If it smells like sewage when you flush, the issue often lies with worn out toilet seals or a problem in your vent pipe. A broken seal can let sewer gas enter your home, while a blocked or improperly installed vent pipe can't eliminate gases outdoors. To resolve this, check and replace the wax ring under the toilet or inspect the vent pipe for any obstructions or damage. Consulting a professional plumber may be best for accurate diagnosis and repair.
