Few things in life are more annoying than the incessant drip, drip, drip of a leaky shower head. For some reason, the human brain cannot tune out the sound—the more you try, the louder it seems to get. And beyond the irritation it causes, a leaky shower can also be expensive over time, especially if the drip is from the hot water valve.
Shower Head Leaking? Think Again
While it may seem like your dripping shower head is the root of the problem, it’s not. A leaky shower is usually due to an issue with the faucet valve stem and/or valve cartridge. Your shower head is likely fine.
Replacing a faucet valve stem and/or valve cartridge can be difficult. Below we have included step-by-step instructions for attempting the job on your own. If the project seems too difficult, it’s always smart to contact a professional plumber who knows exactly what needs to be done and how to do it correctly.
- Before you begin, shut off the water supply to the shower. There may be a shut-off valve in the bathroom, or you may need to shut off the main water for the whole house.
- Keep in mind that there will likely be some water remaining in the shower lines, so be prepared for a slight downpour when you begin.
- Place a towel over the bottom of the tub/shower, covering the drain. This will protect the surface from damage if you drop a tool and will keep small parts out of the drain.
How to Fix an In-Wall Faucet Valve
Here’s how to fix a dripping shower head by repairing the in-wall faucet valves in ten steps:
- Turn off the water supply to the tub/shower, and cover the drain with a towel.
- If you have a two-valve system, determine which side is causing the shower leak. If the stem is warm and/or the drip is hot, it is likely the hot side.
- Remove the handle or knob. Then remove the faceplates and sleeves that cover the valve and valve body. Set these aside.
- Now that you can see the valve and valve body, unscrew the valve stem and/or cartridge from the valve body with an adjustable wrench. In some cases, you may need to use a cartridge tool specifically designed for your faucet brand.
- Take the valve stem and/or cartridge to a hardware store to purchase the appropriate replacement parts.
- All washers and/or O-rings, as well as the valve seat, should be replaced as well. These items are typically included in the purchase of new valve stems or cartridges, but check to be sure.
- Before putting everything back together, use a vinegar-and-water solution (equal parts) and an old toothbrush to remove mineral deposits from the area.
- Install the new valve stem and/or cartridge into the valve body according to manufacturer instructions.
- Re-install the sleeve, baseplate, and handle.
- Turn the water supply back on and run the shower for 30 seconds. Turn off and observe to see if there is still a shower leak. If no drip occurs, use caulk around the entire baseplate to seal it to the wall.
