What should I do if the toilet runs against the current in heavy rain?

When it rains heavily, the toilet may be flooded due to the increased load of the drainage system. If the toilet backfires, the following measures can be taken:

1. Turn off the water valve in the bathroom first: If you can find the main water valve in the bathroom, you can turn off the water valve first and stop the water supply to prevent the water from flowing backwards.

2. Use a toilet dredge: If it is anti-water caused by blockage, you can use a toilet dredge to dredge it. Put the dredge in the toilet and punch holes up and down several times to increase the drainage pressure and help clear the blockage.

3. Clean the drain: If the drain is blocked, you can gently clean the dirt and deposits around the drain with a long-handled tool (such as a pipe dredge).

4. Use chemical dredging: If the above methods are ineffective, you can try to use some chemical dredging to dissolve the blockage. According to the product instructions, pour in a proper amount of chemical dredging agent, wait for a while, and then rinse with clear water.

5. Seek professional help: If you can't handle it yourself, you can contact the relevant pipeline maintenance service provider or property management party for professional help.

Please note that if the anti-water situation is serious, it is suggested to take measures as soon as possible and find out the reasons, so as to avoid the excessive water level in the bathroom causing greater sewage flooding and damage. At the same time, cleaning and maintaining the drainage system regularly at ordinary times can reduce the occurrence of blockage.
