I want to find a phone to connect the sewer.

There are many small advertisements in my own building. There will be a phone number on it.

Bathroom sewer dredge:

First, the waterway dredging agent: it is the best 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, go to the mall to buy professional powder for cleaning pipes, such as (swallowing the king).

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, then you can only try vinegar-grade weak acid at most. Never use the above method. It will take about 3 hours to take effect after filling out these things. If there is no response, you can only find a professional dredging team to force dredging.

Third, put caustic soda into the sewer, and then pour a pot of boiling water into it, not a thermos bottle, but a large pot of boiling water.
