4 Steps to Plumbing a Tub Drain

4 Steps to Plumbing a Tub Drain

Fixing a leaky tub drain can be a daunting task, but it’s actually a relatively simple plumbing repair that you can do yourself with a few basic tools and materials. The key is to have a clear understanding of how a tub drain works and the steps involved in removing and replacing the drain assembly. In this article, we’ll walk you through the process of how to plumb a tub drain, from start to finish. We’ll also provide detailed instructions, tips, and troubleshooting advice to help you get the job done right.

First, you need to understand that a tub drain assembly consists of several components, including a drain stopper, a drain body, a drain shoe, and a drainpipe. The drain stopper is the part that you use to plug the drain, while the drain body is the cylindrical part that connects the drain stopper to the drainpipe. The drain shoe is a rubber gasket that helps to create a watertight seal between the drain body and the tub. Finally, the drainpipe is the pipe that carries wastewater from the tub to the main drain line. When any of these components becomes damaged or worn, it can cause water to leak from the drain.

To fix a leaky tub drain, you’ll need to remove the old drain assembly and replace it with a new one. The process is relatively simple and can be completed in a few hours. However, it’s important to make sure that you have the right tools and materials before you start. You’ll also need to be prepared to get a little wet, as there may be some water that leaks out when you remove the old drain assembly. Once you have everything you need, follow the steps in this article to get the job done right.

Choosing the Right Drain

Selecting the appropriate drain for your bathtub is crucial for both efficient drainage and a cohesive aesthetic appeal. Consider the following factors when making your choice:

Drain Type

Type Description
Pop-Up Drain A classic drain that operates by pressing down on a stopper to open or close the drain.
Toe-Touch Drain A convenient drain that opens and closes by lightly pressing on it with your toe.
Waste-and-Overflow Drain A combination drain that includes an overflow hole to prevent water from spilling over the bathtub’s edge.

Material

Drains are typically made from durable materials like brass, stainless steel, or plastic. Brass and stainless steel are more resistant to corrosion and tarnishing, while plastic drains are more budget-friendly.

Finish

The finish of the drain should complement the bathtub and other bathroom fixtures. Popular finishes include chrome, brushed nickel, bronze, and oil-rubbed bronze.

Size and Style

Choose a drain that fits the diameter of your bathtub’s drain hole. Drains come in various styles, from traditional to contemporary, to match the overall design of your bathroom.

Additional Features

Some drains offer additional features, such as built-in hair strainers to prevent clogs and decorative trim to enhance the drain’s appearance.

Removing the Old Drain

Before you can install a new tub drain, you must remove the old one. This is a relatively simple process, but it is important to follow the steps carefully to avoid damaging the tub or drainpipes. Here are the steps on how to remove an old tub drain:

1. Gather your tools.

You will need a few tools to remove the old tub drain, including a pair of pliers, a screwdriver, and a bucket. It will be helpful to place a bucket under the drain to catch any water that may leak out when you remove the drain.

2. Remove the overflow plate.

The overflow plate is the small, round plate located near the top of the tub. It is held in place by a few screws. Use a screwdriver to remove the screws, and then pull the overflow plate off. Make sure the drain stopper is open before removing the overflow plate.

3. Remove the drain stopper.

4. Remove the drain body.

The drain body is the main part of the drain assembly. It is located under the tub. Use a pair of pliers to loosen the nut that holds the drain body in place. Once the nut is loose, you can pull the drain body out of the tub.

5. Clean the drainpipes.

Once the old drain is removed, it is important to clean the drain pipes. This will help to prevent clogs and other problems. Use a drain cleaner or a plumber’s snake to clean the pipes. Using a wet/dry vacuum to suck up any remaining water or debris in the pipe is also recommended.

Cleaning the Drain Hole

If the drain hole is clogged, you can use a drain snake to clear it. Insert the drain snake into the drain hole and push it down until it reaches the clog. Rotate the drain snake back and forth to break up the clog. Once the clog is broken up, flush the drain with hot water to remove the debris.

