Mobile Toilet Drainage Pipe Drawing Translation

Currently, we cannot directly provide the drawing of the drainage pipes for mobile toilets, but we can offer methods and precautions for relocating the drainage pipes of toilet bowls in restrooms for reference. The specific plan needs to be customized by professionals according to the on-site situation.

Methods for Relocating Toilet Drainage Pipes

1. Inter-floor Toilet Relocation
   Suitable for short-distance relocation (generally within 40 centimeters), achieved by installing a relocation device. Note that the height of the flat pipe of the relocation device may cause the floor to be raised, affecting the ceiling height or subsequent decoration. This method is simple to operate, but the relocation distance is limited, and insufficient slope of the flat pipe may lead to poor drainage.

2. Wall-mounted Toilet Relocation
   By re-laying pipes inside the wall, long-distance relocation can be achieved. The water tank of a wall-mounted toilet is hidden inside the wall, making the appearance more aesthetically pleasing, and the hidden pipes are less likely to get clogged. However, the position of the water tank needs to be planned in advance, ensuring that the height of the water tank from the floor is ≥ 220mm to guarantee sufficient flushing force.

3. Raised Floor Relocation
   By building a new platform to create a slope, the drainage requirements for long-distance relocation can be met. This method is suitable for same-floor drainage or sunken restrooms, but it will significantly increase the floor height, potentially affecting space utilization. Attention should be paid to the slope design of the platform to avoid water accumulation.

4. Other Solutions

   • Sunken Restroom Renovation: Utilize the sunken space of the restroom to re-lay pipes without raising the floor, but issues of waterproofing and backfilling need to be addressed.
   • Oval Flat Pipe Relocation Device: Compared with traditional flat pipes, the oval design can reduce the height of the floor raise, but an appropriate model needs to be selected according to the drainage method (same-floor/inter-floor).

Precautions

• Installation Timing: The relocation device should be installed before tiling to avoid damaging the floor structure later.
• Slope Control: The greater the slope of the pipes, the smoother the drainage and the less the odor. However, excessive slope may affect the flatness of the floor, so a balance needs to be struck in the design.
• Waterproofing Treatment: Waterproofing should be applied at least twice. For sunken restrooms, it should be treated before backfilling and before tiling to prevent leakage.
• Detail Handling: After relocating the flat pipe, a "notch" should be made on the threshold stone to prevent water from flowing back. The height of the water tank of a wall-mounted toilet should strictly comply with the standard to avoid weak flushing.

Suggestions for Obtaining Drawings

If specific drawings are required, it is recommended to contact professional plumbers or designers to customize a plan according to the on-site drainage method (same-floor drainage or inter-floor drainage), relocation distance, and spatial conditions. Professionals can ensure that the pipe layout complies with regulations and is practical through on-site measurement and calculation.
