After the sewer has been used for a long time, it is inevitable that there will be debris clogged. I always push the wooden handle rubber pump up and down habitually. This method often leaves sequelae.
Because the pump goes down on time, it will push the garbage deep into the pipe; then when it is pulled up, it may not necessarily suck out the garbage, especially if it is like falling hair, it will form a big ball over time, and the more you press it up and down, the more it will heal. Pushing it deeper into the pipe will make it more difficult to remove the debris.
The exact way is to fill the bucket with clean water first, turn the pump gently, and after sticking to the drain, just pull it up and suck it out without pushing it down, and you can dredge it without leaving any hidden dangers. sewer.
