Introduction
A shower diverter plays an essential role in directing water flow between your bathtub faucet and showerhead. If it’s not working properly, you may notice that water is coming out of both the faucet and the showerhead at the same time, or perhaps no water is coming from the showerhead at all. Fixing a faulty diverter is usually a straightforward process that can save you from bigger plumbing issues down the road.
In this guide, we’ll walk you through how to identify the problem, gather the right tools, and repair or replace your shower diverter.
What is a Shower Diverter?
A shower diverter is a valve that allows you to switch the water flow from the bathtub spout to the showerhead. It’s typically located on the tub’s faucet or as a separate lever on the wall. Depending on the type of diverter, you either pull up a knob, turn a lever, or push a button to redirect water to the showerhead.
Types of Shower Diverters
There are three common types of shower diverters:
- Three-Valve Diverter: Found in showers with separate hot and cold taps. The third valve diverts water to the showerhead.
- Two-Valve Diverter: Often found in single-handle faucets, allowing for a combined adjustment of water temperature and flow.
- Single-Valve Diverter (Tub Spout Diverter): The most common type, located directly on the tub spout. You lift a knob or pull a lever to switch the water flow.
Common Problems with Shower Diverters
Shower diverters can experience various issues, including:
- Sticking Diverter: The diverter is hard to pull or push and doesn’t switch properly.
- Leaking Water: Water leaks from both the spout and the showerhead, or water drips even when the diverter is engaged.
- Loose or Broken Handle: The diverter handle may feel loose or break off entirely, preventing you from using it.
Tools and Materials Needed
Before you begin repairing your shower diverter, gather the necessary tools and materials:
- Adjustable wrench or pliers
- Screwdrivers (flathead and Phillips)
- Plumber’s tape
- Replacement diverter parts (if needed)
- Lubricating oil or plumber’s grease
- Old cloth or rag
- Allen key (for some models)
- A cup or small container (to catch any water)
Step-by-Step Guide to Fixing a Shower Diverter
Step 1: Turn Off the Water Supply
Before you start working on the shower diverter, turn off the water supply to the bathroom. You don’t want water gushing out when you disassemble the faucet. This can usually be done by turning off the main water valve in your home or using the shutoff valves behind the shower or under the sink.
Step 2: Inspect the Diverter Handle
If the diverter is on the tub spout, check if the handle is loose or damaged. If so, unscrew and remove the handle using a screwdriver. Some models may have a small set screw underneath the handle, which can be removed with an Allen key. Once the handle is off, inspect the diverter mechanism for wear or damage.
Step 3: Remove the Diverter Valve
For diverters located within the tub spout, you’ll need to remove the spout. Use an adjustable wrench or pliers to loosen and unscrew the spout from the pipe. For in-wall diverters, use a screwdriver to remove the trim plate and access the valve.
Step 4: Inspect and Clean the Diverter
Once the diverter valve is exposed, check for debris, mineral buildup, or corrosion, which can cause it to stick. Clean the valve thoroughly using an old cloth or rag. For stubborn mineral buildup, a vinegar soak can help dissolve the deposits.
Step 5: Replace Worn-Out Parts
If the valve is damaged or worn, it’s time to replace it. Take the old diverter to a hardware store to find a suitable replacement. Install the new diverter valve by screwing it into place, applying plumber’s tape to the threads to ensure a watertight seal.
Step 6: Reassemble and Test the Diverter
Once the new or cleaned diverter is in place, reassemble the spout or trim plate and reinstall the handle. Turn the water supply back on and test the diverter to ensure it’s switching between the spout and showerhead without leaks or issues.
How to Fix a Stuck Shower Diverter
A stuck shower diverter is a common issue caused by wear or mineral buildup. To fix this:
- Loosen the Diverter: Apply some force to pull up or push down the stuck diverter knob. If it’s still hard to move, remove the diverter following the steps above.
- Lubricate the Mechanism: Once removed, apply plumber’s grease or lubricating oil to the moving parts to free up the mechanism. Clean any dirt or mineral deposits before reinstalling.
Fixing a Leaking Shower Diverter
A leaking shower diverter typically means the seals or gaskets are worn out. Here’s how to fix it:
- Remove the Diverter Valve as described above.
- Inspect the Rubber Seals and Washers: If they are cracked or worn, replace them with new ones.
- Reassemble the Diverter: Reinstall the valve with the new seals and washers in place, and apply plumber’s tape to the threads for a good seal.
Replacing a Shower Diverter
If your diverter is severely damaged or beyond repair, replacement is the best option. Here’s how:
- Turn off the Water: Shut off the water supply to the bathroom.
- Remove the Old Diverter: Follow the steps above to remove the diverter valve or spout.
- Install the New Diverter: Purchase a compatible replacement valve or spout. Apply plumber’s tape to the threads and screw the new diverter into place.
- Test the New Diverter: Turn the water supply back on and test the diverter for proper operation.
Maintaining Your Shower Diverter
Prevent future issues by:
- Cleaning the Diverter Regularly: Wipe down the diverter and spout to remove soap scum and mineral deposits.
- Inspecting the Seals: Periodically check the rubber washers and seals for wear.
- Lubricating the Mechanism: Apply plumber’s grease to the diverter parts during regular maintenance.
When to Call a Professional
If the diverter is still not working after repairs or you’re dealing with a more complex plumbing system, it’s time to call a plumber. A professional can identify deeper issues, such as problems with water pressure or faulty installation, and make sure the system is safe and secure.
Safety Precautions
When working on your shower diverter, keep these safety tips in mind:
- Turn off the water supply before starting any repair work.
- Use caution with tools, especially when removing and reinstalling parts, to avoid damaging pipes or fixtures.
- Wear protective gloves if you’re dealing with sharp tools or cleaning chemicals.
Cost of Fixing a Shower Diverter
- DIY Repair Costs: If you're repairing the diverter yourself, expect to spend $10 to $30 on replacement parts like seals or washers.
- Professional Repair Costs: Hiring a plumber to replace or repair a diverter can cost anywhere from $75 to $150, depending on the complexity of the issue and your location.
How Long Should a Shower Diverter Last?
A well-maintained shower diverter can last 5 to 10 years. The lifespan depends on water quality (hard water can cause more wear) and how often the diverter is used. Regular cleaning and inspection can help extend its life.
Conclusion
Fixing a shower diverter is a manageable DIY task that can save you from larger plumbing problems and water waste. Whether it’s a stuck diverter, a leaking valve, or a completely broken mechanism, following these steps will help you get your shower back in working order. Regular maintenance is key to keeping your diverter in good shape for years to come.
