What should I do if the main toilet pipe is blocked?

Solution to unclog the toilet 1: Buy some caustic soda, boil water to melt it and pour it into the toilet. Everything will be connected in ten minutes. Solution 2: find a property, they have the responsibility and obligation to help you. Solution 3: dredge the toilet: buy a shovel and dig out the toilet yourself. Solution 4: Use an appropriate amount of oxalic acid (you can also use oxalic acid to clean the toilet at ordinary times, just neutralize it with urine alkali to make the toilet unobstructed). Solution 5: You can buy a loach and put it in the squatting pan, and pour it into the toilet with warm water. When it's hot, the loach will go down desperately to build a toilet. If there is nothing hard, I think the general toilet dredging scheme is 6: old mop, fill the toilet with half water, and then press it into the hole a few times with the mop. Move quickly and let it pass through the toilet by pressure. Solution 7: You fill half the water, aim at the hole in the sewer with a round mop or a brush with round head software ~ thump the toilet hard. Solution 8: Use a relatively long hose. I tried it, and it worked well.
