Changing a toilet involves a series of steps to safely remove the old one and install a new one. Here's a step-by-step guide:
1. Preparation
- Turn off the water supply: Locate the toilet's water shut-off valve (usually behind the toilet) and turn it clockwise until it's completely closed.
- Flush the toilet: Flush the toilet to remove as much water as possible from the bowl and tank.
- Remove remaining water: Use a sponge or small container to remove any remaining water in the tank and bowl.
2. Disconnecting the Old Toilet
- Disconnect the water supply line: Use a wrench to disconnect the water supply tube from the toilet tank. Have a bucket ready to catch any residual water.
- Remove the toilet seat: Unscrew the bolts holding the toilet seat to the toilet.
- Remove the bolt caps: If present, remove the plastic caps covering the bolts at the base of the toilet.
- Remove the mounting nuts: Using a wrench, carefully loosen and remove the nuts securing the toilet to the floor. These may be corroded, so be patient.
- Break the seal (if necessary): If the toilet is stuck, gently rock it from side to side to break the wax ring seal.
3. Removing the Old Toilet
- Lift and remove the toilet: Carefully lift the toilet straight up and off the flange. It might be heavy, so consider having someone help you.
- Place the toilet on a protected surface: Set the old toilet on its side on cardboard or an old blanket to avoid damaging the floor or the toilet itself.
4. Preparing for the New Toilet
- Scrape away old wax ring: Use a putty knife or scraper to remove the old wax ring from the flange and the bottom of the old toilet (if any residue is stuck there).
- Inspect the flange: Check the flange (the metal or plastic ring bolted to the floor) for damage. If it's cracked or corroded, you'll need to repair or replace it.
- Install new closet bolts: Insert new closet bolts into the flange slots. These bolts will secure the new toilet.
5. Installing the New Toilet
- Install the new wax ring: Center a new wax ring on the flange, pressing it firmly into place. Alternatively, some wax rings can be attached to the bottom of the toilet. Follow the manufacturer's instructions.
- Position the toilet: Carefully align the toilet over the closet bolts and lower it straight down onto the flange.
- Apply gentle pressure: Gently rock the toilet to ensure the wax ring creates a good seal.
- Install washers and nuts: Place the washers and nuts onto the closet bolts and hand-tighten them.
- Tighten the nuts: Using a wrench, gradually tighten the nuts alternately, a little at a time, to ensure even pressure. Do not overtighten, as this can crack the porcelain.
- Install bolt caps: Snap the bolt caps over the bolts (if applicable).
- Connect the water supply line: Attach the water supply tube to the toilet tank and tighten the connection.
- Turn on the water supply: Slowly turn the water shut-off valve counterclockwise to turn the water back on.
- Check for leaks: Check all connections for leaks. Tighten connections if needed.
- Install the toilet seat: Attach the new toilet seat using the provided hardware.
6. Final Steps
- Flush the toilet: Flush the toilet several times to ensure it's working properly and there are no leaks.
- Caulk (optional): Apply a bead of caulk around the base of the toilet where it meets the floor. This helps prevent leaks and keeps the toilet secure.
Important Considerations:
- Always consult the manufacturer's instructions for your specific toilet model.
- If you're not comfortable performing any of these steps, it's best to hire a qualified plumber.
- Dispose of the old toilet properly. Contact your local waste management company for disposal options.
