Mobile Toilet Pipeline Renovation

The renovation of mobile toilet pipelines requires selecting appropriate methods based on the relocation distance, building structure, and actual needs. The following are common renovation methods and key considerations:

I. Common Renovation Methods

1. Toilet Relocator Suitable for short-distance relocation (generally ≤3 meters), it achieves relocation by connecting the original toilet drain pipe with the pipe at the new location. Key Points: The longer the relocation distance, the higher the required drainage slope (usually ≥2%), otherwise, blockages are likely to occur. Ensure tight pipe connections to prevent leakage.

2. Same-Floor Drainage Renovation

   • Floor Slab Lowering: If the original bathroom structure has a lowered slab (250-350mm), the toilet and drain outlet can be freely arranged within the lowered slab space, and a slanted tee can be used to connect the pipes to reduce the risk of blockages.
   • Floor Slab Raising: Raise the floor by building a platform (180-200mm), rearrange the drain outlet, and connect it to the main sewage pipe. Suitable Scenarios: Long-distance relocation, but the workload is large, and the floor height needs to be considered.

3. Inter-Floor Drainage Renovation

   • Relocating the Drain Below: Requires negotiation with the downstairs resident to open a hole in their bathroom ceiling to arrange the pipes. Note: Proper waterproofing and trap anti-odor treatment must be carried out to prevent leakage or odor backflow.
   • Wall-Hung Toilet Conversion: Embed the toilet tank in a steel structure, install the toilet on the wall, allowing for a large relocation distance and saving space. Requirements: Professional design of wall bearing capacity and pipe layout is needed, and the installation complexity is high.

4. Raising the Floor to Relocate the Toilet Hide the pipes by raising the floor, suitable for situations with a large relocation distance or the need to use large-diameter pipes (such as 110mm standard round pipes). Disadvantages: It may affect aesthetics and user comfort, so the pros and cons need to be weighed.

5. Opening a New Hole to Relocate the Toilet When the original drain outlet is completely sealed, the front-discharge toilet can be converted to a rear-discharge one, and a new hole can be opened in the wall to install the pipes. Risks: Damaging the wall structure may affect stability, so the building safety needs to be evaluated in advance.

II. Key Considerations

• Compliance: In regular commercial housing, only the household's own branch pipes can be modified, and the main sewage pipe cannot be moved. The scope of renovation needs to be confirmed with the property management in advance.
• Negotiation and Communication: When involving inter-floor renovation, negotiation with the downstairs resident is essential to avoid disputes.
• Pipe Selection: Prioritize the use of 110mm standard round pipes, reduce the use of flat pipes and 90° sharp bends, and ensure that the drainage slope meets the requirements.
• Toilet Adaptation: For units with relocation or double traps, it is recommended to choose a pressure-boosting flushing special toilet (such as the Mite Kirin pressure-boosting flushing toilet) to solve problems such as high drainage resistance and air-blockage water blockage.
• Sealing and Anti-Odor: Ensure tight interface sealing during installation and equip with anti-odor fittings (such as traps and anti-odor floor drains) to eliminate leakage and odor.
