1. When installing a new pipe, it accidentally falls into a foreign object or is blocked due to an installation error. Generally, the pipeline dredge is used to dredge or replace the pipeline directly. 2. Some pipelines will scale after being used for a period of time, which will make the inner diameter of the pipeline thinner and affect the normal sewage discharge. In this dredging, the pipeline must be cleaned with high-pressure water to remove the dirt on the inner wall of the pipeline, so as to enlarge the inner diameter of the sewage pipeline.
Dredging method
First, the waterway dredging agent: it is a product on the market. This product is especially effective for removing the blockage caused by hair, grease and paper. Widely used in restaurants, hotels, families and other vegetable sinks, wash basins, bathtubs, floor drains, toilets and other blockages. No damage to sewer pipes (including PVC pipes) and electroplating layer.
Usage: Clear the accumulated water in the washbasin or sanitary ware, and pour 50- 100G of this product into the sewer. If there is no water in the sewer, please add half a cup of clear water. At this time, the pipe is boiling. After about 20 minutes, rinse with plenty of water.
Recommended dosage: washbasin, bathtub, floor drain-100g, vegetable sink -—200G, toilet -—400G.
Second, the practice of dredging the sewer blockage in the bathtub (mainly caused by the hair left during bathing). Because the drain of the bathtub has a cover, it can only be dredged from the floor drain. Go to the store and buy a 8 yuan (about 6 mm in diameter) hand-cranked spiral steel wire, push it down from the floor drain until you feel a foreign body with your hands, and then gently pull it out while shaking it, so that the blocked hair and other dirt will spin on the spiral steel wire. Problem solved. Very convenient. If there is no cover at the drain of the bathtub, it will be more convenient (never use hydrochloric acid, for one thing, it will pollute the environment, for another, it will be very dangerous to human body, and for another, the pipeline will be corroded and perforated by hydrochloric acid for too long, which will make the trouble even greater).
Third, set fire to the sewer, and then pour a pot of boiling water into it, not a thermos bottle, but a big pot of water.
4. If you have watered the children with iron pot water and asked the workers to pass with iron branches, but later you don't go into the water, it is not suitable to use iron branches again, for fear that the corroded canals will be penetrated. It can be replaced by thick rattan. Ten eight-inch nails can be nailed to the rattan head, and the impurities are loosened while being put in, then the concentrated alkali solution is poured in, and then the rattan is pushed out. If this continues many times, it will have an effect. In addition to thick vines, you can also go to the hardware store to buy a spring ditcher, which is more effective. Salt, white vinegar, straws, etc. What ordinary people use can't be used.

5. Get some baking soda and vinegar.
Six, other methods
1, animal fat plug: If it is oily, it is recommended to use boiled water. Of course, it would be better if you could buy concentrated sulfuric acid. If something is blocked, you can only use the special tool for cleaning pipes mentioned upstairs.
2, cement plug: 70% hydrochloric acid can not be found, 35% are sold everywhere, you can try. Add a little flour to act as a corrosion inhibitor, and urotropine. The corrosion of steel can be reduced.
3. Buy a 2m-long spring steel pipe dredging tool in the market, bend it at 10-20 degrees on its head 1-2cm, dredge it back and forth at the sewer entrance and exit, and rinse it with water.
Other answers:
1, rinse with boiling water. Most sewage plugs are oil plugs, and boiling water can dissolve them.
2. The solution is to call housekeeping and cure the disease.
3. If it is oily, you can use 20% Sufangda water to get through. If something is blocked, you can only use the special tools mentioned in the building. 4. The simple method is as follows:
(1). Wash the waterway with a large pot of boiling water.
(2). Then stab it with thick iron wire several times until the running water runs out.
(3) Repeat (1) and (2) if necessary.
Seven, go to the mall to buy professional cleaning pipe powder, such as (swallowing the king), the composition seems to be lime powder.
8. If your sewer is made of new PVC, you can suck the water up with a vacuum pump first, and then fill it with strong vinegar or caustic soda, industrial vinegar and industrial alkali, but don't mix them, just use one. If you don't know or are not sure, or it must be an old-fashioned iron pipe, you can only try it with vinegar-grade weak acid. Never use the above method. After filling out these things, it will take about 3 hours to take effect.
Nine, put in the yellow locust, or add some irritating things like washing powder or salt, then cover it, and the sewer pipe will be connected in an instant!
10. Green method of dredging sewer: pour 1 cup of washing powder into the blocked sewer, and then pour 3 cups of hot water. If this doesn't clear the sewer, pour 1 cup of vinegar into it.
Eleven, log dredging sewer method: insert a log with a diameter close to the inner diameter of the sewer pipe, put a certain amount of water in the pool, and quickly pump the log up and down without interruption. Under the action of suction and pressure, the blocked dirt in the pipeline will be washed away.
If the above methods can't be dredged, you can ask a professional sewer dredging company to solve it.
Clean the kitchen
1, look for yourself first, but pay attention to PVC or cast iron. Buy a 2-meter pipe dredge at the stall, make several bends at the head 2 cm, put it in the outlet dredge while draining, put it in while shaking, and then put it in the inlet dredge while draining. Just repeat it several times! At the same time, it will be dredged every other week. If professionals come, you can use manual methods first, don't pour water, or enclose the pool to prevent water from splashing. Of course, other things should also be put away. Also, you should make sure to remove it in a short time, otherwise it will smell very strong.
2. Find a professional dredging company, and they will definitely solve this problem. 3. Find an iron wire with a diameter of 0.5- 1mm and a length of 3-4m, fold it in the middle, then twist it into a strand, then bend both ends in different directions at one side of the single end, then put this end into the sewer pipe, grab the other end and twist it while screwing it in. You can't twist it when you encounter resistance. If you pull it directly, some sundries can be hooked out, and it can be basically dredged after repeated times. If you can't hook anything on your wire and it's unblocked, then the problem may not be your home, but the pipe downstairs may be blocked.
3, the sewer is full of water, press it down with a cork, and then lift it hard, which will form a certain pressure and pumping force, which may wash away the blocked debris; But if the plug is too dead, I'm afraid it's just a serpentine tube. You can also use the wire mentioned above, but this is expensive and difficult to handle. Find someone to dredge it. In addition, there is a kind of stuff called pipeline dredging agent, which is sold in supermarkets. You can try it.
