How to Adjust a Diverter: A Step-by-Step Guide

 A diverter controls the flow of water between the tub spout and the showerhead, allowing you to switch between them. Over time, the diverter can become misaligned or need adjustment to function properly. Here’s a step-by-step guide to help you adjust a diverter effectively.

Tools and Materials Needed

• Adjustable Wrench or Pliers
• Screwdriver (Flathead or Phillips)
• Lubricant (Silicone-based or penetrating oil, optional)
• Clean Cloth or Towel

1. Identify the Type of Diverter

Before making adjustments, determine the type of diverter you have. The common types are:

• Lever-Type Diverter: A lever on the faucet handle that you push or pull to switch between tub and shower.
• Rotary Diverter: A dial or knob that you turn to select the water flow.
• Tub Spout Diverter: A small lever or knob built into the tub spout itself.

2. Turn Off the Water Supply

1. Locate the Shutoff Valves: Find the individual shutoff valves for the tub or the main water shutoff valve for your home.
2. Turn Off the Valves: Turn them clockwise to stop the water supply.
3. Drain the Pipes: Open the faucet to let any remaining water out.

3. Disassemble the Diverter

1. Remove the Handle:

   • Locate the Screw: Find the screw holding the diverter handle. It might be under a decorative cap or behind a cover plate.
   • Unscrew the Handle: Use a screwdriver to remove the handle. Keep the screw and any removed parts for reassembly.

2. Inspect the Diverter:

   • Look for Obstructions: Check for any debris, rust, or corrosion that might be affecting the diverter’s operation.
   • Clean the Area: Wipe away any dirt or buildup with a clean cloth.

4. Adjust the Diverter

1. Check for Proper Alignment:

   • Lever-Type Diverter: Ensure the lever moves smoothly and fully engages both the tub and shower settings. If it’s not aligning correctly, adjust its position or replace it if it’s worn out.
   • Rotary Diverter: Confirm that the dial or knob turns freely and aligns properly with the settings. Adjust the position or replace the diverter if it’s not functioning correctly.
   • Tub Spout Diverter: Ensure that the lever or knob on the spout moves smoothly and correctly directs water. Adjust or replace if it’s sticking or not engaging fully.

2. Lubricate the Diverter (If Needed):

   • Apply Lubricant: Use a silicone-based lubricant or penetrating oil to the moving parts of the diverter. This can help if the diverter is stiff or difficult to operate.
   • Move the Diverter: Operate the diverter to distribute the lubricant evenly.

5. Reassemble and Test

1. Reattach the Handle:

   • Secure the Handle: Put the handle back on and screw it into place. Replace any decorative caps or cover plates.

2. Turn On the Water Supply:

   • Reopen the Valves: Turn the shutoff valves counterclockwise to restore the water supply.
   • Test the Diverter: Move the diverter to check if it switches smoothly and directs water correctly between the tub spout and showerhead.

3. Check for Leaks:

   • Inspect the area around the diverter for any signs of leaks. Ensure that water flows properly to the selected outlet.

6. Address Persistent Issues

1. Replace Worn Parts:

   • If the diverter still doesn’t work properly after adjustment, you may need to replace worn or damaged parts.

2. Consult a Professional:

   • If you’re unable to resolve the issue or if there are signs of significant damage, consider contacting a professional plumber for assistance.

Conclusion

Adjusting a diverter involves inspecting and aligning the mechanism to ensure smooth operation between the tub spout and the showerhead. By following these steps, you can effectively troubleshoot and adjust your diverter. Regular maintenance, including cleaning and lubricating, can help keep your diverter functioning properly.
