Diagnosis

A leak at the base of your toilet typically indicates that the wax ring, which creates a seal between the toilet and the floor, has been compromised or has failed. This seal is essential for preventing water and waste from escaping. Ignoring this issue can result in floor damage and the potential for mold.

Tools Needed

  • Adjustable wrench
  • Putty knife or scraper
  • Bucket
  • Old towels or rags
  • Gloves
  • New wax ring kit
  • Screwdriver (Phillips and flathead)
  • Level

Warnings

  • Always turn off the water supply to the toilet before starting any work.
  • Wear gloves, as you will be handling potentially unsanitary materials.
  • Be careful when lifting the toilet; it is heavy and can cause injury or damage if dropped.

Step-by-Step Instructions

  1. Locate the water shut-off valve, usually behind the toilet tank, and turn it clockwise to stop the water flow.
  2. Flush the toilet to empty the tank and bowl. Hold the flush lever down to drain as much water as possible.
  3. Lay down old towels or rags around the toilet's base to absorb any residual water.
  4. Disconnect the water supply line from the toilet tank.
  5. Unscrew and remove the nuts from the bolts located at the base of the toilet.
  6. Carefully rock the toilet gently from side to side to break the seal, then lift it straight up and off the floor.
  7. Set the toilet down on old towels or a piece of cardboard to protect your floor and the wax ring.
  8. Using a putty knife or scraper, remove the old wax ring from both the bottom of the toilet and the floor flange.
  9. Thoroughly clean the area around the floor flange and the toilet's base.
  10. Position the new wax ring onto the floor flange, making sure it is centered.
  11. Gently lower the toilet back into place, pressing down slightly to ensure the new wax ring is properly seated.
  12. Reattach and tighten the nuts onto the toilet bolts. Be careful not to over-tighten them, as this can crack the porcelain.
  13. Reconnect the water supply line.
  14. Slowly turn the water supply back on and inspect the base for any signs of leakage.
  15. Flush the toilet again and perform another check for leaks around the base.

Troubleshooting

  • If the toilet still leaks, ensure the toilet bolts are snug but not over-tightened, which can crack the porcelain.
  • Check that the floor flange is level and not damaged; a damaged flange may require professional repair.
  • Verify that the new wax ring was correctly seated and that the toilet was placed evenly on it.

Preventive Tips

  • Avoid using excessive force when flushing or cleaning the toilet.
  • Periodically check for any signs of water around the base of the toilet.
  • If you notice any wobbling, tighten the toilet bolts slightly to prevent stress on the wax ring.
