How To Fix A Stripped Shower Knob? [DIY Simple Fix]

Starting your day with the anticipation of a soothing morning shower, only to find your shower knob stripped and water flowing aimlessly, can be truly frustrating.

However, with a bit of DIY knowledge, you can tackle this problem and restore your shower to its former glory. In this comprehensive guide, we will walk you through the step-by-step process of fixing a stripped shower knob.

We’ll also explore quick fixes, temporary solutions, and pro tips to ensure a seamless shower experience.

Understanding the Issue

Is my faucet knob broken? This common question often arises when your shower faucet handles become loose or the showerhead continues to drip after you’ve turned it off. Typically, the culprit is a stripped shower knob, but the real issue lies in the faucet cartridge, which controls water flow. When the cartridge wears out due to age and usage, the handle may feel loose or spin freely. Fortunately, with the right tools and techniques, you can address this problem effectively.

Step 1: Disconnect the Water Supply

Depending on your shower’s configuration, you may find shutoff valves behind it. If present, close both valves and open the faucet to release any remaining pressure. In cases without shutoff valves, use the main water shutoff valve for your house. Opening another faucet at a lower level helps relieve system pressure.

Step 2: Prepare Your Work Area

To prevent losing small parts or screws down the drain, cover the shower floor with a drop cloth when working in the shower or sink area. This precaution ensures that you have all the necessary components during reassembly.

Step 3: Remove the Escutcheon Plate and Shower Knob

In most cases, a screw is hidden behind a cap on the front of a single-handle shower knob. Pry off the cap using a flathead screwdriver and then turn the screw counterclockwise. Depending on the faucet’s brand and model, you may require a hex key or Phillips screwdriver. If the knob is stuck, consider using a faucet handle puller. To access the cartridge, you’ll also need to remove the faceplate or escutcheon plate.

Step 4: Take Out the Cartridge

Within the faucet valve, there’s a replaceable cartridge. Remove the retaining clip at the top of the cartridge using a small screwdriver (keep this clip for reinstallation). Most cartridges can be pulled out by gripping the front with pliers. Some cartridges may require a cartridge pulling wrench, which can vary by manufacturer.

Step 5: Replace the Cartridge with an Identical One

Shower faucets come in various shapes and sizes, and each brand may have unique cartridges that are not interchangeable. To ensure a perfect fit, bring your old cartridge to the hardware store when selecting a replacement.

Step 6: Install the New Cartridge

Insert the new cartridge into the faucet valve body and, if necessary, use the included lubricant. Secure the cartridge in place by attaching the retaining clip.

Step 7: Reassemble the Faucet

Reinstall the escutcheon plate if it was removed. Reattach the handle and secure it with the screw. Add the cap back onto the knob.

Step 8: Restore the Water Supply

After turning the water supply back on, test your newly installed cartridge by running the faucet and checking for leaks.

Quick Fix

If cleaning the cartridge doesn’t work, you may need to replace it. As a quick fix, you can enhance the grip of the handle with thread-seal tape. This temporary solution can buy you some time while you gather the necessary supplies for a permanent repair.

Temporary Solutions

In cases where the cartridge cannot be cleaned or repaired, you may have to replace it. To keep your shower functional while preparing for the repair, follow these steps:

• Ensure the water is turned off.
• Place a rag over the drain to catch any small parts.
• After removing the handle and cover plate, inspect the grooves where the handle attaches to the valve.
• If the grooves are worn but still visible, you can temporarily improve the grip by wrapping thread-seal tape (also known as Teflon tape or plumber’s tape) around the cartridge’s ridged end.
• Screw the knob back into place after applying the plumber’s tape.
• Using this temporary remedy will give you some time to gather your plumbing kit and the supplies you’ll need for a permanent shower faucet repair.

Pro Tips

Cartridge Selection: When choosing a replacement cartridge, make sure it matches the old one. Bringing the old cartridge to the hardware store is a surefire way to find an exact match.

Preventative Maintenance: Consider regular maintenance for your plumbing. Having a plumbing kit on hand is wise, as it can be used for various tasks, such as fixing a water heater drain valve or addressing other plumbing issues around the house.

Professional Assistance: If you’re unsure or the problem persists, it’s wise to contact a professional plumber for assistance. Some shower knobs may be challenging for DIY repair, and if replacement is not an option, a skilled plumber can provide the necessary expertise.
