How to fix the shower faucet won’t turn off all the way?

Follow the steps below to fix your shower faucet:

Step 1: Turn off the water to the shower

The first thing you should do when troubleshooting your shower is turn off the water to the shower. If you’re having trouble turning off the main water supply, try shutting off the main shutoff valve.

If there is a separate shutoff valve for your shower, make sure it is turned all the way to “off.”

Step 2: Unscrew the handle screw and remove handle

Turn off water to the shower. Remove handle screw at the base of your faucet. Pull out the handle, exposing a large nut that holds it in place. Remove this nut by loosening it with an Allen wrench or socket wrench (depending on your type of faucet).

Step 3: Take out the bonnet nut

Next, you’ll need to remove the bonnet nut. This is a hexagonal shaped nut that holds the valve in place and is typically located under the handle of your shower faucet. The size of this nut varies depending on manufacturer, but it’s typically around 1-inch in diameter with a flat surface on top and may be visible or hidden under plastic or rubber caps. If power tools aren’t your thing, don’t worry! Most can be removed by hand as long as you have a wrench handy—and if not, there are always YouTube tutorials available to help guide you through it step by step (just make sure they’re legitimate!).

Step 4: Remove the valve

Remove the valve with a wrench or pliers and set it aside for now. Make sure there are no leaks when you disconnect these parts. If there are, you may need to tighten down some fittings or repair parts before proceeding with further steps.

When everything’s free from its place, examine both sides of the valve stem by turning it back and forth manually until you can see where any blockages might be located (if any). If nothing looks out-of-place, try turning off all hot water sources including your home’s main supply line before removing any additional hoses connected to other valves within your system (you may need an extra pair of hands for this step).

Step 5: Pull out the seat washer and springs

Remove the seat washer and springs by following these steps:

  • Use a pair of pliers to grab the seat washer and pull it out.
  • Remove the spring from its pin by grabbing each side with your thumb and forefinger, then pulling them straight up.

After removing these parts, you can test for leaks around the faucet using soapy water. If there are any leaks, replace them before reassembling your faucet.

Step 6: Apply plumbers’ grease to new parts before replacing them

For your next step, make sure that you clean and dry the new parts. Apply plumbers’ grease to them before installing them. Be careful not to apply too much grease or else it will leak out of the faucet and get onto your hands or clothing.

Step 7: Build a retainer tool for installing springs and washers

If you don’t have a retainer tool, you can make one out of cardboard. Cut out two squares that can fit around the edges of your spring and washer with 1/8″ to ¼” of extra space. Then fold them in half like an envelope. Place the square over top of the disc for which it’s made and wrap it around; this should be snug but not tight enough to cut into them or damage their surfaces.

Step 8: Install parts in order

To install the parts in order, make sure everything is dry before installing. Then test for leaks by turning on the water slowly and checking for leaks around each component.

Step 9: Test for leaks

Once you’ve turned off the water, open up your faucet and let it run. If the leak is a small one, you may be able to see it right away. If not, don’t worry: there are ways to test for leaks without cutting into your wall.

  • Use a light source (like a flashlight) to shine around under your sink or behind other cabinets and fixtures in your bathroom; this will help you spot areas where there might be moisture build-up. If you notice any dampness, check them out individually by running water over them—if they still appear wet after being flushed with fresh water several times and drying completely before closing again (about 20 minutes), then they’re probably leaking!
  • Another option is to buy an inexpensive ultraviolet penlight from an auto parts store (or even just borrow one from someone who works on cars). They’re great at detecting leaks within seconds because their UV rays will show up any drops of moisture that would otherwise go unnoticed by human eyesight alone—a must-have tool if dealing with moldy toilets or leaky pipes!


Congratulations on fixing your shower faucet! Now that you have the right tools and know what to do, it’s easy to fix this problem. The most common cause of this issue is a broken stem cartridge, which can be fixed with a simple replacement kit. If your shower faucet still won’t turn off all the way after replacing the cartridge and adjusting pressure balance valves or other parts, then it may be time for an experienced plumber like us here at Amazing Plumbing!
