How to Fix a Bathtub Drain Leak

A bathtub drain leak can be a frustrating problem, but it’s one that you can usually fix yourself with a few simple tools and some elbow grease.

This guide will walk you through the steps of identifying the source of the leak, draining the tub, and repairing the leak.

Identifying the Source of the Leak

The first step to fixing a bathtub drain leak is to identify the source of the leak. This can be done by looking for signs of water damage around the drain, such as:

  • Dampness or mold
  • Water stains
  • Peeling paint
  • Soft or rotting wood

You can also listen for the sound of running water when the drain is not in use. If you hear water running, even if it’s just a trickle, this is a good indication that there is a leak.

Finally, you can feel around the drain for any loose or damaged parts. If you find any loose or damaged parts, this is likely the source of the leak.

Draining the Tub

Once you have identified the source of the leak, you will need to drain the tub. This can be done by turning off the water supply to the tub and removing the drain plug.

If the drain is clogged, you may need to use a plunger or a drain snake to clear the clog before you can drain the tub.

Once the tub is drained, you can begin to repair the leak.

Repairing the Leak

The specific steps for repairing a bathtub drain leak will vary depending on the source of the leak. However, some common repairs include:

  • Replacing a leaky drain gasket: If the drain gasket is worn or damaged, it can allow water to leak around the drain. To replace the drain gasket, you will need to remove the old gasket and install a new one.
  • Replacing a cracked or broken drain flange: The drain flange is the metal ring that sits around the drain and holds it in place. If the drain flange is cracked or broken, it can allow water to leak around the drain. To replace the drain flange, you will need to remove the old flange and install a new one.
  • Replacing a damaged drain pipe: If the drain pipe is damaged, it can allow water to leak into the wall or floor. To replace the drain pipe, you will need to cut out the damaged section of pipe and install a new section of pipe.

Once you have repaired the leak, you will need to re-attach the drain plug and turn the water supply back on.

Fixing a bathtub drain leak is a relatively simple task that can be completed in a few hours. By following the steps in this guide, you can save yourself the time and money of hiring a plumber.

Here are some additional tips for preventing bathtub drain leaks:

  • Keep the drain clean and free of debris.
  • Use a drain strainer to catch hair and other debris.
  • Replace the drain gasket and drain flange regularly.
  • Repair any damaged drain pipes promptly.

By following these tips, you can help to keep your bathtub drain leak-free for years to come.

Replacing the Drain Pipe

If the drain pipe is leaking, you will need to replace it. To do this, you will need to:

1. Turn off the water supply to the bathtub. This can usually be done by turning off the main water valve located near the water heater.
2. Drain the water from the bathtub. You can do this by removing the drain plug and letting the water drain out.
3. Remove the old drain pipe. The drain pipe is usually located under the bathtub. It is held in place by a setscrew or nut. Use a wrench to loosen the setscrew or nut and remove the drain pipe.
4. Install the new drain pipe. The new drain pipe should be the same size as the old drain pipe. Slide the new drain pipe into place and tighten the setscrew or nut to secure it.
5. Turn on the water supply to the bathtub.
6. Check for leaks. Run the water in the bathtub and look for any leaks around the drain pipe. If you see any leaks, tighten the setscrew or nut until the leak stops.

Replacing the Drain Hardware

If the drain hardware is damaged, you will need to replace it. To do this, you will need to:

1. Turn off the water supply to the bathtub. This can usually be done by turning off the main water valve located near the water heater.
2. Drain the water from the bathtub. You can do this by removing the drain plug and letting the water drain out.
3. Remove the old drain hardware. The drain hardware is usually held in place by a setscrew or nut. Use a wrench to loosen the setscrew or nut and remove the drain hardware.
4. Install the new drain hardware. The new drain hardware should be the same size as the old drain hardware. Slide the new drain hardware into place and tighten the setscrew or nut to secure it.
5. Turn on the water supply to the bathtub.
6. Check for leaks. Run the water in the bathtub and look for any leaks around the drain hardware. If you see any leaks, tighten the setscrew or nut until the leak stops.

Applying a Plumbing Sealant

Once the new drain hardware is installed, you can apply a plumbing sealant around the drain to prevent future leaks. To do this, you will need to:

1. Apply a thin layer of plumbing sealant around the drain. Make sure to apply the sealant evenly and to cover all of the gaps around the drain.
2. Allow the sealant to dry completely. This usually takes about 24 hours.
3. Turn on the water supply to the bathtub.
4. Check for leaks. Run the water in the bathtub and look for any leaks around the drain. If you see any leaks, apply more sealant until the leak stops.

By following these steps, you can easily fix a bathtub drain leak. If you are not comfortable doing this yourself, you can always hire a professional plumber to do the job for you.
