How To Install A Toilet

Installing a toilet can be a moderately challenging DIY project. Here are step-by-step instructions on how to install a toilet. Please note that this is a general overview, and you should always follow the specific instructions provided with your toilet and consult a professional plumber if you're unsure or uncomfortable with any step.

Tools and Materials You'll Need:

1. New toilet
2. Toilet wax ring with horn
3. Adjustable wrench
4. Screwdriver
5. Level
6. Toilet bolts
7. Plumber's putty (optional)
8. Shims (optional)
9. Caulk (optional)
10. Toilet seat (if not included with the toilet)

Step-by-Step Instructions:

1. Preparation:

   • Turn off the water supply to the existing toilet. The water shut-off valve is usually located on the wall or floor behind the toilet.
   • Flush the toilet to empty the tank and bowl.

2. Remove the Old Toilet:

   • Disconnect the water supply line from the toilet tank.
   • Remove the nuts from the bolts securing the toilet to the floor.
   • Lift the old toilet and carefully set it aside or dispose of it properly.

3. Prepare the Floor Flange:

   • Inspect the floor flange (the pipe fitting in the floor where the toilet bolts go) to ensure it's in good condition.
   • Clean any old wax residue or debris from the flange.

4. Install Wax Ring:

   • Place a new wax ring with a horn over the flange, making sure the horn is facing the toilet bowl.

5. Set the New Toilet:

   • Carefully lower the new toilet bowl onto the wax ring, aligning the bolt holes in the base with the floor flange bolts.
   • Press down gently to compress the wax ring and create a watertight seal.

6. Secure the Toilet:

   • Place metal washers and nuts onto the floor flange bolts.
   • Tighten the nuts evenly, but don't overtighten to avoid cracking the toilet base. Use a wrench for this step.
   • If the toilet wobbles, you can use shims under the base to stabilize it.

7. Attach the Tank:

   • If your toilet has a separate tank, follow the manufacturer's instructions to attach it to the bowl.
   • Connect the water supply line to the fill valve on the bottom of the tank.

8. Turn on the Water:

   • Slowly turn on the water supply valve to fill the tank. Check for any leaks around the base and the water supply connection. Tighten if necessary.

9. Check for Level:

   • Place a level across the bowl and tank to ensure the toilet is level. If it's not level, use shims under the base to level it.

10. Install the Toilet Seat:

    • Follow the manufacturer's instructions to install the toilet seat if it's not already attached.

11. Caulk (Optional):

    • Some people choose to caulk around the base of the toilet for aesthetic reasons, but it's not necessary for the toilet's function.

12. Test the Flush:

    • Flush the toilet to ensure it's working correctly. Check for any leaks during and after flushing.

That's it! If you encounter any issues or are unsure about any step in the process, it's advisable to seek help from a professional plumber to ensure the installation is done correctly and safely.
