Whether you’re aiming to fix a malfunctioning diverter or upgrade to a more modern design, this article will provide the insight and practical advice to get the job done efficiently and effectively.
Removing the Old Bathtub Faucet Diverter
Before installing a new diverter, it is essential to safely remove the existing one. Begin by turning off the water supply to prevent leaks or water damage during the process. This typically involves shutting off the main water valve or the specific valve feeding the bathtub.
Next, use a cloth to protect the tub’s surface and surrounding fixtures. With an adjustable wrench or pliers, carefully loosen the retaining nut or screws holding the diverter in place. If the diverter is part of the spout, you may need to unscrew the entire spout by turning it counterclockwise. In some cases, the diverter might be located on the tub faucet handle or as a separate valve; identify its mounting type accordingly.
If corrosion or mineral deposits make removal difficult, apply a penetrating lubricant and allow it to sit for several minutes before attempting again. Avoid using excessive force to prevent damage to surrounding plumbing or fixtures.
Installing the New Diverter Valve
Once the old diverter is removed, prepare the area for the new installation. Clean the threads and surrounding surfaces to ensure a tight seal and proper fit. Inspect the new diverter for any manufacturer instructions or included parts such as washers or O-rings, which help prevent leaks.
Follow these steps for installation:
- Align the new diverter with the existing plumbing connections.
- Apply plumber’s tape (Teflon tape) to threaded connections to improve sealing.
- Screw or secure the diverter into place carefully, ensuring it is snug but not over-tightened.
- If installing a diverter spout, slide it onto the pipe and tighten the set screw or twist it onto the threaded pipe.
- Reattach any handles or trim pieces removed during the removal process.
Testing the New Diverter for Proper Function
After installation, restore the water supply and check for leaks around the diverter and spout connections. Operate the diverter lever or knob to confirm that water properly switches between the tub faucet and the showerhead.
Pay attention to the following:
- Smooth operation of the diverter without sticking or excessive resistance.
- No dripping or leaking from the faucet or diverter valve.
- Proper water flow through both the tub spout and showerhead when toggled.
If any issues arise, shut off the water supply again and inspect connections or components for correct installation.
Common Types of Bathtub Faucet Diverters and Their Installation Features
Different diverter designs require slightly varied installation methods. Understanding the type you are working with helps ensure a smooth replacement process.
| Diverter Type | Location | Installation Method | Notes |
|---|---|---|---|
| Spout Diverter | On the tub spout | Unscrew spout; replace internal diverter or entire spout | Common and easy to replace; may require plumber’s tape |
| Handle Diverter | Integrated with faucet handle | Remove handle; replace diverter cartridge or valve | May require specialized tools; check manufacturer specs |
| Three-Valve Diverter | Separate valve between hot and cold valves | Remove valve; replace entire diverter valve assembly | Less common; plumbing modifications may be necessary |
| Push-Button or Pull-Up Diverter | On tub spout or faucet | Unscrew spout or handle; replace diverter mechanism | Simple mechanism; watch for wear and corrosion |
Identifying the Type of Bathtub Faucet Diverter
Before beginning the replacement process, it is essential to identify the type of diverter installed on your bathtub faucet. Diverters come in various designs, each requiring a slightly different approach to removal and installation. Common types include:
- Trip Lever Diverter: A lever on the tub spout that you pull up or push down to redirect water.
- Rotary Diverter: A knob on the faucet handle or spout that you turn to switch water flow.
- Push-Button Diverter: A button on the spout or faucet assembly that diverts water when pressed.
- Three-Valve Diverter: Part of a three-handle faucet system, typically located in the middle valve.
Identifying the type will help determine the tools and method needed for removal and installation.
Gathering Necessary Tools and Materials
Having the correct tools and replacement parts ready before starting ensures a smooth and efficient process. Below is a list of commonly required items:
| Tool/Material | Purpose |
|---|---|
| Adjustable Wrench | Loosening and tightening nuts and fittings |
| Screwdrivers (Flathead and Phillips) | Removing screws securing the spout or faucet handles |
| Allen Wrenches | Removing set screws on some faucet handles or spouts |
| Plumber’s Tape (Teflon Tape) | Ensuring leak-free threaded connections |
| Replacement Diverter | New diverter assembly compatible with existing faucet |
| Cleaning Rag and Vinegar Solution | Cleaning mineral deposits and debris |
Confirm compatibility of the replacement diverter with your faucet model, and always turn off the water supply before starting.
Step-by-Step Guide to Removing the Old Diverter
Follow these detailed steps to safely remove the existing diverter from your bathtub faucet:
- Turn Off Water Supply: Locate and shut off the water valves connected to the bathtub to prevent water flow during the replacement.
- Drain Excess Water: Open the faucet handles to relieve pressure and drain any remaining water in the pipes.
- Remove Faucet Handles or Spout Cover: Depending on your faucet type, use the appropriate screwdriver or Allen wrench to remove the handles or spout cover, exposing the diverter mechanism.
- Detach the Diverter: For trip lever or push-button types, unscrew or pull out the diverter assembly carefully. For rotary types, unscrew the diverter knob or cartridge.
- Clean the Area: Use a rag and vinegar solution to remove any mineral deposits, corrosion, or debris from the diverter housing and surrounding areas.
Installing the New Bathtub Faucet Diverter
Installing the new diverter requires precision to ensure a watertight, properly functioning assembly. Follow these instructions:
- Apply Plumber’s Tape: Wrap plumber’s tape around the diverter threads to prevent leaks. Ensure coverage is even and not excessive.
- Insert the New Diverter: Align the new diverter with the faucet assembly and screw it into place, or push it in according to the design. Avoid cross-threading by hand-tightening initially.
- Tighten Securely: Use an adjustable wrench or appropriate tool to tighten the diverter firmly, but avoid over-tightening to prevent damage.
- Reattach Handles or Spout Cover: Replace any removed handles, knobs, or spout covers, securing them with screws or set screws as originally installed.
- Restore Water Supply: Turn the water valves back on and check for leaks around the diverter and faucet assembly.
- Test Diverter Operation: Switch the diverter multiple times to ensure smooth water flow redirection between tub spout and showerhead (if applicable).
Troubleshooting Common Issues After Installation
After installation, some common issues might arise. Address these promptly to maintain proper faucet function:
| Issue | Possible Cause | Recommended Solution |
|---|---|---|
| Diverter Leaks Water | Insufficient plumber’s tape or loose connections | Turn off water, tighten diverter, and reapply plumber’s tape as needed |
| Diverter Does Not Fully Redirect Water | Incorrect installation or damaged diverter cartridge | Remove and inspect diverter, reinstall correctly or replace
