Connecting a toilet water supply is a crucial plumbing task that ensures a functional and hygienic bathroom. Whether you’re replacing an old toilet or installing a new one, this step-by-step guide will empower you with the knowledge and confidence to complete the job like a pro. In this comprehensive walkthrough, we’ll cover everything you need to know, from gathering the necessary materials to making the final connections.
Materials You’ll Need
- Toilet
- Toilet flange
- Toilet wax ring
- Flexible supply line
- Adjustable wrench
- Plumber’s putty
- Hacksaw or pipe cutter
- Measuring tape
Step 1: Remove the Old Toilet (if necessary)
If you’re replacing an existing toilet, start by turning off the water supply and flushing the toilet to empty the tank. Disconnect the supply line, unbolt the toilet from the floor, and lift it off the flange. Remove the old wax ring and clean the flange thoroughly.
Step 2: Install the Toilet Flange
If there’s no existing flange, you’ll need to install one. Measure the distance from the wall to the center of the drain pipe and mark the floor accordingly. Place the flange over the drain pipe and secure it with screws.
Step 3: Apply Plumber’s Putty to the Flange
Roll out a rope of plumber’s putty and apply it around the bottom of the flange. This will create a watertight seal between the flange and the toilet.
Step 4: Set the Toilet on the Flange
Carefully lift the toilet and set it on the flange. Align the bolts with the holes in the toilet base and hand-tighten the nuts.
Step 5: Cut and Connect the Supply Line
Measure the distance from the toilet’s fill valve to the water supply shut-off valve. Cut the supply line to the desired length using a hacksaw or pipe cutter. Attach one end of the supply line to the fill valve and the other end to the shut-off valve.
Step 6: Tighten the Connections
Use an adjustable wrench to tighten the nuts on the toilet bolts and the supply line connections. Avoid overtightening, as this can damage the bolts or supply line.
Step 7: Test the Toilet
Turn on the water supply and flush the toilet. Check for any leaks around the flange, bolts, or supply line connections. If you notice any leaks, tighten the connections further or apply additional plumber‘s putty.
Troubleshooting Tips
- Toilet won’t stop running: Check the fill valve and float mechanism for any debris or damage. Adjust the float or replace the fill valve if necessary.
- Toilet is leaking from the base: Remove the toilet and check the wax ring for damage. Replace the wax ring and reinstall the toilet.
- Toilet is rocking or wobbly: Tighten the bolts connecting the toilet to the flange. If the flange is loose, secure it with additional screws.
