Once you've located the screw, use the appropriate screwdriver or Allen wrench to loosen and remove it.
After removing the screw, carefully pull the faucet handle away from the faucet body. Be cautious not to damage any surrounding components or finishes. If the handle feels stuck, try gently wiggling it back and forth while pulling to release any mineral deposits or corrosion that might be holding it in place. In some cases, you may need to use a handle puller tool to safely remove the handle without causing damage. With the handle removed, set it aside in a safe place, taking care not to lose any small parts or screws.
Now that the faucet handle is off, you'll have access to the internal components, including the cartridge, stem, or valve assembly. Take a moment to inspect these components for signs of wear, damage, or mineral buildup. If you notice any issues, such as a cracked cartridge or corroded stem, make a note of the problem and the specific part that needs replacement. It's essential to identify the exact make and model of your faucet to ensure you purchase the correct replacement parts. You can usually find this information on the faucet body or in the manufacturer's documentation.
Before proceeding with any repairs or replacements, use a soft cloth or brush to clean the internal components and surrounding areas. Remove any mineral deposits, debris, or old plumber's tape to ensure a proper seal when reassembling the faucet. If you're planning to replace any parts, have the new components ready and compare them to the old ones to ensure they match. By thoroughly shutting off the water supply and carefully disassembling the faucet handle, you'll be well-prepared to tackle the next steps in fixing your single-faucet shower, whether it's replacing a worn-out cartridge or addressing a more complex issue.

Tighten loose connections or replace damaged O-rings to stop dripping
A common cause of dripping in a single-faucet shower is loose connections or worn-out O-rings within the faucet assembly. O-rings are small, circular seals made of rubber or plastic that prevent water from leaking through gaps in the faucet mechanism. Over time, these O-rings can degrade, harden, or become misaligned, leading to leaks. Similarly, connections between the faucet handle, cartridge, and spout can loosen due to regular use or water pressure, causing water to drip even when the faucet is turned off. Addressing these issues is a straightforward DIY task that can save you from unnecessary water waste and repair costs.
To begin, turn off the water supply to the shower to avoid any accidents or mess. This is typically done by locating the shut-off valves under the sink or in the basement. Once the water is off, remove the faucet handle by unscrewing the screw cover (if present) and lifting the handle off. This exposes the cartridge or stem beneath. Use a wrench or pliers to carefully remove the retaining nut or collar holding the cartridge in place. Inspect the O-rings on the cartridge or stem for signs of damage, such as cracks, brittleness, or distortion. If the O-rings appear worn, they should be replaced with new ones of the same size, which can be found at most hardware stores.
Next, focus on tightening any loose connections. Check the threads on the cartridge, stem, and spout for signs of wear or corrosion. If the threads are in good condition, reattach the components, ensuring they are snug but not overtightened, as this can cause damage. Use thread seal tape or pipe compound on the threads for added security against leaks. Reassemble the faucet by placing the cartridge back into the faucet body, securing it with the retaining nut, and reattaching the handle. Turn the water supply back on and test the faucet to ensure the dripping has stopped.
If the dripping persists, double-check the O-rings and connections for any overlooked issues. Sometimes, multiple O-rings may need replacement, or there could be hidden damage in the faucet assembly. In such cases, consider disassembling the faucet further to inspect the spout or valve seat for damage. If the problem remains unresolved, it may be necessary to consult a professional plumber or replace the entire faucet cartridge or assembly.
Regular maintenance, such as periodically checking for loose connections and replacing O-rings every few years, can prevent dripping and extend the life of your shower faucet. Keeping an eye on early signs of wear, like minor leaks or stiffness in the handle, allows you to address issues before they worsen. By tightening loose connections and replacing damaged O-rings, you can effectively stop dripping and maintain a functional, efficient shower faucet.
