Before you start wrenching away, you need to figure out what kind of overflow drain you have. There are two main types:
- Trip Lever Overflow: This is the most common type. It has a lever or knob on the overflow plate that you flip to open or close the drain stopper.
- Lift and Turn Overflow: This type has a knob or cap that you lift and turn to operate the drain stopper.
Knowing which type you have will influence the specific steps involved in the repair.

Having the right tools on hand will make the job much easier. Here's what you'll likely need:
- Flathead Screwdriver: For removing the overflow plate and possibly adjusting the linkage.
- Phillips Head Screwdriver: Some overflow plates use Phillips head screws.
- Pliers: To grip and manipulate the drain linkage or stopper. Channel-lock pliers are especially helpful.
- Penetrating Oil (e.g., WD-40): To loosen corroded or stuck parts.
- New Overflow Gasket (or Plumber's Putty): To ensure a watertight seal.
- New Overflow Drain Assembly (optional): If the existing drain is badly damaged or corroded, you might need to replace the entire assembly.
- Clean Rags: To wipe up messes.
- Work Gloves: To protect your hands.
- Flashlight or Headlamp: To see into the drain opening.

While you won't be working directly with the water supply, it's always a good idea to turn off the water to the bathroom just in case something goes wrong. This will prevent any accidental flooding. You can usually find the shut-off valves under the sink or in a nearby utility closet.
<br><br><a href="https://www.amazon.com/s?k=tub overflow drain&sort=relevancerank&tag=bestbathroomrenovation-20">[Explore Top Rated tub overflow drain on Amazon.]</a><br><br>## Step 4: Remove the Overflow Plate
The first step in accessing the drain mechanism is to remove the overflow plate. This is the plate with the lever or knob located near the top of the tub.
- Use the appropriate screwdriver (flathead or Phillips) to remove the screws holding the overflow plate in place.
- Be careful not to drop the screws down the drain!
- Once the screws are removed, gently pull the overflow plate away from the tub wall. It may be stuck due to old caulk or grime.

If you have a trip lever overflow, the overflow plate is connected to a linkage that operates the drain stopper.
- Carefully examine the linkage for any signs of damage or corrosion. Look for broken or bent parts, loose connections, or excessive rust.
- The most common problem with trip lever overflows is a loose or disconnected linkage. This can prevent the stopper from opening or closing properly.
- If the linkage is simply loose, try tightening the screws or adjusting the linkage to restore proper function. Refer to the product manual for detailed instructions.

Now, we need to remove the stopper to inspect it and clean the drain. The method for removing the stopper will depend on the type of overflow drain you have.
- Trip Lever Overflow: After removing the overflow plate, you should be able to pull the entire linkage and stopper assembly out of the overflow drain opening. You might need to wiggle it gently or use pliers to grip the linkage and pull it out.
- Lift and Turn Overflow: These can be a bit trickier. Some lift-and-turn stoppers simply lift out, while others require you to unscrew the knob or cap. Look for a small set screw on the side of the knob. If you find one, loosen it with a small Allen wrench or screwdriver and then try lifting the stopper out.
If the stopper is stuck, try spraying it with penetrating oil and letting it sit for a few minutes before attempting to remove it.

Once you've removed the stopper, take a good look at it. It's likely covered in hair, soap scum, and other gunk.
- Use an old toothbrush, pliers, or a small hook to remove all the debris from the stopper.
- Rinse the stopper thoroughly with water.
- Now, clean the inside of the drain opening. You can use a bent wire hanger, a drain snake, or a specialized drain cleaning tool to remove any buildup.
- Flush the drain with hot water to clear away any remaining debris.

The overflow gasket is the rubber or foam ring that sits behind the overflow plate and seals the connection between the plate and the tub wall. Over time, this gasket can dry out, crack, or crumble, leading to leaks.
- Inspect the overflow gasket for any signs of damage.
- If the gasket is damaged, remove it and replace it with a new one. You can usually find replacement gaskets at your local hardware store.
- If you can't find a replacement gasket, you can use plumber's putty as a substitute. Roll the putty into a rope and press it around the back of the overflow plate before reattaching it to the tub wall.

Now that you've cleaned and inspected all the parts, it's time to reassemble the overflow drain.
- Insert the stopper back into the drain opening. Make sure it's properly aligned and that it moves freely.
- If you have a trip lever overflow, reattach the linkage to the overflow plate. Make sure all the connections are secure.
- Carefully position the overflow plate against the tub wall, making sure the overflow gasket (or plumber's putty) is properly seated.
- Reinstall the screws that hold the overflow plate in place. Tighten the screws securely, but be careful not to over-tighten them, as this could crack the tub.

After reassembling the overflow drain, test it to make sure it's working properly.
- Fill the tub with a few inches of water.
- Operate the drain stopper (either by flipping the lever or lifting and turning the knob).
- Check for leaks around the overflow plate and the drain opening.
- If you see any leaks, tighten the screws on the overflow plate or reapply plumber's putty.
