How to Fix a Leaky Showerhead: A Comprehensive Guide
A leaky showerhead can be a major annoyance, not to mention a waste of water. If you’re experiencing this problem, don’t worry – you can fix it yourself in most cases without the need for a plumber. In this article, we’ll provide a step-by-step guide to repairing a showerhead and replacing a leaky shower cartridge.
Identifying the Source of the Leak
The first step in fixing a leaky showerhead is to identify the source of the leak. There are two main possibilities:
- Faucet ON: If the showerhead leaks when the faucet is turned on, the problem is likely with the showerhead itself. Sediment buildup or a damaged O-ring can cause water to leak from the showerhead holes.
- Faucet OFF: If the showerhead leaks when the faucet is turned off, the problem is likely with the shower cartridge. The cartridge is a replaceable component inside the faucet body that controls the flow of water. A worn or damaged cartridge can allow water to leak past even when the faucet is closed.
Repairing a Leaky Showerhead
If the source of the leak is the showerhead itself, you can try the following steps:
- Remove the Showerhead: Turn the shower faucet handle to the OFF position and unscrew the showerhead by hand. If the showerhead is difficult to turn, you can use a damp washcloth to grip it or channel-lock pliers.
- Inspect and Clean the Showerhead: Check the inside of the showerhead for any damaged or blocked parts, such as rubber O-rings or a clogged screen. If the showerhead is dirty, submerge it in a bowl of white vinegar for an hour or two and then rinse it off with cold water.
- Wrap Pipe Threads: Clean the threads of the shower arm with a small nylon scrub brush and wrap them with one or two loops of thread-sealing tape. Wrap the tape clockwise.
- Reassemble the Showerhead: Thread the showerhead back onto the shower arm and tighten it by hand. Turn on the shower faucet briefly to check for leaks. If the showerhead continues to leak, you may need to replace it.
Replacing a Leaky Shower Cartridge
If the source of the leak is the shower cartridge, you will need to replace it. Here’s how:
- Shut Off the Water: Turn off the water supply to the shower. This may require turning off the main water shutoff valve if your shower does not have fixture shutoff valves.
- Remove the Faucet Handle: Remove the cap at the end of the shower faucet handle and unscrew the handle screw. You may need to use a hex wrench to remove the handle screw.
- Remove the Escutcheon Plate: Remove the faceplate or escutcheon that covers the faucet valve. You may need to cut through a caulk bead around the escutcheon.
- Remove the Retaining Clip: Pry off the metal retaining clip that holds the cartridge in place. If there are washers present on the end of the cartridge, remove them.
- Slide Out the Cartridge: Slide the existing cartridge out from the faucet body. In most cases, the cartridge will slide straight out, but you may need to use channel-lock pliers to grip the stem and turn the cartridge to remove it.
- Install a New Cartridge: Slide the new shower cartridge into the faucet body, aligning the tab on the cartridge with the groove on the faucet body. Replace the retaining clip and any washers you removed.
- Replace the Escutcheon and Handle: Reattach the escutcheon plate and the faucet handle. Turn on the water supply and test the shower to ensure that the new cartridge is working properly.
Troubleshooting Common Showerhead Leaks
If you have tried the steps above and the showerhead is still leaking, there may be a more serious underlying problem. In this case, it is best to call a licensed plumber for assistance.
