I can t figure it out when I use it according to the toilet suction

The usage of toilet suction is to press it slowly and then quickly lift it up. By suction and atmospheric pressure, a vacuum is formed inside. But there must be water inside, the effect is better when filled, but pay special attention to dirty water, it is not good to get it on the clothes, and the general blockage will be cleared if you suck it twice.

It's better to hire a professional dredger, and if you can't get it yourself, don't break the sewer pipe below.

All you need is one tool, and that is plastic wrap that is commonly used at home. The specific operation is also very simple, you only need to tear off a few pieces of plastic wrap and wrap it on the surface of the toilet, remember to wrap it evenly, press it a few more times with your hands at the seam to ensure that it is well sealed, and press it more at the place where it is at the seam of the toilet. >>>More

The floor drain you have in your house is gone, and then the gas comes back.

The towel was tightly wrapped around the stick, tucked into the toilet drain, pulled out violently, and repeated several times. If it really doesn't work, then go find someone who specializes in dredging!
