Materials You’ll Need
Before you begin, gather the following materials:
- New toilet water supply line (flexible or braided)
- Adjustable wrench
- Pliers
- Plumber’s tape
- Rags or towels
Safety Precautions
- Turn off the water supply to the toilet by closing the shut-off valve behind it.
- Flush the toilet to drain the tank and bowl.
Step 1: Detach the Old Supply Line
- Using an adjustable wrench, loosen the nuts connecting the old supply line to the toilet fill valve and the shut-off valve.
- Disconnect the supply line by hand or with pliers.
Step 2: Apply Plumber’s Tape
- Wrap several turns of plumber’s tape clockwise around the threads of the new supply line. This will help create a watertight seal.
Step 3: Connect to the Toilet Fill Valve
- Insert the new supply line into the fill valve and hand-tighten the nut.
- Use an adjustable wrench to further tighten the nut, but avoid overtightening.
Step 4: Connect to the Shut-Off Valve
- Insert the other end of the supply line into the shut-off valve and hand-tighten the nut.
- Use an adjustable wrench to tighten the nut securely.
Step 5: Turn on the Water Supply
- Slowly turn on the shut-off valve to allow water to flow through the supply line.
- Check for any leaks at the connections. If you notice any, tighten the nuts further.
Step 6: Adjust the Length
- If necessary, adjust the length of the supply line by bending it slightly. Avoid kinking or crimping the line.
Step 7: Final Inspection
- Flush the toilet to fill the tank and bowl.
- Inspect the entire supply line for any leaks. If you find any, repeat the previous steps to ensure a proper seal.
Troubleshooting Common Issues
- Leaking at the Fill Valve: Tighten the nut connecting the supply line to the fill valve.
- Leaking at the Shut-Off Valve: Tighten the nut connecting the supply line to the shut-off valve.
