Safety Precautions

Before commencing any plumbing work, ensure your safety by following these precautions:

Step-by-Step Instructions

1. Locate the Water Supply Line

• Inspect the base of the toilet to identify the water supply line. It’s typically a flexible hose connected to the bottom of the toilet tank.

2. Disconnect the Water Supply Line

• Using an adjustable wrench, carefully loosen the nut connecting the water supply line to the toilet tank.
• If the connection is inaccessible, use a basin wrench to reach around and loosen the nut.
• Hold a rag or towel beneath the connection to catch any dripping water.

3. Remove the Water Supply Line

• Gently pull the water supply line away from the toilet tank.
• If it’s stuck, gently wiggle it back and forth until it comes loose.

4. Inspect the Water Supply Line

• Check the water supply line for any damage or leaks.
• If it’s damaged, replace it with a new one of the same size and type.

5. Install a New Water Supply Line (Optional)

• If you’re replacing the water supply line, insert the new line into the toilet tank and hand-tighten the nut.
• Use an adjustable wrench to further tighten the nut, but avoid overtightening.

6. Reconnect the Water Supply Line

• Align the water supply line with the connection on the toilet tank.
• Hand-tighten the nut, then use an adjustable wrench to further tighten it.
• Ensure the connection is secure but not overly tight.

7. Turn on the Water Supply

• Slowly turn on the water supply at the main shut-off valve.
• Check for any leaks at the connection.
• If there are leaks, tighten the nut further or replace the water supply line.

Finishing Touches

• Flush the toilet several times to fill the tank and check for proper operation.
• Remove any rags or towels used during the process.
• Clean up any spills or water droplets.
