Observe these methods to troubleshoot leaks in wall-mounted toilets:

  1. Cut off the toilet’s water supply. This is typically found in the wall behind the toilet or close to its base.
  2. To empty the tank, take off the toilet tank lid and flush the toilet.
  3. Verify the washers and bolts holding the tank to the wall. Tighten them if necessary if they are loose or worn, or replace them if necessary.
  4. Examine the gasket and flush valve located at the tank’s base. Replace them if they are broken or soiled, or clean them.
  5. Check for leaks or damage on the water supply hose and valve. If necessary, tighten connections or swap out components.
  6. Look for signs of wear, damage, or faulty installation on the bowl-to-flange gasket. In case the gasket needs to be changed.
  7. Examine the wax ring that secures the toilet’s base to the flange. Replace it if it is worn out or damaged.
  8. Restart the water supply, then top off the tank. At each connection and the toilet’s base, look for leaks.
  9. After troubleshooting, if the leaks persist, you might need to engage a licensed plumber to identify and resolve the issue.

In conclusion, examining, fixing, or replacing numerous elements, such as bolts, washers, flush valves, gaskets, hoses, and wax rings, is necessary to identify leaks in wall-mounted toilets. Consult a licensed plumber for advice if you need it regarding any phase of the procedure.
