online, which can deal with the odor of the bathroom well, and you can also often open the window to ventilate, and there are also commonly used incense in the bathroom to cover up the smell.

Change a floor drain. It is possible that the pipe of your floor drain is not long enough, so it will be odorous, you can put a sewer seal anti-odor core.

As soon as you enter the bathroom, will the smell on your face greatly affect your quality of life? What should I do if there is a smell in the bathroom?

As soon as the floor drain in the bathroom is windy, it smells bad at home, and the home is particularly smelly, how to solve this problem? Regarding the problem of floor drain odor, I have encountered this kind of problem before, so let's talk about some solutions to the floor drain odor! Method 1:

Keep the sewers clear; To know that there is definitely a reason for the backsmell of floor drains, the first thing we should check should be whether the sewer is unobstructed and whether there are any foreign objects affecting the normal drainage of the sewer. If there is a blockage, it is recommended to check whether there is any anti-odor after dredging the sewer, if there is still a water sealing principle, use a thin plastic bag to fill the water, seal the bag mouth, and put it on the mouth of the sewer to cover it tightly, which plays a role in sealing the odor. In addition, it is best to keep clean water in the bowl-shaped water reservoir structure at the sewer mouth at the same time, which is more effective in preventing odors from coming out.

Method 2: Choose a floor drain with good performance; In order to increase the floor height and reduce the cost, the anti-drain under the floor drain has been canceled, and a new type of anti-odor floor drain has been adopted to ensure that the sewer odor does not come out. These odor-proof floor drains are often made of PVC materials, far less beautiful than the stainless steel and copper floor drains sold on the market, many owners have replaced the floor drains that look beautiful and the actual quality is unqualified when decorating, and the water seal of the floor drain is very shallow, and the smell of the sewer pipe cannot be isolated, so it leads to a peculiar smell in the bathroom, so it is recommended not to change, and to replace the floor drain with high odor-proof performance.

Method 3: Fresh-keeping bag deodorization method; Open the fresh-keeping bag under the room, stuff two-thirds of the fresh-keeping bag into the sewer, leave the remaining fresh-keeping bag outside, and then put the floor drain into the card slot and cover it, you don't need to change the fresh-keeping bag frequently, it is more trouble-saving and labor-saving, and the effect of deodorization is also good. It is also a good way to cover the drain when it is not used, and you can use plastic bags or waste towels to block the drain opening, which can not only block the entry of odors but also block certain bacteria.

Not to mention frequent cleaning, regular flushing of the floor drain with water, or air freshener to dilute the smell of the floor drain. You can learn from the methods I mentioned above, there are some difficulties, but effective inhibition is still possible, if your floor drain has anti-odor phenomenon, hurry up and take action.

You can cover the floor drain with a thick plastic sheet to prevent the backflow of odors, you can also place deodorant or incense in the bathroom, and the most important thing is to ensure that the ventilation is dry and the windows are opened frequently.

First of all, you have to check whether the sewer is unobstructed, whether there are foreign objects in it, if there is a blockage, you must dredge the sewer in time, and check whether it is a floor drain with an anti-odor smell, and some floor drains, its own anti-odor effect is not particularly good, at this time you can go to the store to buy a good anti-odor effect.

The problem of floor drain must be solved, and the floor drain needs to be modified, so that this problem can be effectively solved.

When the floor drain in the bathroom is windy, it smells bad, how to solve it? When it comes to bathroom decoration design, one place is crucial, and that is the floor drain. The floor drain of many homeowners will have anti-odor conditions, and the air quality at home is difficult to guarantee.

Make a large bowl and pour in the right amount of baking soda and vinegar and mix the two together. Next, use a long brush to remove as much of the stain as possible from the drain and quickly pour the mixture of baking soda and vinegar directly into the pipe.

The chemical reaction between baking soda and vinegar effectively removes the greasy substance from the pipes and removes them quickly. If the floor drain is more seriously blocked, resulting in a serious anti-odor problem, caustic soda can be used for dredging. Start by preparing a few tablets of caustic soda, throw them down the drain, and pour some hot water into them.

Caustic soda will undergo chemical changes when it encounters oil stains, the temperature will rise rapidly, the oil will dissolve and be discharged with hot water, so that the pipes will be unblocked, the floor drain will be well drained, and the natural smell will not be reversed. In order to prevent the next floor drain from clogging, we must do a good job of prevention in time. You can prepare a plastic bag, fill it with more than half of the water, and tie the bag to the floor drain.

This is the use of the principle of water sealing, which can well block the floor drain and prevent odors from entering the air. When showering, you need to remove the plastic bag. Choose a crisper bag, fill it with water and tie it tightly.

Place a crisper bag with water on the floor drain and the smell will fade. However, plastic bags are thin and can easily be scratched by the edges and corners of porcelain plates or floor drains, so be careful when using this method. Add an appropriate amount of disinfectant water to the basin, add water and stir well, soak the towel in the basin and wring it out.

