Down and Dirty Toilet Replacement

Using socket wrench to remove nuts on toilet flange bolts.

Step #3: Disconnect Toilet

The next step is to disconnect the water supply line and remove the bolts holding the toilet to the floor.

How to disconnect a toilet:

  1. Lubricate Toilet Flange Bolts: The toilet flange bolts, which hold the toilet to the floor, often become corroded and frozen over time. Use a flathead screwdriver to remove the caps on the toilet flange bolts. Spray the flange nuts and bolts with penetrating oil and allow the oil to soak in.
  2. Disconnect Water Supply Line: Use an open end or adjustable wrench to unscrew the supply line fitting from the tank by turning the supply line coupling nut counterclockwise. Have a pan or small bucket handy to catch any water in the supply line. If you plan to replace the supply line, use a wrench to disconnect the supply line from the shutoff valve as well.
  3. Remove Toilet Flange Bolts: After the penetrating oil has been given time to work, remove the toilet flange nuts by turning them counterclockwise with a ratcheting socket or closed end wrench.

      Try carefully tightening the toilet bolts that hold the toilet to the floor up, but don’t overdo it as it could crack the porcelain bowl. If that doesn’t help, put a shim between the floor and toilet.
