How To Solve The Problem When The Toilet Produces Back Odor, Yellowing, Leaking, Slow Drainage, Etc.? Here Is A Detailed Solution Strategy!

In the process of daily use of the toilet, we are often troubled by problems such as odor, yellowing, leakage, clogging, shifting, slow water flow and unclean flushing. When encountering these situations, consumers usually attribute it to the quality of the toilet, but in many cases it is caused by improper use by consumers. How to solve these six types of problems? Here is a detailed solution strategy.



Reverse odor of the toilet


1, one of the culprits of odor is the poor sealing of the flange and pipe mouth of the toilet. During installation, the interface should be sealed with materials such as oil paste embedded in advance at the dumped drain. If the interface is well sealed, the odor may be emitted from the floor tile.

2, the bottom of the toilet sealant is not done tightly, resulting in odor out of return.

3, the toilet around the floor tile is not hooked tight seam, resulting in odor out.

4, the toilet cover is not sealed tightly, causing the odor to return.

5, see whether the water seal of the toilet is enough. Generally for a good toilet, there is a certain amount of water seal stored in the water after flushing, to ensure the isolation of the pipe. If the water seal is destroyed, it is time to change the toilet.

6, during installation, the drainage pipe and the toilet outlet docking are not sealed well, but also easy to have odor run out.



1, if the floor tiles around the toilet have bulging, you have to repair the bulging floor tiles first.

2, smear a circle with glass glue on the bottom edge of the toilet to keep it sealed.

3, After using the toilet, cover the toilet lid in time.

4、Frequently flush the toilet with water so that no stagnant water or spoiled water is stored at the water storage bend.

5, use toilet bowl cleaner as unclogging agent: you can pour an appropriate amount of toilet bowl cleaner into the toilet bowl every now and then, cover the toilet bowl and leave it for a while, then flush it with water to keep the toilet running smoothly.

6, you can place a small cup of balsamic vinegar in the toilet, the odor will disappear. Its validity is six or seven days, and can be changed once a week. Or dry the residual tea leaves and put them into the toilet or ditch to burn and smoke, which can eliminate the bad smell.

Toilet yellowing


The inner wall of the toilet bowl is yellowed. When the toilet is used for a long time, there will be more scale and urine scale, and the inner wall of the toilet will become yellow.



① Old stockings. Spray a foaming stain remover inside the toilet first, and then roll the old stocking on a stick to brush it, and it will completely remove the dirt inside the toilet.

②Coke. Pour carbonated drinks such as Coke into the toilet bowl and brush, the effect is also good.

③Vinegar. White vinegar is acidic, while the odor factor of the toilet is alkaline. When the two meet, there will be a neutralization reaction. In addition put white vinegar in a mineral water bottle, then poke a few small holes at the bottom of the water bottle, then place the bottle normally in the tank. Every time you flush, the vinegar can flow out with the water. This not only can avoid the toilet wall yellowing, but also can effectively deodorize. You can also save water by putting a bottle in the tank, which is a triple whammy.

④ Use 84 disinfectant. 84 disinfectant is mainly composed of sodium hypochlorite (NaClO). Sodium hypochlorite is a strong oxidizing agent that can oxidize most substances and denature them, thus playing a disinfecting role. Sodium hypochlorite reacts chemically with carbon dioxide in the air to produce hypochlorous acid (HCIO), which is an acid and is corrosive. The main component of limescale and urine scale is calcium carbonate (CaCO₃). Cleaning the toilet with 84 disinfectant can not only remove limescale and urine scale, but also play a role in disinfection.

640 3 18

The specific cleaning operation is as follows: pour the 84 disinfectant slowly along the inner wall of the toilet bowl, and brush it with a toilet brush after half an hour, and the toilet bowl will be as bright and clean as new. Then pour some laundry detergent into the toilet, the toilet is not only bright and clean as new and a light fragrance.



Toilet leakage


Generally speaking, there are many reasons for toilet leaks. There are many reasons for toilet leaks. In addition to the poor sealing of the drain valve in the tank fittings, there are also problems such as the quality of the toilet itself is not up to par.

1, poor quality materials. Some manufacturers are bent on reducing production costs. They will choose inferior materials, which will cause the water inlet valve outlet and the inlet pipe itself cracked during injection molding, resulting in sealing failure. Through the drain valve overflow pipe, the water flows into the toilet tank causing “long flow”.

2, the miniature tank accessories. Excessive pursuit of tank accessories miniaturization will lead to floating ball (or floating bucket) of buoyancy is not enough. When the water submerged floating ball (or floating bucket), it still can not make the inlet valve closed, so that the water keeps flowing into the tank, and eventually from the overflow pipe into the toilet caused by leakage. Especially when the tap water pressure is high, this phenomenon is particularly obvious.

