How To Fix A Leaking Bathtub Overflow Drain – Detail Guide

A leaky bathtub’s issues are frequently linked to the overflow tube or overflow drain assembly. A safety precaution, the overflow tube prevents water from overflowing the tub’s edge by directing it back down into the drain pipes. However, if the overflow tube fittings come loose, water may leak out and seep beneath the tub, thereby damaging the floor or the ceiling of the room where the tub is located.

But a tub leak arises, the first instinct is frequently to rip out the ceiling from below in an effort to remedy the drain trap, when in fact, the overflow tube may only need to be tightened or a new gasket installed. If you regularly bathe with the water level relatively high or if you have energetic kids who splash water around as they bathe, the overflow drain is very likely the cause of your leak. How To Fix A Leaking Bathtub Overflow Drain?

Issues with the bath overflow drain’s common causes

Sometimes you don’t notice something in your home isn’t functioning well until an issue emerges as a result of it. One such example is the overflow drain from your bath. Here are a few of the most frequent reasons why it doesn’t function properly.

It’s leaky in the overflow tube

It is obvious that there is a problem with the overflow drain when water pools in your ceiling after running the bath for longer than necessary. Sometimes, a small leak can result in such havoc and harm.

If an overflow drain bursts, water may seep onto your bathroom floor from the drain pipe. This results in it going up in your ceiling and down into the main area of your two-story house because of this.

The Drain Overflow is Clogged

We have emergency plumbers because things go wrong and plumbing doesn’t always work perfectly. Over time, debris and soap scum might clog your overflow drain. That is true, but you don’t realize it until you start forgetting to take a bath.

You Enjoy Long Baths

There is absolutely no better way to unwind after a long day of tension than with a leisurely soak in a hot tub. Although it is their intended use, there is such a thing as too much good. These deep tubs have the potential to immerse your overflow plate, which could potentially reduce your drain’s capacity.

Keep those extended soaks to a minimum to lessen the possibility of flooding your bathroom and doing serious damage.

There is Permanent Damage to the Overflow Gasket

Gaskets are extremely durable and powerful, but they aren’t built to endure forever. They could decay and crack with time. Water may end up exiting the overflow drain when they aren’t functioning properly.

The bathtub was left running

We understand that life is busy. You’re running a bath when the kids suddenly ask for your attention. You suddenly have a flood on your hands because your tub’s drain is overloaded.

Water from your shower drenches the cover plate

You might have an overflow drain issue if the water in your shower keeps running over the cover plate. You might be able to stop this from becoming an issue by changing the angle.

Before You Begin

Discover the leak’s origin. Start by inspecting the tile for problems with the caulking and grout. These only cause leaks while the shower or bathtub is in use. Prior to assuming that plumbing repairs are necessary, these should be addressed.

It might be a pressured water line leak if the leak is continuous and appears to be coming from the walls or flooring. This implies that even when the bathtub or shower is not in use, water would still be leaking. In that scenario, the overflow tube is not the issue.

If there is a leak in the drain line, it will only become apparent while the shower or bathtub is being used. To reveal the tub’s plumbing connections, remove any access hatches or panels you may have. When the tub is filled with water, check beneath it for any leaks. If you notice water escaping, it’s extremely likely that the drain fitting or the drain trap beneath the tub have weak connections. If necessary, tighten them or fix them.

Run the shower if the tub’s flowing water doesn’t create any leaks. Look for evidence of water spilling onto the showerhead, tub spout, or faucet escutcheon plate if you believe there is leaking from the faucet (valve plate). Water can leak behind the shower wall due to cracked or missing caulk around these components.

The overflow tube is most likely to be at fault if the shower test does not disclose any leaks.

What you’ll require

  • Resources / Tools
  • Screwdrivers
  • Useful knife
  • Ratchet-nosed pliers (if needed)
  • Materials
  • Rub alcohol with
  • substitute overflow gasket (as needed)
  • sizing caulk (as needed)


Step 1: Overflow Gasket Inspection

A ring-shaped gasket that normally sits between the flange surrounding the pipe opening and the interior of the tub wall serves as the seal between a tub overflow pipe and the tub. Rubber or neoprene, the material used for the gasket, might dry up and split over time, which can cause leaks.

Remove the overflow plate to inspect the overflow gasket. To accomplish this, take out the screw(s) that are holding the plate in place, then peel off the plate. Before the caulking around the overflow plate will come off, you might need to cut some of it away. Utilizing a utility knife, cut the caulk.

Examine the gasket. Replace it if it is severely damaged, cracked, or crushed. If you’re unsure, it’s a good idea to replace the gasket to eliminate that possibility as a leak source. You can discover that the overflow pipe assembly is damaged or loose during the inspection. If so, replacing the entire overflow assembly with brand-new components is a simple fix.

Tip: To the stopper assembly for the tub drain are some overflow plates. In this situation, carefully raise and remove the assembly from the drain aperture. The bottom of most assemblies has a cylindrical stopper that is attached to a long, thin rod. You might need to hire a pro if the drain needs to be replaced: Cutting through a wall or floor may be necessary to remove drain and plumbing waste lines, which is a common step in the replacement of a drain. The process is made more difficult by the addition of overflow drains that are connected to the tub waste line.

Step 2: Take Out the Previous Overflow Gasket

Remove the old gasket before replacing one that is worn out or broken. You can push the overflow drain pipe backward (away from the tub) if it has some give so that you can reach in and grab the gasket with your fingers or needle-nose pliers. To get rid of any dirt and debris, remove the entire old gasket and use a rag and rubbing alcohol to clean the area surrounding the tub hole and the drain pipe flange.

Put in the fresh gasket.
When fitting the new gasket against the flange surrounding the drain pipe opening, carefully push it into the hole in the tub wall. To ensure a uniform seal against the tub, make sure it is completely seated against the flange.

To accommodate the tub wall’s angle, overflow gaskets are frequently tapered; to use the taper properly, follow the manufacturer’s instructions.

Step 3: The Overflow Plate back into place

Reinstall the overflow plate, making that the opening—through which the overflowing water flows—is at the bottom. The stopper should be gently inserted into the overflow pipe if the plate has one, and the rod should be lowered until the plate touches the drain aperture.

Utilize the plate’s screw(s) to affix it. If there are two screws, alternate between tightening them one at a time in order to pressure the gasket against the tub equally.

Tip: The best approach to test the replacement gasket (or other overflow fixes) is to completely fill the tub and allow some water to overflow into it. You can postpone doing this until after your subsequent bath in order to save a lot of water.

Step 4: Tips for Troubleshooting Tub Overflow

There are some alternative methods you can attempt if the overflow gasket is in good shape or if changing the gasket does not appear to halt the leak:

Make sure the gasket is properly attached and that the tub overflow drain has it in the center.
Check the tub’s edge near the overflow plate for corrosion or nicks that could allow water to leak in from behind it.
Verify that the overflow plate is screwed down firmly and that the plate’s notch is facing downward.
To guarantee that water cannot enter beyond the shower surround, inspect the seal on all other shower components, remove peeling and outdated caulk, and apply fresh caulk as necessary.

A Bath overflow could damage my home

  • Bathroom flooring has been harmed, including the tile and subfloor.
  • Below the bathroom, there are stained ceilings and warped tiles.
  • Electrical issues with ceiling light fixtures and overhead wiring
  • Below the bathtub, the walls and ceiling are stained with water.
  • Drywall and wood framing on lower floors have structural problems.
