In this comprehensive guide, we’ll walk you through the step-by-step process of replacing tub faucet knobs, empowering you with the skills to tackle this task with confidence.

Tools and Materials You’ll Need

• Adjustable wrench
• Allen key (if required)
• Screwdriver
• Replacement faucet knobs

Safety First: Shut Off the Water Supply

Before you begin, it’s crucial to shut off the water supply to your tub. Locate the shut-off valves beneath the sink or behind the tub and turn them clockwise to close them.

Removing the Old Faucet Knobs

1. Identify the Type of Knob

There are two main types of faucet knobs: screw-on and lever. Screw-on knobs are attached with screws, while lever knobs are secured with an Allen key.

2. Remove the Screw-On Knobs

Using an adjustable wrench, gently loosen the set screw on the base of the knob. Once the screw is loose, pull the knob straight off the faucet stem.

3. Remove the Lever Knobs

Insert the Allen key into the small hole on the base of the lever knob. Turn the key counterclockwise to loosen the knob and slide it off the stem.

Installing the New Faucet Knobs

1. Align the New Knobs

Align the splines on the new faucet knobs with the splines on the faucet stems. Ensure that the knobs are facing the correct direction.

2. Tighten the Screw-On Knobs

Place the new screw-on knobs over the stems and tighten them with an adjustable wrench. Avoid overtightening to prevent damage.

3. Tighten the Lever Knobs

Insert the lever knobs onto the stems and tighten them using the Allen key. Turn the key clockwise until the knobs are securely in place.

Reopening the Water Supply

Once the new faucet knobs are installed, slowly reopen the water supply valves. Check for any leaks around the knobs. If there are any leaks, tighten the knobs further.

Troubleshooting Common Issues

1. Leaking Knobs

If the knobs leak after installation, it could be due to loose packing nuts. Tighten the packing nuts with an adjustable wrench until the leak stops.

2. Stiff Knobs

If the knobs are stiff to turn, it could be due to mineral buildup or corrosion. Apply a lubricant, such as WD-40, to the knob stems and work the knobs back and forth to loosen them up.

Tips for Long-Lasting Faucet Knobs

• Clean the faucet knobs regularly with a mild detergent and water.
• Avoid using abrasive cleaners or harsh chemicals.
• If the knobs become loose over time, tighten them with an adjustable wrench.
• Replace the faucet knobs every 5-10 years to prevent leaks and ensure smooth operation.

Information You Need to Know

1. Can I replace faucet knobs without turning off the water supply?

No, it’s not recommended to replace faucet knobs without turning off the water supply. Water under pressure can spray out when the knobs are removed, causing a mess and potential injury.

2. How often should I replace faucet knobs?

Faucet knobs typically last for 5-10 years. However, if they become loose, leaky, or difficult to turn, it’s best to replace them sooner.

3. What type of lubricant should I use on faucet knobs?

Use a lubricant specifically designed for plumbing, such as silicone grease or WD-40. Avoid using petroleum-based lubricants, as they can damage the rubber seals.
