Can Toilet Drainage Be Moved?

Toilet drainage can be moved, but it requires careful operation, and the relocation methods vary for different facilities.

Toilet Relocation

The relocation of a toilet should be planned based on the distance. For short distances (within 15 centimeters), a specialized relocation device can be used. It is advisable to choose products with a streamlined design and no right-angle bends to reduce drainage resistance. If the relocation distance exceeds 40 centimeters, two options should be considered: one is to raise the floor by about 20 centimeters and relay the pipes, ensuring a reasonable slope; the other is to negotiate with the downstairs neighbor to connect a new pipe from their ceiling directly to the main pipe. Although the latter option involves complex construction, it offers more reliable drainage.

Sink Renovation

Renovating the sink drainage is relatively simple. Converting from floor drainage to wall drainage is a common approach, which not only saves floor space but also increases storage areas. During renovation, pipes should be embedded in the wall, and an anti-odor trap should be installed to prevent odor backflow. Additionally, the slope of the pipes should be maintained (usually not less than 2%) to ensure smooth drainage.

Floor Drain Relocation

Relocating a floor drain requires cutting a groove in the floor, but it is important to note that adding a new floor drain can easily lead to poor drainage. It is recommended to prioritize adjusting the position of the existing floor drain. If a new one must be added, ensure a reasonable pipe slope and avoid sharing pipes with other drainage facilities to reduce the risk of blockage.

Construction Precautions

1. Professional Operation: All relocation work should be carried out by professional technicians to avoid leaks or blockages caused by improper operation.
2. Material Selection: Pipes should preferably be 110mm standard round pipes to reduce drainage resistance; avoid using flat pipes or 90° right-angle bends to lower the risk of blockage.
3. Joint Treatment: The pipe joints should be sanded clean and coated with waterproof glue to ensure tightness.
4. Water Closure Test: After construction, a two-day water closure test should be conducted to check for leaks.

Relocating toilet drainage involves pipe layout, slope design, and waterproofing treatment. It is necessary to comprehensively consider actual needs and construction conditions to ensure the long-term stable operation of the drainage system.
