Moving a toilet drain on the second floor can be a daunting task, but it’s not impossible. This article serves as your guide, providing a step-by-step walkthrough to help you conquer the plumbing puzzle. It’s like having a seasoned plumber right beside you, offering guidance every step of the way.
Understanding the Challenge: Second Floor Plumbing
Moving a toilet drain on the second floor presents a unique set of challenges. Unlike moving a drain on the ground floor, you’re dealing with gravity’s limitations. The drain needs to be lower than the toilet to allow for proper drainage. This often necessitates adapting existing plumbing or even running new lines.
First things first: safety! This project requires a thorough understanding of plumbing principles and safety practices. If you’re unfamiliar with working with plumbing systems, it’s best to consult a licensed plumber. Remember, a small mistake can lead to bigger, and more costly, problems.
Preparing for the Plunge
1. Materials and Tools
- PVC Pipe and Fittings: Choose the right size depending on your existing system. You’ll need elbows, tees, and straight pipe sections to adapt the drain line.
- PVC Cement: Securely joins PVC pipes and fittings.
- Measuring Tape: Accuracy is crucial when it comes to plumbing dimensions.
- Level: Ensure a smooth, level run for your drain pipe.
- Pipe Cutter: Cleanly cuts PVC pipe to the required length.
- Primer and Cleaner: Prepares PVC surfaces for bonding with cement.
- Drain Auger: Clears any obstructions in the existing drain line.
- Safety Glasses: Protect your eyes from debris.
- Gloves: Protect your hands from chemicals and sharp edges.

2. Planning is Key
Before you get your hands dirty, spend some time plotting a course for your new drain.
- Map It Out: Sketch the new drain line’s route on your floor plan. Identify the shortest, most feasible path, considering the existing plumbing and the new toilet location.
- Obstruction Check: Inspect the area for obstacles like pipes, walls, beams, or electrical lines.
- Pipe Slope Calculation: Ensure your drain pipe has the correct slope for proper water flow. (一般トイレ排水管は1/4インチの勾配が必要です)
- Consider Existing Lines: Identify the existing drain line (you might need to test with water to confirm) and determine if you can adapt it or if a new line is necessary.
The Journey Begins: Moving the Toilet Drain
1. Turn Off the Water Supply
Safety first! Locate the main water shut-off valve and turn it off completely. This prevents flooding during the work.
2. Disconnect and Remove the Existing Toilet
- Flush the toilet: To empty the bowl and tank.
- Turn off the water supply: Locate the water supply valve to the toilet and close it.
- Disconnect the toilet supply line: Carefully unscrew the flexible hose connecting the toilet to the water supply.
- Disconnect the drain line: If you’re repositioning the drain, you’ll need to disconnect the existing pipe below the toilet.
- Remove the toilet: Gently lift and remove the toilet from its position.
3. Clean and Inspect the Existing Drain
- Clear any obstructions: Inspect the existing drain line with a drain auger to remove any debris or blockages.
- Visualize the path: Ensure the existing drain line’s condition is suitable for adapting or replacing.
4. Choose the Right Method: Adaptation vs. New Drain
- Adaptation: If the existing drain line is accessible and in good condition, you can adapt it. Consider using PVC elbows, tees, and straight pipe segments to create the new drain line’s path.
- New Drain: If you need to extend the drain line significantly or the existing line is damaged, you’ll need to install a new one.
5. Run the New Drain Line
- Measure with precision: Using a measuring tape, determine the precise lengths of PVC pipe you need for each segment of the new drain line.
- Cut and Assemble: Carefully cut the PVC pipe to the measured lengths using a pipe cutter. Prime and clean the ends of the pipes and fittings before applying PVC cement.
- Connect the pipes: Attach the PVC pipes and fittings, ensuring tight, secure joints.
- Maintain slope: Keep the plumbing level handy to ensure the drain line slopes downwards correctly. It’s all about gravity!
- Conceal the drain line: If necessary, you might need to cut into walls or floors to run the drain line.
- Test the new drain: Before connecting the toilet, run water into the drain line and verify that it flows freely to your main drain.
Reinstall the Toilet and Enjoy the New Drain
1. Install the New Toilet
- Align the toilet: Carefully position the new toilet over the drain line, ensuring proper alignment.
- Secure the toilet: Fasten the toilet to the floor using bolts and nuts.
- Connect the water supply line: Connect the toilet supply line to the valve.
- Connect the drain line: Connect the toilet’s drain line to the new drain line.
2. Test the Plumbing
- Turn on the water supply: Slowly turn the main water supply back on and check for any leaks.
- Flush the toilet: Check for proper drainage and ensure there are no leaks or clogs.
Expert Tips for a Smoother Process
- Vent Installation: Some plumbers recommend installing a vent for the toilet drain line. This helps ensure proper ventilation and reduces the risk of sewer gases.
- Professional Assistance: Complex plumbing situations may require the expertise of a licensed plumber.
