1 Prepare for safe work
Close the main or local valve, open the lowest faucet to release the pressure, and protect the floor with a bucket and cloths. If electricity is nearby, turn off the corresponding fuse.
⚠ Warning: Do not work on a pipe under pressure or on a boiler connected to electricity. A hidden leak, a damaged main line, and repeated wetting of the wall require a plumber.
2 Determine the condition and the cause
Shut off the water, drain the toilet cistern, and remove the remaining water from the bowl. Check if the connection is accessible without removing the entire bowl.
3 Perform the key check
Remove the old connector gasket, clean the ceramic and sewer outlet extensions, and inspect for cracks and pipe alignment.
4 Perform the repair or maintenance
Moisten the new connector gasket with a lubricant that does not damage rubber, position it without twisting, and test it with several consecutive flushes.
? Tip: Photograph the initial state and change only one thing at a time. This will make it easier to determine what really solved the problem.
5 Test the result
Slowly turn on the water and observe each joint for at least a few minutes, first without load and then at full flow. A wet trace, a drop in pressure, or a sewer smell means that the joint needs to be inspected again.
