How to Fix a Shower Faucet That Won’t Turn Off: Simple Solutions

If you’re trying to fix a shower faucet that won’t turn off, you’re not alone—it’s a common issue that can be both frustrating and wasteful. The problem can often be solved with a few simple steps! Common causes include a worn-out valve cartridge, a loose handle, or mineral build-up. Start by turning off the water supply, inspecting the handle, and checking the valve cartridge. If necessary, clean or replace corroded parts.

If these fixes don’t solve the issue, or you need a more reliable solution, consider upgrading to a durable, high-quality faucet.

Understanding the cause of your leaky, stuck, or non-turning faucet can go a long way toward solving the issue quickly. Here are some of the most common reasons your shower faucet might not turn off:

Worn Out Valve Cartridge:
The valve cartridge is one of the most common culprits behind a faucet that won’t turn off. Over time, constant use can wear down the cartridge, preventing it from fully shutting off the water.

Loose or Broken Handle:
Sometimes, it’s not the faucet itself but the handle that’s the issue. If the handle is loose, broken, or stripped, it can become difficult—or impossible—to fully shut off the water.

Faulty Diverter Valve:
If you have a tub-and-shower combo, the diverter valve might be the issue. It’s responsible for directing water to the showerhead or bathtub, and if it malfunctions, it can result in water continuing to flow even after the faucet is turned off.

Mineral Build-Up:
Hard water can leave mineral deposits in the faucet and its components, causing them to malfunction. These deposits can block the flow of water or make it difficult to turn off the faucet completely.

Corroded Parts:
If your faucet has been around for a while, corrosion may have set in. Rust and other forms of corrosion can prevent the faucet from working properly, leading to stuck handles or valves that won’t shut off completely.

Now that you know some common reasons your shower faucet may not be turning off, let’s talk about how to fix it.

Before you start any repairs, make sure to turn off the water supply to your shower. This step is essential to avoid making a mess and potentially flooding your bathroom. Look for the main water valve in your home, typically located near the water meter or in your basement. Turn it off before you start working on the faucet.

Check the shower handle. If it’s loose, broken, or stripped, this could be the reason your faucet isn’t turning off. Tighten any loose screws and check the mechanism behind the handle for any damage.

• Tip:If the handle is broken, you may need to replace it entirely. Most hardware stores carry replacement shower handles that can be easily swapped out.

If tightening the handle doesn’t solve the problem, the issue may lie within the valve cartridge. A worn-out or broken cartridge is one of the most common reasons for a faucet that won’t turn off.

• To replace the valve cartridge:
  • Remove the handle by unscrewing any visible screws.
  • Use a wrench or pliers to pull out the old valve cartridge. Be gentle so as not to damage surrounding components.
  • Insert the new cartridge, ensuring it’s properly aligned.
  • Reassemble the handle and test the faucet.

If you’re not comfortable doing this yourself, consider calling a plumber, as this task can be tricky if you’re unfamiliar with plumbing parts.

For tub-and-shower combinations, a faulty diverter valve could be the problem. To check it, try operating the diverter and listen for any unusual sounds. If the diverter won’t properly switch between the tub and shower, it may be stuck or damaged.

• Fixing a diverter valve:
  • Try soaking the valve in vinegar to dissolve any mineral build-up.
  • If it’s still not working, you may need to replace the diverter valve.

If your shower faucet is old or you have hard water, mineral deposits might have built up inside the faucet’s components, preventing it from shutting off correctly. A good cleaning can often do the trick.

• How to clean:
  • Soak the faucet parts (such as the valve cartridge) in white vinegar for a few hours to dissolve the mineral build-up.
  • Scrub any visible mineral deposits with a soft brush.
  • Reassemble and check if the issue is resolved.

If corrosion is the issue, the affected parts will need to be replaced. This may require replacing the faucet itself, or at least the components that have rusted or corroded beyond repair. In this case, it’s often a good idea to replace the entire faucet for long-term reliability.
