Replacing a bathroom sink faucet is a relatively simple task that can be completed in under an hour. However, before you begin, it is important to gather all of the necessary tools and materials. You will need a new faucet, a wrench, a screwdriver, and a bucket. Once you have gathered your materials, you can follow these steps to replace your bathroom sink faucet.
First, turn off the water supply to your sink. To do this, locate the shut-off valves beneath your sink and turn them clockwise. Once the water supply is turned off, you can proceed to disconnect the old faucet. Use a wrench to loosen the nuts that are holding the faucet in place. Once the nuts are loose, you can gently pull the faucet out of the sink.
Next, you can install the new faucet. To do this, first insert the new faucet into the sinkhole. Then, use a wrench to tighten the nuts that are holding the faucet in place. Be sure to tighten the nuts securely, but do not overtighten them. Finally, turn on the water supply to your sink and check for any leaks. If you find any leaks, tighten the nuts until the leak stops.
Preparing for the Replacement
Before you begin replacing your bathroom sink faucet, there are a few important steps you need to take to ensure a smooth and successful installation.
Gathering Materials
First and foremost, gather all the necessary materials you’ll need for the replacement. This includes the new faucet, a wrench (preferably an adjustable wrench), a basin wrench, a plumber’s putty, and a few rags. If your new faucet comes with any special tools or fittings, make sure to have those on hand as well.
Turning Off the Water Supply
Next, you’ll need to turn off the water supply to your sink. Locate the shut-off valves beneath the sink and turn them clockwise until the water flow stops completely. If there are no shut-off valves installed, you may need to turn off the main water supply to your home.
Draining the Faucet
Once the water supply is turned off, open the faucet to allow any remaining water to drain out of the pipes and faucet body. Use a rag to absorb any spills and keep the work area dry.
Disconnecting the Old Faucet
Now, it’s time to disconnect the old faucet. Use the basin wrench to loosen the nuts that connect the faucet to the sink. If these nuts are too tight or rusted, you can use an adjustable wrench for additional leverage. Be careful not to overtighten or strip the nuts.
Once the nuts are loosened, you should be able to gently pull the faucet out of the sink. There may still be some remaining water in the faucet, so tilt it slightly to drain it out before placing it aside.
| Shut-Off Valve Location | Typical Type of Valve |
|---|---|
| Beneath the sink | Gate valve or ball valve |
| Behind the access panel | Gate valve or quarter-turn valve |
| Water heater closet | Ball valve or lever valve |
Connecting the Water Supply
Once the old faucet is removed, it’s time to connect the water supply to the new faucet. Here’s a more detailed step-by-step guide:
1. Gather Necessary Materials
Before you start, make sure you have the following materials on hand:
- 2 adjustable wrenches
- Teflon tape
- Plumber’s putty
- Basin wrench
2. Shut Off the Water Supply
Locate the shut-off valves under the sink and turn them clockwise to shut off the water supply.
3. Disconnect the Old Supply Lines
Use an adjustable wrench to loosen the nuts that connect the supply lines to the old faucet. Be careful not to overtighten.
4. Clean the Connection Points
Use a cloth to wipe away any debris or gunk from the connection points on the water supply valves and the new faucet.
5. Wrap Teflon Tape on the Threads
Apply several layers of Teflon tape clockwise around the threads of the supply lines and the new faucet’s inlet ports.
6. Connect the New Supply Lines
Hand-tighten the new supply lines onto the water supply valves first. Then, use an adjustable wrench to tighten them further, about 1/4 to 1/2 turn past hand-tight.
7. Seal the Drain Hole
Apply a bead of plumber’s putty around the drain hole in the sink. Press the new faucet into the hole and tighten the mounting nut underneath the sink by hand. Use a basin wrench to fully tighten the nut, about 1/4 to 1/2 turn past hand-tight.
8. Check for Leaks
Turn the water supply back on and check for any leaks at the connections. If there are leaks, tighten the connections further.
Testing for Leaks
Once the faucet is installed, it’s crucial to test for any leaks. Here’s how to do it:
1. Open the faucet completely: Allow hot and cold water to flow fully for several minutes.
2. Check the base: Inspect the base of the faucet, where it meets the sink, for any signs of dripping or water accumulation.
3. Check the handles: Move the faucet handles through their full range of motion, checking for any leaks around the base or connection points.
4. Check the connections: With a flashlight, examine the supply lines and drainpipe connections beneath the sink. Look for any moisture or drips.
5. Check the tailpiece: The “tailpiece” is the piece that connects the drainpipe to the sink. Inspect it for any leaks or loose connections.
6. Check the overflow: The “overflow” is the small hole near the top of the sink. Run water until it reaches the overflow level. Check if there are any leaks around the overflow hole.
7. Wait and recheck: After running the faucet for several minutes, close it and wait for a few hours. Return to the sink and check for any new leaks or water accumulation.
8. Use a flashlight for thorough inspection: Use a flashlight to illuminate any areas that may be difficult to see. This will help you detect even the smallest leaks.
| Leaks | Possible Causes |
|---|---|
| Base of faucet | Loose washer or O-ring, damaged cartridge |
| Handles | Loose handle screw, worn-out O-rings |
| Connections | Loose or improperly tightened connections |
| Tailpiece | Loose washer or damaged tailpiece |
| Overflow | Clogged overflow hole, loose overflow cover |
