How to Relocate a Toilet Drain

Relocating a toilet drain is a major plumbing project that should only be attempted by experienced DIYers or professional plumbers. However, if you’re up for the challenge, you can save yourself a lot of money by doing the work yourself.

This guide will walk you through the steps of relocating a toilet drain, from start to finish. We’ll cover everything you need to know, from identifying the existing drain location to connecting the new drain to the sewer line.

Identifying the Existing Drain Location

The first step in relocating a toilet drain is to identify the existing drain location. This is usually located in the floor of the bathroom, just below the toilet.

To find the drain, look for a 4-inch or 3-inch pipe that’s capped with a cleanout plug. The cleanout plug is a small, round plug that can be removed to access the drain.

Once you’ve found the drain, mark its location with a piece of chalk or tape. This will help you to keep track of the drain’s location as you work.

Digging a New Trench for the Drain

The next step is to dig a new trench for the drain. The trench should be large enough to accommodate the new drain pipe and any fittings.

The depth of the trench will depend on the location of the sewer line. If the sewer line is located below the frost line, the trench will need to be dug deep enough to prevent the drain pipe from freezing.

The width of the trench should be at least 12 inches. This will give you enough room to work comfortably and to make any necessary adjustments to the drain pipe.

Once you’ve dug the trench, lay a piece of 6-mil plastic sheeting in the bottom of the trench. This will help to protect the drain pipe from any dirt or debris.

Installing the New Drain Pipe

Now it’s time to install the new drain pipe. The new drain pipe should be a 4-inch or 3-inch pipe with a slip joint.

To install the new drain pipe, first slide the pipe into the cleanout plug. Then, use a coupling to connect the new drain pipe to the existing drain pipe.

Make sure that the new drain pipe is level and that the joints are tight.

Connecting the New Drain to the Sewer Line

The final step is to connect the new drain to the sewer line. The sewer line is usually located in the basement or crawl space.

To connect the new drain to the sewer line, you’ll need to use a 45-degree elbow and a length of 4-inch or 3-inch pipe.

First, slide the elbow onto the end of the new drain pipe. Then, connect the other end of the elbow to the sewer line.

Make sure that the joints are tight and that the drain is sloped away from the house.

Testing the New Drain

Once you’ve completed the installation, it’s time to test the new drain. To do this, fill the toilet bowl with water and flush it.

The water should drain quickly and without any problems. If the water doesn’t drain properly, you may need to adjust the slope of the drain pipe or tighten the joints.

Relocating a toilet drain is a major plumbing project, but it’s one that can be completed by DIYers with the right tools and instructions. By following these steps, you can save yourself a lot of money and get the job done right.

Here are some additional tips for relocating a toilet drain:

  • Use a trenching machine to dig the trench. This will save you a lot of time and effort.
  • Make sure that the new drain pipe is supported properly. You can use PVC supports or bricks to support the pipe.
  • Wrap the drain pipe in insulation to protect it from the cold.
  • Caulk around the joints of the drain pipe to prevent leaks.

By following these tips, you can ensure that your new toilet drain is installed properly and that it will last for years to come.

3. Connect the new drain to the existing sewer line.

Once you have cut the old drain and installed the new one, you need to connect the two together. This is a relatively simple process, but it is important to do it correctly so that you don’t have any leaks.

To connect the new drain to the existing sewer line, you will need the following materials:

  • A new drain pipe
  • A coupling
  • A sealant
  • A hacksaw
  • A drill
  • A screwdriver
  • A wrench

Step 1: Cut the new drain pipe to length.

The first step is to cut the new drain pipe to the correct length. To do this, measure the distance from the new drain to the existing sewer line. Then, add a few inches to account for the coupling and sealant.

Once you have the correct length, cut the pipe with a hacksaw.

Step 2: Apply sealant to the coupling.

The next step is to apply sealant to the coupling. This will help to create a watertight seal between the two pipes.

To apply the sealant, simply squeeze a bead of sealant around the inside of the coupling. Then, insert the new drain pipe into the coupling.

Step 3: Connect the pipes together.

Once the sealant is applied, you can connect the two pipes together. To do this, simply screw the coupling onto the new drain pipe.

Step 4: Secure the pipes in place.

Once the pipes are connected, you need to secure them in place. To do this, you can use a clamp or a piece of duct tape.

Step 5: Test the drain.

Once the pipes are secure, you need to test the drain to make sure that it is working properly. To do this, simply run some water down the drain and make sure that it flows freely.

If the drain is not working properly, you may need to adjust the coupling or apply more sealant.

Tips:

  • When cutting the new drain pipe, make sure to cut it at a 45-degree angle. This will help to create a better seal.
  • When applying the sealant, make sure to use a generous amount. This will help to ensure that the seal is watertight.
  • When connecting the pipes together, make sure to tighten the coupling securely. This will help to prevent leaks.
  • When testing the drain, make sure to run enough water to fill the pipes. This will help to flush out any debris that may be blocking the drain.

4. Install a new toilet.

Once you have connected the new drain to the existing sewer line, you can install a new toilet. This is a relatively simple process, but it is important to do it correctly so that you don’t have any leaks.

To install a new toilet, you will need the following materials:

  • A new toilet
  • A wax ring
  • A toilet flange
  • A screwdriver
  • A wrench
  • A hacksaw
  • A drill
  • A plunger

Step 1: Remove the old toilet.

The first step is to remove the old toilet. To do this, you will need to disconnect the water supply line and the sewer line.

To disconnect the water supply line, simply turn off the water supply valve to the toilet. Then, disconnect the water supply line from the toilet.

To disconnect the sewer line, simply unscrew the bolts that hold the toilet to the floor. Then, carefully lift the toilet off of the floor and set it aside.

Step 2: Prepare the toilet flange.

The next step is to prepare the toilet flange. The toilet flange is the metal ring that sits on the floor and supports the toilet.

To prepare the toilet flange, you will need to remove the old wax ring and clean the flange. To remove the old wax ring, simply pry it up with a screwdriver. Then, clean the flange with a rag and some warm water.

Step 3: Install the new toilet flange.

Once the toilet flange is clean, you can install the new one. To do this, simply place the new flange on the floor and secure it with screws.

Step 4: Install the new toilet.

The next step is to install the new toilet. To do this, you will need to place the toilet on the floor and align it with the toilet flange. Then, you will need to connect the water supply line and the sewer line.

To connect the water supply line, simply screw the water supply line onto the toilet. Then, turn on the water supply valve to the toilet.
