A leaky or non-functioning tub shower diverter can be a major inconvenience. Not only can it lead to wasted water, but it can also make it difficult to take a comfortable shower. The good news is that in many cases, it is possible to fix a tub shower diverter without having to call a plumber. Here are a few simple steps to help you get started.

First, you need to identify the type of diverter you have. There are two main types of tub shower diverters: manual and pressure-balance. Manual diverters are operated by a lever or knob, while pressure-balance diverters use water pressure to automatically adjust the flow of water. Once you have identified the type of diverter you have, you can begin the repair process. For manual diverters, you may simply need to tighten the packing nut or replace the washer. For pressure-balance diverters, you may need to adjust the diaphragm or replace the cartridge. Regardless of the type of diverter you have, it is important to follow the manufacturer’s instructions carefully.

If you are unable to fix the tub shower diverter yourself, it is important to call a qualified plumber. A plumber will be able to diagnose the problem and make the necessary repairs quickly and efficiently. However, by following the steps outlined above, you may be able to save yourself the cost of a plumber and get your tub shower diverter working properly again in no time.

Identifying the Type of Diverter

The first step in fixing a tub shower diverter is to identify the type of diverter you have. There are several different types of diverters, each with its own unique design and repair procedures.

### Tub Spout Diverter
A tub spout diverter is located at the end of the tub spout. It is a small, round or square knob that you turn to divert the water from the spout to the showerhead. This type of diverter is the easiest to repair, as it is easy to access and does not require any special tools.

### Wall-Mounted Diverter
A wall-mounted diverter is located on the wall of the shower enclosure. It is a larger, square or rectangular plate that has a lever or knob that you use to divert the water from the tub spout to the showerhead. This type of diverter is more difficult to repair than a tub spout diverter, as it requires removing the faceplate and accessing the internal components.

### In-Line Diverter
An in-line diverter is located inside the wall, between the tub spout and the showerhead. It is a small, cylindrical device that has a lever or knob that you use to divert the water from the tub spout to the showerhead. This type of diverter is the most difficult to repair, as it requires cutting into the wall to access it.

Once you have identified the type of diverter you have, you can begin the repair process.

| Tub Spout Diverter | Wall-Mounted Diverter | In-Line Diverter |
|:—|:—|:—|
| Located at the end of the tub spout | Located on the wall of the shower enclosure | Located inside the wall, between the tub spout and the showerhead |
| Small, round or square knob | Larger, square or rectangular plate | Small, cylindrical device |
| Easiest to repair | More difficult to repair | Most difficult to repair |

Checking for Blockages

The next step in troubleshooting a stuck tub shower diverter is to check for blockages. These blockages can prevent the diverter from moving freely, causing it to become stuck.
There are several potential sources of blockages in a tub shower diverter, including:

  • Mineral deposits: Hard water can cause mineral deposits to build up on the diverter, preventing it from moving.
  • Corrosion: Over time, the diverter can corrode, making it difficult to move.
  • Dirt and debris: Dirt and debris can get into the diverter and prevent it from moving.

Types of blockage

Signs and symptoms

Potential solutions

Mineral deposits

White or brown crusty build-up on the diverter

Use a vinegar or CLR solution to dissolve the deposits

Corrosion

Rust or other discoloration on the diverter

Replace the diverter

Dirt and debris

Visible dirt or debris on the diverter

Use a toothbrush or other small brush to clean the diverter

To check for blockages, remove the diverter and inspect it for any of the signs listed above. If you find any blockages, clean them away using the appropriate method. Once the blockages are removed, reattach the diverter and test it to see if it is now working properly.

How to Replace a Worn-Out Washer

A worn-out washer in your tub shower diverter can cause leaks or difficulty switching between the tub and shower. Replacing the washer is a relatively simple task that can be completed in a few steps.

Materials Needed:

Item Quantity
Replacement washer 1
Phillips screwdriver 1
Flathead screwdriver 1

Instructions:

  1. Turn off the water supply. Locate the shut-off valves for the hot and cold water lines and turn them off clockwise.
  2. Remove the old washer. Use a flathead screwdriver to pry off the old washer from the base of the diverter. Be careful not to damage the base.
  3. Inspect the diverter base. Check the diverter base for any signs of damage or wear. If the base is damaged, it may need to be replaced.
  4. Clean the diverter base. Use a soft cloth to clean the diverter base and remove any debris or dirt.
  5. Install the new washer. Place the new washer over the diverter base and press it into place using your fingers.
  6. Reassemble the diverter. Replace the diverter handle and screw it back into place using a Phillips screwdriver.
  7. Turn on the water supply. Turn on the shut-off valves to allow water to flow through the diverter. Check for any leaks.

Step-by-Step Guide to Removing the Diverter Handle

4. Removing the Escutcheon and Cartridge

Now that the handle is removed, you’ll need to remove the escutcheon, which is the decorative plate around the handle. It’s usually held in place by a few screws or a snap-on mechanism. Once the escutcheon is removed, you’ll see the cartridge, which is the main component of the diverter.

To remove the cartridge, follow these steps:

Step Description
1 Identify the type of cartridge you have. There are two main types: stem-type and ball-type.
2 For stem-type cartridges, grasp the handle (if still attached) and pull it straight out.
3 For ball-type cartridges, there will be a screw or cap on the top of the cartridge. Remove the screw or cap, then pull the cartridge straight out.
4 Once the cartridge is removed, you can clean it or replace it with a new one.

How to Disassemble the Diverter Cartridge

Disassembling the diverter cartridge involves the following steps:

  1. Locate the diverter cartridge. This is typically found behind the handle or faceplate of the shower diverter. Refer to the manufacturer’s instructions for specific location.
  2. Remove the handle or faceplate. This may require unscrewing screws or removing a retainer clip.
  3. Unscrew the diverter cartridge. Use a wrench or pliers to loosen and remove the cartridge.
  4. Inspect the cartridge for damage. Look for any cracks, leaks, or obstructions that may be causing the diverter to malfunction.
  5. Clean the cartridge and surrounding area. Use a cloth dampened with a mild cleaner or lubricant to wipe away any dirt or debris that may have accumulated.

Detailed Instructions for Cleaning the Cartridge and Surrounding Area

Step Description
5a Prepare a cleaning solution. Mix a mild cleaning agent (e.g., dish soap) with warm water in a small bowl or container.
5b Apply the solution. Dip a soft cloth into the cleaning solution and gently wipe the cartridge and surrounding area. Avoid using harsh chemicals or abrasive cleaners that may damage the components.
5c Remove dirt and debris. Use a toothbrush or soft brush to gently remove any stubborn dirt or debris that may have accumulated in crevices or around the cartridge.
