Movement of Toilet Drain Pipes

Toilet drain pipes can be moved, but strict adherence to technical specifications and construction requirements is necessary. The following are specific considerations:

1. Distance Control for Relocation

• Short-distance relocation (≤40 cm): It is recommended to use specialized flat relocators or round pipes, which can reduce space occupation and lower the risk of blockage.
• Long-distance relocation (>40 cm): The floor needs to be raised by 20 cm to relay the pipes, while ensuring that the pipe slope meets the standard. Relocation of the toilet bowl is not recommended to exceed 80 cm, as it may lead to poor drainage, blockage, or unpleasant odors.

2. Slope Design and Construction

• The relocated pipes must have a slope of 1%-2%, meaning a drop of 1-2 cm per meter of pipe, to ensure that sewage can naturally flow towards the main drain.
• The outlet should be appropriately raised to prevent water accumulation or backflow due to insufficient slope. During construction, a level can be used to assist in positioning to ensure a uniform slope.

3. Key Construction Details

• Reduce the number of bends: The more bends in the pipes, the greater the water flow resistance and the higher the risk of blockage. It is recommended to use straight pipes for connections and only use 45-degree bends where necessary.
• Sealing treatment: The joints of the pipes should be sealed with specialized glue or sealing rings to prevent sewage leakage or unpleasant odors. Cast iron pipes should be clamped tightly with straps and coated with sealant.
• Avoid structural damage: When cutting slots in the floor, avoid reinforcing bars to prevent damage to the building's load-bearing structure. If avoidance is not possible, contact professionals to evaluate and reinforce the structure.
• Closed-water test: After construction, a 48-hour closed-water test must be conducted to check for pipe leakage. During the test, all drainage outlets should be sealed, and the water level should be no less than 2 cm.

4. Handling Special House Types

• Sunken bathrooms: The position of the drain pipes can be freely adjusted, but attention should be paid to pipe fixation and waterproofing.
• Same-floor drainage: Homeowners can decide on the relocation plan themselves, but it must comply with building codes.
• Inter-floor drainage: Written consent from the property management and signatures from neighbors downstairs must be obtained to avoid disputes later.

5. Tool Selection Recommendations
There are various toilet relocators available on the market, such as UPVC flat drain relocators and PVC drain pipe relocators. When selecting, consider the relocation distance, pipe material, and budget comprehensively, prioritizing products that are corrosion-resistant and have good sealing properties.
