Step-by-Step Guide to Replacing a Toilet

Step 1: Turn Off the Water Supply
Locate the shut-off valve behind the toilet and turn it clockwise. Flush the toilet to drain the tank and bowl. Use a sponge or towel to soak up any remaining water.

Step 2: Disconnect the Water Line
Use your adjustable wrench to loosen the nut connecting the supply line to the tank. Have a bucket ready to catch any drips.

Step 3: Remove the Old Toilet
Unscrew the nuts from the closet bolts at the base of the toilet. Gently rock the toilet back and forth to break the seal, then lift it off and set it aside.

🚨 Pro Tip: Toilets are heavy – get help if needed, and place it on a towel to avoid scratching the floor.

Step 4: Remove the Old Wax Ring
Use a putty knife to scrape off the old wax ring from the flange. Clean the area thoroughly. Check the flange for cracks or damage – replace if necessary.

Step 5: Install the New Wax Ring
Place the new wax ring (like the Hibbent Kit) onto the bottom of the toilet or directly onto the flange. Make sure it’s centered and secure.

Step 6: Set the New Toilet
Carefully lower the toilet onto the flange, aligning the holes with the bolts. Press down firmly to compress the wax ring and create a watertight seal.

Step 7: Secure the Toilet
Add washers and nuts to the closet bolts and tighten evenly. Don’t overtighten – this can crack the porcelain. Snap on the bolt caps for a clean finish.

Step 8: Reconnect the Water Line
Attach the new supply line (like the Highcraft Connector) to the shut-off valve and the toilet tank. Tighten with your wrench.

Step 9: Turn On Water & Test
Turn the shut-off valve counterclockwise to restore water. Let the tank fill, then flush and check for leaks around the base and connections.

Common Mistakes to Avoid

  • Reusing the old wax ring – Always use a fresh one for a proper seal.
  • Overtightening bolts – Can crack the toilet base.
  • Skipping flange inspection – A damaged flange leads to leaks.
  • Not leveling the toilet – Can cause wobbling and future seal failure.
