The toilet not the toilet in the old building has a blocked drain.

I'll teach you a very good method, tried and tried: two steps.

First, if you want to do a good job, you must first sharpen your tools.

There has to be a tool: a piston aspirator. This may not be very easy to buy in the market right now. You can go to the grocery and local products store to go around. Be sure to buy it with a mouth larger than your floor drain.

2. Sealing engineering.

Then put it on the floor drain and pump it repeatedly. One thing to note is that all parts must be kept sealed. There are mainly two parts of the air leakage:

One is that the piston is not tight, and the other is the connection between the floor drain and the suction device. The method is to seal with water: fill the upper part of the piston with water, so that the piston part is sealed, and then put water on the part where the floor drain mouth meets the suction device, and seal this part as well, and you can use a towel to make a "dam" so that the water will not be lost.

After the completion of the "project" of the above seal, it will be pumped, and it will be done in three or four strokes at most.

Off topic: It is best not to poke with iron wire, which will destroy the anti-corrosion layer in the pipe, which will not only not work, but also make the pipe rot faster. Cast iron pipes are used in old houses, and the oil layer adhered to them will play a role in protecting the pipes from rust.

Spend 50 yuan to find a professional sewer dredge person to dredge it. If you dredge it yourself, don't break the pipe, and it will be a big trouble. More cleaning tips can be searched: Qianye Cleaning for inquiry.

Buy a spring dredger, that is, a rocker, with a handle on it, turn directly, and when it reaches the bend, it goes in directly, and pulls it out when it doesn't move. Be forceful. If it is hair and leaves, it will definitely pull out.

Larger things inside can also be pulled out. Mine just used it. It works.

50 yuan for it. It's okay to buy your own unclogger. It's only more than 20 yuan!

It seems that only professional ones can be lifted, can you try it with a toilet first, maybe it will work.