640 4 18

3, tank fittings interference. Tank fittings of the agencies in the action will produce interference, resulting in water leakage. For example, when the water tank is released, the float and float rod will affect the normal reset of the flap, resulting in leakage. If the float rod is too long and the float is too large, this will cause friction with the tank wall, thus affecting the free lift of the float, resulting in seal failure and leakage.

4, the drainage valve is not tightly sealed at the connections. Due to poor sealing at the joint, under the action of water pressure, the water of the non-disposable forming drain valve flows into the toilet through the overflow pipe from the interface gap, which causes water leakage. This is the lift-type inlet valve that can freely change its height. If its seal ring and the wall with the pipe is not tight, there will often be leaks.

5, the seal ring is not sealed tightly. If it is after the flush, found that there is a leak at the bottom of the toilet and water is unclear and odor, then basically you can judge that the seal on the drain at the bottom of the toilet is not sealed well. The sealant between the edge of the toilet and the ground is also not sealed tightly. In the case of poor drainage pipes, the dirt flows backwards. You can first confirm whether the drainage pipe is not smooth. If it is not smooth, you have to unclog the pipe first, and then let the product seller to reinstall the toilet seat. Most of this phenomenon occurs soon after the installation of the toilet.

6, the toilet has cracks. If you find that there is water seepage from the surface of the toilet at any time, it is suspected that there may be cracks in the toilet. The test method is: first turn off the water inlet valve, followed by the toilet tank in the water drainage clean. Then use red ink or colored ink added to the residual water in the tank, and let it stay for about 30 minutes to observe whether which place oozes with colored ink. If there is, it can be concluded that the toilet has cracks. This situation is not repairable. Even if it is repaired, it is still a problematic toilet seat. The only way is to replace it.



1, check whether the flush switch is reset. The plastic flush switch of some flush toilets is worn out for a long time and occasionally it will get stuck and cannot be reset. Generally repeat the switch several times and it can be reset. Check whether the rubber gasket of the drain under the ball valve is aging and not sealed tightly, and find that the problem needs to be replaced.

2, check whether the connection between the tank ball float and the water inlet switch is loose, and whether the float is in place and the switch is not closed. If the water inlet does not stop, and it flows out from the upright drain pipe after the water is full, just tighten the float and water valve switch connection. If the rubber ball valve is damaged and not sealed tightly, resulting in a leak, then you need to replace it immediately.

3, the water tank leakage is basically the problem of the drain valve. Check the situation of the water tank outlet plug. If the outlet plug is broken or blocked by foreign objects and the plug is not sealed tightly, it will also cause the toilet to flow. If the water tank is not placed correctly, it will more or less have an impact.

Warm tip: If the interface between the toilet flush and the downpipe is cracked and leaking, it is best not to repair it yourself. It is recommended to ask a professional plumber to repair it.



Toilet blockage

Slightly clogged toilet.

Slight toilet clogging is usually caused by hand towels or sanitary napkins, towel rags, etc. This can be unclogged by directly using a pipe unclogging machine or a simple unclogging tool.



1、 Caustic soda and oxalic acid. In many cases, the toilet will be flushed a few times, and it will pass by itself, especially if it is a soluble or breakable item such as mud or paper. If it is greasy live, then flush a pot of boiling water down to melt it away. Or buy some caustic soda, boil water to melt the caustic soda, pour it into the toilet, and it will pass after ten minutes. Or use the right amount of oxalic acid to unclog (usually you can also use oxalic acid to clean the toilet. It just neutralized with urine alkali to make the toilet unclogged).

2, wire. Use wire to make a hook. Stretch it into the sewer mouth inside the stirring, so that the dirt wrapped around the wire. Then yank out the wire. This will drag the dirt out of the sewer mouth. Or find a half-inch-wide bamboo strip into the toilet to unclog.

3, mop, plunger. Fill the toilet half full of water, and use a round mop or a round-headed soft brush to pound hard against the hole in the sewer. You can also use the old-fashioned mopping handkerchief. After filling it halfway with water, use the mop to press hard into the hole a few times. Move fast and use the pressure to get it through. Or go to the market and buy a plunger. And then a few strokes. Use it once in half a month, the toilet will not be blocked.

4、Drink bottle. Use beverage bottles to unclog. Cut off the bottom of the mouth of a large Coke bottle that you have finished drinking. Put it upside down in the toilet and hold the bottom with your hand and pump it up a few times.

5, air cylinder. Wrap a rag around the cylinder, then pour some water into it and start pumping. After a while, the toilet will be unclogged.

6, hose. Find a section of hose. Connect one end of it to the tap water, the other end is wrapped with a rag and inserted into the sewer pipe, and then turn on the tap water can be. The principle is that the pressure of the tap water is about 4Mpa, so it can completely flush the sewer. Remember not to let the hose leak at both ends to maintain the highest pressure.

