1. Common causes
Sealant failure
Why: When a toilet is installed, sealant is usually applied between the toilet bowl and the floor. If the sealant is not of good quality or deteriorates after a long period of use, it may cause the seal to fail, resulting in water leakage.
Solution: Check that the sealant is in good condition. If the sealant is found to be aged or broken, the sealant needs to be reapplied.
The bottom of the toilet bowl is broken
Reason: The bottom of the toilet bowl is in contact with the ground for a long time, which may be damaged due to wear and tear, impact, etc.
Solution: Check the bottom of the toilet bowl for breakage or cracks. If so, the bottom of the toilet bowl needs to be replaced with a new one or repaired.
Drain problems
Cause: A ruptured drain or loose connection may cause water leakage at the connection between the toilet bowl and the floor.
Solution: Check the drain for cracks or looseness. If necessary, replace cracked drains or loosely fastened joints.
Installation issues
Causes: Improper installation of the toilet bowl can lead to water leakage, such as untightened screws, incorrect placement of the drain, etc.
Solution: Recheck and adjust the installation position of the toilet bowl to make sure all screws are tightened and the drain is in the correct position.
2. Inspection and maintenance
Turn off water sources
Before any repair operations, first turn off the water source to avoid further leakage.
Disassemble the toilet
If possible, remove the toilet from the floor first to make it easier to check for the problem.
Check the sealant
Observe if the sealant is aged, broken, or peeled off. Reapply sealant if needed.
Check the drains
Check the drain for cracks or looseness. Replace or tighten drains if necessary.
Reinstall
After all repairs have been made, reinstall the toilet, making sure all parts are properly installed.
Testing
After all repairs have been made, a test is performed to make sure the toilet is no longer leaking.
Please note that the above are just some of the common causes of water leaks and how to fix them. In the actual repair process, adjustments and repairs may also need to be made on a case-by-case basis. If you are not familiar with the repair operation, it is recommended to seek the help of a professional maintenance personnel.