Then, place the wrung towel on the floor drain so that the smell of the floor drain is gone. Place the water-soaked tea on gauze and sew a hand-sized tea bag with a needle and thread.

Then, place the tea bag on the floor drain, the smell of the tea bag will mask the smell of the floor drain. Use scissors to cut open the bottom of the plastic bag so that it slides up and down into a plastic cover. He then opened the drain and slid one end of the bag into the drain, leaving about a third of the bag on the ground.

Then, open the plastic bag and cover the floor drain in the slot so that the smell is gone.

You can install a cover to prevent odor, spray some disinfectant things in this place at ordinary times, and put some activated carbon in the bathroom, so that it can be a good solution.

First of all, check whether our floor drain has a water seal, you can replace the floor drain or buy a floor drain mat or find a roof ventilation system.

I think the best thing to do is to replace it with a one-way floor drain so that there is no bad smell.

Now, in order to meet the demand for large-flow drainage, many places have eliminated the trap of ordinary drainage pipes during construction, and only the toilet has been retained. Therefore, the floor drain is easy to smell - especially when there is wind, it can no longer be called "odor", we all know that the drainage pipe of the general floor drain and the drainage pipe of the toilet are connected, share the drainage main, and connect the floors in series, straight to the roof, there is an exhaust outlet. The function of the exhaust port is to expel the dirty and odorous air from the pipe, and at the same time balance the air pressure when the pipe is drained.

Use a pipe cleaning tool to check whether the sewer is blocked, and if it is blocked, you can use a special debris suction tool to drag up the hair and debris to make the pipe run smoothly. Or use baking soda powder and vinegar, the substances produced after the neutralization reaction of the two can be cleaned up, which is to ensure that there is enough atmospheric pressure in the sewer pipe to remove the sewage, but when the wind blows, the sewer pipe will increase the air pressure through the air outlet cap, and the dirty gas in the sewer pipe will be discharged into the home through the floor drain, forming a foul odor.

When you don't need the floor drain during the day, put this plastic filled with water on top of the odorous floor drain, because the density of water is very high, and it has fluidity and variability, and these two properties can be used to prevent the floor drain from smelling back. Remove the garbage from the floor drain first. Prepare a bowl of water first, add an appropriate amount of vinegar to the water, then add two spoonfuls of baking soda, and then pour it into the drain.

It is necessary to install a floor drain on the ground to effectively drain the wastewater. The kitchen and bathroom floor drain will cause an anti-smell situation for some reasons, making the house smelly. To solve the problem of floor drain odor in the kitchen and bathroom, only a simple method can be solved.

Silicone anti-odor floor drain core is absolutely inexpensive. Get it for a few bucks. Be sure to pay attention to choosing the right one.

Carefully observe and measure, so you can consider changing the floor drain and opening more windows for ventilation.

Cover the drain so that odors from the pipes don't come out through the drain.

It can be isolated with an odor-proof floor drain, which can pass through the water and close itself to isolate the sewer smell.

I think you can find a professional master to deal with it, and I guess I can't handle it myself.

Change an anti-odor floor drain: Install an anti-odor floor drain with a deodorizing core immediately during interior decoration, which is the best choice to avoid odor transfer. It's just that when choosing an anti-odor floor drain, you must pay great attention to the quality of the deodorant core, otherwise it will break down after 2 years, and there is no difference between it and not installing it immediately.

In addition, the deodorant core must be selected with universal specifications and detachable type. It can be dismantled and replaced immediately after it is destroyed in the future. (It is difficult to replace the floor drain after the interior decoration is completed, so the only way to replace the deodorant core after the destruction is completed.)

If the deodorant core has a unique specification, you may not be able to find spare parts. ）

Retrofit deodorant core: If you have already decorated, you can choose to install a deodorant core for your home floor drain. Take off the grate on the top of the anti-odor floor drain, and you can immediately see the floor drain core (almost all odor-proof floor drains have a core, but the difference between deodorization and non-odorization) At this time, put the purchased deodorant core into the sewer pipe (don't worry about it falling down, the deodorant core can be stuck on its own), and you can cover the grate again.

Self-made deodorant core: Customers who rent a house are likely to be unwilling to pay for a deodorant core, so they will make their own deodorant core. The same is to take out the floor drain core, and then coil it around the side of the floor drain core with a fresh-keeping bag, and then put it home.

Or take a balloon and put it on the core of the floor drain and make an opening underneath. If the fresh-keeping bag or the earth is stained with water, it will automatically stick together, which is equivalent to plugging the odor-proof floor drain. When water comes in, the water will open the sticky mouth again, ensuring the success of the drainage pipe.

Plugging: Regardless of whether there is a deodorant core or not, and no matter what kind of deodorant core, it can hardly be integrated into the dry natural environment - there is no water in the local drain, and the general deodorant core will lose its actual effect (the same is true for self-made deodorant cores). Therefore, for houses that you don't live in often, it's best to deodorize them or plug them.

You don't have to block it tightly, just put a piece of cardboard in it.
