First, sewer drainage is usually seen:
1.When newly installing pipelines, accidentally falling into foreign bodies or being blocked due to incorrect installation, generally a pipeline dredging machine is used to directly dredge or replace the pipelines;
2. After some period of use, some pipes will be scaled, which will make the inner diameter of the pipe thinner and affect the normal drainage. Such dredging must use high-pressure water to clean the pipe, remove dirt from the inner wall of the pipe, and expand the inner diameter of the sewage pipe.
Second, dredging methods
I. Waterway dredging agent: It is an excellent product on the market. This product is especially effective for clogging and dredging caused by hair, oiliness, paper, etc. Widely used in restaurants, hotels, homes, etc. to clear the sink, washbasin, bathtub, floor drain, toilet blockage. Does not damage sewer pipes (including PVC pipes) and does not damage the plating layer.
How to use: Remove the accumulated water in the sink or ware, and pour this product into the sewer. If there is no water in the sewer, add half a cup of water. At this time, the pipe was boiling. Rinse with plenty of water after about 20 minutes.
Recommended dosage: washbasin, bathtub, floor drain 100G, vegetable sink 200G, toilet 400G.
Second, the method of dredging the sewer of the bathtub is blocked (mainly caused by the hair left when taking a bath). Because the sewer in the bathtub is covered, it can only be dredged from the floor drain, and go to a small store to buy an 8 yuan hand Shake the spiral steel wire (about 6 mm in diameter) and push it downward from the floor drain until you feel a foreign body in your hand, and then gently pull it upwards while rocking. The clogged hair and other dirt will spin on the spiral steel wire. The problem is solved easily. It is very convenient. It is more convenient if the drain in the bathtub is not covered. (Do not use hydrochloric acid. First, pollute the environment. Second, it is easy to cause danger to the human body. Once again, the pipeline is over Long and easily perforated by hydrochloric acid, the trouble is even greater).
Third, put the caustic soda into the mouth of the sewer, and then pour a pot of boiling water into it, not a warm pot, but a large pot for water.
4. If you have used water to pour water, please ask workers to use iron branches to pass through it, but then you do n’t go to the water. You can use thick rattan. The rattan head can be nailed with ten or eight inches long iron nails. It can be stirred while extending into the side. If it lasts several times, it can be effective. In addition to rough rattan, you can also buy spring channelers from hardware stores for better results. Salt, white vinegar, straws, etc. used by ordinary people are not effective.
Fifth, get some baking soda and vinegar.
Six other methods
1. Animal oil blocking: If it is oily, it is recommended to use boiling water, of course, if you can buy concentrated sulfuric acid, the effect is better. If something is clogged, then only the special tools for cleaning the pipes mentioned above can be used. 35% are sold everywhere, so try it out. Add a small amount of flour in it to act as a corrosion inhibitor. Ulotropine is good. Can reduce the corrosion of steel.
2. Go to the market and buy quick money to buy a 2 meter long spring steel wire pipe dredging tool. Make a bend of 1-2 cm on its head, dredge back and forth at the entrance and exit of the sewer, and rinse with water.
3. Other methods:
a. Rinse with boiling water, most of the sewage plugs are greased, and the boiling water can be dissolved.
b. A good way is to call housekeeping and get rid of it.
c. If it is oily, you can use 20% Sufangda water. If it ’s blocked, you can only use special tools
4. The simple method is as follows:
(1). Use a large pot of boiling water to flush into the watercourse
(2). Then use a thick iron wire for a few times until the boiling water runs out
(3). Repeat (1) and (2) if necessary
Seventh, go to the shopping mall to buy professional cleaning pipeline medicine powder, such as (Swallow King), the ingredients seem to be lime powder and so on.
8.If your sewer is made of new PVC material, then you can use a vacuum pump to suck up the water above it, and then fill it with concentrated vinegar or caustic soda, industrial vinegar, and industrial alkali, but don't mix them and use only one. If you do not know or are not sure, or if it is an old-fashioned iron pipe, you can only try it with vinegar-grade weak acid. Do not use the above method. After filling these things, it will be effective in about 3 hours. If there is no response, you can only find a professional dredging team for forced dredging.
Nine, put in a small scutellaria baicalensis, or add some irritating things such as washing powder or salt, and then cover the lid, the drain pipe will pass instantly!
10. Green way to clear the sewer: Pour 1 cup of washing powder into the blocked sewer, and then pour 3 cups of hot water. If this does not clear the sewer, pour another cup of vinegar into it.
Eleven, the log dredging method: insert a log with a diameter close to the inner diameter of the sewer pipe, insert 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 tube will be washed away.