7, the toilet apparatus. Use the toilet passer, which is a tool invented specifically for blocked pipes to unclog. The front end of the toilet opener is a flexible spring. The length of the spring is determined by the height of the blockage from the toilet opening. After tightening the screw, press the spring into the pipe until it is unclogged or the dirt is removed.

8、Pipe unclogging agent. Use pipe unclogging agent, which is a powder unclogging product that can be used for unclogging any pipe. Put the unclogging agent into three times in the amount of about 50 grams each time. After an interval of 1-3 minutes, stay for three minutes to flush into hot water after all inputs. Finally, stay for 10 minutes and then rinse with water. After this operation, you should be able to unclog the toilet.


Toilet blockage by hard objects.

While using, you accidentally drop hard objects such as plastic brushes, bottle caps, soap, combs, etc. into the toilet bowl.



This kind of blockage slight can directly use the pipe unclogging machine or simple unclogger to unclog directly. In serious cases, you have to disassemble the toilet to unclog it. The only way to completely solve this situation is to get something out.

Toilet aging blockage.

When the toilet is used for a long time, it is inevitable that scale will build up on the inner wall. In serious cases, it will block the air outlet of the toilet and cause the toilet to drain slowly.



After finding the vent hole, scrape off the dirt to make the toilet water flow smoothly.

Toilet bowl shift


In the renovation, the toilet is usually installed after the bathroom is reserved for the sewage outlet. However, there may be a situation where the two do not match, so the toilet has to be relocated. However, the toilet relocation not only involves the sewerage and waterproofing changes, but also involves the downstairs tenants. If the modification is not good, it may cause poor drainage, which is troublesome.

1, because the toilet pit distance is not suitable, it is necessary to adjust the toilet position. This is the most common problem. In general, you can use the toilet shifter to solve the problem if the pit distance is within 10CM. But the disadvantage is that if it is not handled well, it is easy to block later, so try not to move it.

640 10 12

2, discuss with the downstairs tenants, and change the location of the downpipe. In general, a big elbow is made at the top of the downstairs, so it will not be as easy to block as the toilet lifter. But after changing the location of the downpipe, you must do a good job of waterproofing again, and a good closed water test to ensure that there is no leakage. It is also generally suitable for small distance changes. The premise of this method is easier to implement when the downstairs has not been renovated.

640 11 10

3、Change to a wall-mounted wall-drain toilet. This is a relatively good program, and wall-mounted toilet looks more upscale. But relatively speaking, the wall-hung toilet is generally more expensive.

The toilet is slow, and not clean flush

Reason one.

When installing, the flange interface is installed off, and the downstream flow is reduced.



1, in the purchase of the toilet, be sure to pay attention to the length of the water tank to the tile water pipe is about 30 ~ 35cm. they are 110cm in diameter.

2, when installing the toilet, you have to supervise the whole process. Be sure to make sure that the installation position and the way there are no mistakes, or there will be subsequent problems. If the situation is serious, these have to be dismantled and re-installed.

3, after the installation of the toilet, do not immediately test the water. If you test the water immediately, the cement at the bottom will be washed away, resulting in unstable toilets and water leakage from the bottom. Do not use it immediately either, because the cement at the bottom is not yet dry.

640 14 10


Reason two.

The toilet itself does not have enough pumping power and insufficient water pressure.



1, you can increase the amount of water, such as putting bottles in the water tank.

2, adjust the screw of the inlet valve clockwise to let the water level rise. Note that the water should be at least 10mm away from the overflow orifice of the drain valve.

3, properly adjust the tank water level. Slow flushing only means that the water pipe is a bit blocked, so you just need to unclog it. If the distance from the tank to the toilet flows slowly, check whether there is something blocking the toilet tank to the flush outlet.

640 15 9


Reason three.

Insufficient flushing water, there is a water stoppage and other problems.


1, if the amount of water is not enough, you can take down the tank cover to adjust the amount of water. There are cocks on the top to adjust the length of the plastic rod so that you can control the amount of water.

2, if it still does not work, you can only change the toilet. You can choose the siphon toilet, the effect is good.

640 16 1


Reason four.

Long-term use leads to dirt in the measurement of the downpipe, resulting in smaller water.


You can take down the downpipe, put it into the acid to eliminate the accumulated dirt, and then install it. This way the water will be much faster. If there is a soft object blocked, you can use a soft spiral. If it is something hard, it is best to find a professional company to solve it.


In the process of use, the toilet appears various phenomena. The owner’s anxiety is understandable. After all, most owners have worked hard for half a lifetime for this house. But very often, when the toilet has a reverse odor, yellowing, leaking, clogging, shifting, slow down, flushing is not clean and other problems, it really is not the quality of the toilet! If consumers are still unclear, you can bookmark this article. You can always forward to customers to avoid unnecessary misunderstandings!