You can also use a chemical drain cleaner to clear a clogged drain hole. Pour the drain cleaner into the drain hole and let it sit for the amount of time specified on the product label. Flush the drain with hot water to remove the drain cleaner and debris.

If the drain hole is still clogged, you may need to call a plumber to have it professionally cleaned.

Here are some tips for preventing a clogged drain hole:

Tip Explanation
Don’t pour grease or food down the drain. Grease and food can build up in the drain and cause a clog.
Use a drain strainer to catch hair and other debris. Hair and debris can build up in the drain and cause a clog.
Flush the drain with hot water regularly. Hot water can help to dissolve grease and soap scum that can build up in the drain.

Installing the Pop-Up Assembly

The pop-up assembly is the mechanism that allows you to open and close the drain of your tub. It consists of a pop-up stopper, a lift rod, and a drain assembly. Installing the pop-up assembly is a relatively simple process, but it is important to follow the instructions carefully to ensure that it is installed correctly.

To install the pop-up assembly, you will need the following materials:

  • Pop-up stopper
  • Lift rod
  • Drain assembly
  • Plumber’s putty
  • Wrench
  • Screwdriver

Once you have gathered your materials, you can follow these steps to install the pop-up assembly:

Step 1: Remove the old pop-up assembly. To do this, remove the screws that hold the pop-up stopper in place and pull the stopper out of the drain assembly. Then, remove the lift rod from the drain assembly.

Step 2: Apply a bead of plumber’s putty to the rim of the drain assembly. This will help to create a watertight seal between the drain assembly and the tub.

Step 3: Insert the drain assembly into the drain hole in the tub. Be sure to align the drain assembly so that the overflow hole is at the top.

Step 4: Hand-tighten the drain assembly until it is snug. Do not overtighten the drain assembly, as this could damage the tub.

Step 5: Install the lift rod into the drain assembly. To do this, insert the end of the lift rod into the hole in the drain assembly and push it down until it clicks into place.

Step 6: Install the pop-up stopper. To do this, insert the pop-up stopper into the drain assembly and push it down until it clicks into place. Be sure to align the pop-up stopper so that the handle is facing the front of the tub.

Mistake How to Avoid

Installing the pop-up stopper incorrectly Be sure to align the pop-up stopper so that the handle is facing the front of the tub.
Not applying plumber’s putty to the rim of the drain assembly Apply a bead of plumber’s putty to the rim of the drain assembly. This will help to create a watertight seal between the drain assembly and the tub.

Connecting the Drainpipe

Step 7: Inspect and Seal the Drain

Once the drainpipe is connected, inspect the entire assembly carefully for any leaks or gaps. Use plumbers putty or silicone sealant to fill any small gaps around the drainpipe or drain flange. Apply a generous amount of sealant around the base of the drain flange, where it meets the tub and the drainpipe, and smooth it out with your finger or a putty knife. This will ensure a watertight seal and prevent water from seeping out and causing damage.

Tips for Sealing the Drain:

Tip Reason
Use non-hardening plumbers putty or silicone sealant. Hardening sealants can crack over time, allowing water to leak.
Apply a generous amount of sealant. A thin seal may not be enough to prevent leaks.
Smooth out the sealant thoroughly. Any gaps or air pockets in the sealant can allow water to penetrate.
Allow the sealant to cure completely. Before using the tub, allow the sealant to cure according to the manufacturer’s instructions.

Testing the Drain

After assembling the drain, you’ll want to test it for leaks. To do this, plug the overflow drain (if there is one) and fill the tub with water until it reaches the overflow hole. Let the water run for a few minutes, then check for any leaks around the drain assembly. If you see any leaks, tighten the nuts on the drainpipe connections. If the leaks persist, you may need to replace the washers or the drainpipe itself.

Once the drain has been tested and is leak-free, you can install the drain cover and the tub stopper. To install the drain cover, simply place it over the drain opening and press down until it snaps into place. To install the tub stopper, insert the stopper into the drain opening and turn it clockwise until it is secure.
