What Is Sewer Drainage?

A sewer is a kind of urban public facility, which refers to a pipe that drains sewage and rain from a building; it also refers to an underground passage that drains sewage and rain from a city, factory, or village.

The sewer is a city

The sewer is a public facility in the city, and it has been around since ancient Rome. They picked up some waste at the garbage dump to make a simple "house" to live in, and beds, wardrobes, and bookcases were all picked up. Later the Idararia left the Romans the most magnificent sewer in the ancient world: the Cloaca Maxima. Around the 6th century BC, the Idararia excavated a sewer that drained into the Tiber River. Its main road was more than 16 feet wide, and was subsequently expanded for the Romans. The seven branches of the sewer flow through the city streets and eventually merge into the main sewer Maxim sewer.

By 315 AD, there were more than 140 public toilets in Rome. Sociable Romans developed public toilets into places for entertainment and relaxation. Like public baths, for a small fee, people can gather in public toilets and engage in natural behaviors such as gossiping with neighbors, planning parties, discussing politics, or engaging in business.

Sewer pipe clogging is a very common problem in daily life. Sewer dredging is generally divided into several types: 1. When foreign bodies are accidentally dropped into the newly installed pipes or they are blocked due to incorrect installation, pipe dredge machines are usually used to directly dredge or Replace the pipes; 2. Some pipes will scale after using for a period of time, making the inner diameter of the pipes thinner and affecting the normal drainage. Such dredging must use high-pressure water to clean the pipes, remove dirt from the inner walls of the pipes, and expand the inner diameter of the sewer pipes. Sewage dredging is widely used in restaurants, hotels, homes, etc. to clear up the sinks, washbasins, bathtubs, floor drains, and toilets.

Sanitary sewer dredging:

I. Waterway dredging agent: It is the best product on the market at present. 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 50-100G of this product into the sewer pipe. If there is no water in the sewer, please 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 drain100G, vegetable sink200G, toilet400G.

Second, the method of dredging the blocked sewage in the bathtub: (mainly caused by the hair left in the bath and causing the blockage). As the drain in the bathtub has a cover, you can only clear it from the floor drain. Go to a small store and buy a hand-wound spiral steel wire for 8 yuan (about 6 mm in diameter). From the floor drain, push it downward while rocking until the Feel the foreign body, and then gently pull it out while shaking, dirt such as clogged hair will spin on the spiral wire, the problem is solved. very convenient. It is more convenient if there is no cover in the bathtub. (Do not use hydrochloric acid. First, it will pollute the environment. Secondly, it will easily cause danger to the human body. Third, the pipeline is too long to be corroded and perforated by hydrochloric acid. The trouble is even greater.)

3. 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 boiling 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 nt go to the water, then it is not suitable to use iron branches again. Can use thick rattan, rattan head can nail ten mouth eight inches long iron nails, one side extended and stirred, loosen the debris, and then filled with concentrated alkali solution, and then push the rattan out 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 tricks

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 clogging, then you have to use the special tool for cleaning pipes.

2, cement plug: 70% hydrochloric acid is not found, 35% are sold everywhere, you can try it. Add a small amount of flour in it to act as a corrosion inhibitor. Ulotropine is the best. Can reduce the corrosion of steel.

3.Go to the market and spend ten dollars to buy a 2 meter long spring steel pipe dredging tool. Make a 10-20 degree bend at 1-2 cm on its head, and dredge back and forth at the entrance and exit of the sewer. Rinse with water.

Seven, go to the mall to buy professional cleaning powder medicine, such as (Swallow King 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 and use only one. If you do nt know or are not sure, or if it is an old-fashioned iron pipe, then you can only try it with vinegar-grade weak acid at most. Do not use the above method. After filling these things, it will take effect in about 3 hours If there is no response, you can only find a professional dredging team for forced dredging.

Nine, put a small yellow cricket, or add some irritating things such as washing powder or salt, and then cover the lid, the sewer 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.

1. First look through yourself, but pay attention to PVC or cast iron. Buy a 2-meter pipe dredger on the stand, make some bends at the head 2 cm, and put water into the dredger at the outlet, shake it into the dredger, and then enter the dredger at the water inlet. Dredge while draining, can be repeated several times! At the same time, dredging should be carried out every other week.

If a professional comes, you can use artificial methods first, instead of pouring water, you can also surround the pool to prevent water splashing. Of course everything else needs to be put away. Also you have to make sure to clear it in a short time, or it smells great.

2. Find a professional dredging company, they can definitely solve this problem.

3. Find a wire with a diameter of 0.5-1 mm, 3-4 meters in length, fold in half from the middle, then twist it into a strand, and then bend the two heads in different directions on the side of the single head, and then extend this end to In the sewer pipe, grab the other end and twist it in one direction while going inward. If you ca nt reach the resistance and you ca nt reach it, pull it out. Do nt twist it at this time. The debris can be hooked out, and it can be cleared several times. If your iron wire can't hook things, it is unblocked, then the problem may not be your home, it may be blocked by the pipes downstairs.

4. The sewer is full of water, press down with a leather plug, and then mention it violently. This will form a certain pressure and pumping force, which may flush the clogged debris away; but if it is too dead I am afraid that only a serpentine tube is acceptable. The iron wire mentioned above can also be used, but this is expensive and not easy to get. It is best to find someone to clear it. In addition, there is a Dongdong called pipe dredge. It is sold in supermarkets You can also try. ^[2]
