What to do if the toilet sprays outward, my house is on the 4th floor

Find the merchant who bought the toilet to replace the die inside, there should be a problem.

Find the worker who gets through the sewer to see where the problem is, if it is his own plumbing problem, let him fix the pipe, and there is another possibility that it is possible that the upstairs bathroom is used up and throws the paper directly into the toilet and causes the pipe to be blocked, in this case, he must pay someone to clean the pipe, and then he will also learn a lesson, and your problem is solved... Typing is super tiring, begging to adopt.

Find the property immediately, explain that the main pipe downstairs or your house is blocked, let people fix it. Or your family will get into other people's wastewater. The first aid measure is to buy a "wire rope" that leads to the toilet pipe, as thick as a little finger. Make a pass first.

Turn off the water valve in the toilet and get someone to fix it.

There is nothing you can do about stressful things, you need to find a property to solve it.

Close the inlet valve first, and then find someone to repair it.

It may be jammed, go through it yourself, if it doesn't work, find a master.

Explain that the sewer downstairs is blocked.

Your question is a bit vague.

Looking for a toilet repairer, still have time to ask questions here?
