Before you rush out to buy a new tub spout shower diverter, let's explore some of the most frequent issues and how you can potentially resolve them. Sometimes, a simple fix is all you need!
Problem 1: Leaky Diverter
A leaky diverter is perhaps the most common complaint. Instead of all the water flowing to the showerhead, you're getting a frustrating mix of shower and tub streams.
Possible Causes:
- Worn-Out O-Ring: The O-ring is a small rubber gasket inside the diverter mechanism. Over time, it can dry out, crack, or become misshapen, leading to leaks.
- Mineral Buildup: Hard water can deposit minerals like calcium and lime around the diverter, interfering with its seal.
- Damaged Diverter Valve: The internal valve itself might be cracked or broken.
Solutions:
- Clean the Diverter: Remove the tub spout (more on that below). Soak the diverter in a solution of white vinegar and water for a few hours to dissolve mineral buildup. Scrub gently with an old toothbrush. Rinse thoroughly before reassembling.
- Replace the O-Ring: This is usually the best first step. You'll need to identify the correct size O-ring for your diverter model. Take the old O-ring to a hardware store for matching. Apply plumber's grease to the new O-ring before installation.
- Check Water Pressure: Excessively high water pressure can overwhelm a slightly worn diverter. A plumber can check and adjust your water pressure if needed.
Problem 2: Stuck or Difficult-to-Pull Diverter
If your diverter is hard to pull up or push down, or if it sticks in one position, it's likely due to friction or corrosion.
Possible Causes:
- Mineral Buildup: Again, hard water can be a culprit.
- Corrosion: Rust or corrosion can develop inside the diverter mechanism.
- Lack of Lubrication: The internal parts may simply need some lubrication.
Solutions:
- Lubricate the Diverter: Apply a small amount of plumber's grease to the diverter mechanism. Work it in by repeatedly pulling and pushing the diverter.
- Clean the Inside of the Spout: Remove the tub spout and clean the interior with a wire brush or scouring pad to remove any rust or scale.
- Replace the Diverter: If lubrication and cleaning don't work, the internal mechanism may be too damaged, and a replacement is necessary.
Problem 3: Diverter Won't Stay Up
This is beyond frustrating! You pull the diverter up, and it immediately slides back down, leaving you with a tub stream instead of a shower.
Possible Causes:
- Worn-Out Diverter: The diverter mechanism has lost its ability to stay in the "up" position.
- Low Water Pressure: Believe it or not, sometimes low water pressure can prevent the diverter from staying up, especially on older models that rely on water pressure for a tighter seal.
- Faulty Internal Spring: Some diverters use a spring to maintain their position. This spring may have weakened or broken.
Solutions:
- Check Water Pressure: Ensure your water pressure is adequate. If it's too low, contact a plumber to investigate.
- Replace the Diverter: In most cases, a worn-out diverter that won't stay up requires replacement.

If you've exhausted the troubleshooting steps and determined that a replacement is necessary, here's how to do it:
Tools You'll Need:
-
New Tub Spout with Diverter: Make sure it's compatible with your plumbing connections.
Recommended Product: Delta Faucet RP5833 Tub Spout with Pull-Up Diverter. This model features a durable construction, easy installation, and a reliable diverter mechanism, making it a popular choice for homeowners. Its universal fit often works with various plumbing setups.
-
Plumber's Grease: For lubricating O-rings and threads.
-
Adjustable Wrench: For loosening the old spout and tightening the new one.
-
Screwdriver (if applicable): Some spouts are secured with a set screw.
-
Clean Rags: For wiping up water and protecting surfaces.
-
Pencil or Marker: To mark the position of the old spout.
Step 1: Turn Off the Water Supply
Locate the shut-off valves for the bathtub. These are usually located behind an access panel or in the basement. Turn off both the hot and cold water supplies. If you can't find individual shut-off valves, turn off the main water supply to your house.
Step 2: Remove the Old Tub Spout
The method for removing the old spout depends on its type:
-
Slip-On Spout with Set Screw: Look for a small set screw on the underside of the spout, near the wall. Use a screwdriver to loosen the set screw. Then, twist and pull the spout straight off the pipe.
Pro Tip: Some set screws are deeply recessed. You might need a long, thin screwdriver to reach it.
-
Threaded Spout: These spouts are screwed onto a threaded pipe. Grab the spout firmly with an adjustable wrench and turn it counterclockwise to unscrew it.
Pro Tip: Wrap the spout with a rag to protect the finish from scratches.
-
Slip-On Spout (No Set Screw): These are the trickiest. They are held in place by friction. Carefully twist and pull the spout. You may need to use a bit more force, but be careful not to damage the pipe behind the wall.
Pro Tip: If it's stuck, try gently tapping around the base of the spout with a rubber mallet to loosen it. You can also try applying heat from a hairdryer to expand the spout slightly.
Step 3: Clean the Pipe
Once the old spout is removed, clean the exposed pipe thoroughly. Remove any old sealant, corrosion, or debris.
Step 4: Prepare the New Tub Spout
-
Slip-On Spout: Apply a generous amount of plumber's grease to the inside of the new spout. This will make it easier to slide onto the pipe and create a good seal.
-
Threaded Spout: Wrap the threads of the pipe with Teflon tape (plumber's tape). This will help to create a watertight seal.
Step 5: Install the New Tub Spout
-
Slip-On Spout: Align the spout with the pipe and push it firmly into place. If it has a set screw, tighten the set screw securely to hold the spout in position. Refer back to the old markings you made to make sure this is where the new spout ends up.
-
Threaded Spout: Align the spout with the threads of the pipe and turn it clockwise until it is snug. Do not overtighten.
Step 6: Test the New Diverter
Turn the water supply back on slowly. Check for leaks around the base of the spout. Pull up on the diverter knob and make sure the water flows freely from the showerhead. If there are any leaks, tighten the spout or reapply Teflon tape.
