Toilet Pipe Movement
The movement of toilet pipes requires selecting an appropriate plan based on the specific type and distance of movement, and strictly adhering to construction specifications to ensure drainage safety and the stability of the building structure.
Toilet Pipe Movement
Short-distance Movement (Generally ≤3 meters, some scenarios ≤15 cm or 10-20 cm) Using a toilet offset flange is a common solution, but note the following:
- Slope Control: After relocation, the pipe should maintain a slope of 1%-2% (a drop of 1-2 cm per meter) to prevent poor drainage or backflow.
- Sealing Treatment: The joints should be sealed with special glue or sealing rings to prevent leaks.
- Waterproofing Requirements: The floor around the offset flange should have a waterproof layer extending at least 30 cm up the wall.
Long-distance Movement
- Raising the Floor: Raising the floor to bury the pipes is suitable for large relocation distances or when large-diameter pipes are needed, but it may affect the aesthetics and usability of the bathroom.
- Re-drilling Holes: Changing a front-discharge toilet to a rear-discharge one and installing new drainage pipes by drilling holes in the wall requires damaging the wall structure, which may affect stability and should be done by professionals.
- Floor Slab Pipe Adjustment: Damaging the floor slab to rearrange drainage pipes and connect directly to the main drainage stack provides stable drainage but is costly, time-consuming, and requires approval from property management or neighbors.
Sink Pipe Movement
Changing to a wall-mounted drainage system can hide the pipes within the wall, improving aesthetics and saving space. However, note the following:
- Filtering and Cleaning: Install a strainer with a filter screen and clean it regularly to prevent clogging.
Floor Drain Pipe Movement
Only small-scale relocation (generally ≤30 cm) is supported, and the “30-5-2” principle should be followed:
- Relocation Distance: No more than 30 cm.
- Slope Requirement: The pipe should maintain a 5% incline.
- Specialized Tools: Use a specialized offset flange with two 45-degree elbows to reduce drainage resistance.
General Precautions
The movement of toilet pipes involves the stability of the drainage system and the safety of the building structure. Be sure to consult a professional plumber or decoration company before construction to ensure the plan is reasonable and feasible. If the floor slab or wall needs to be damaged, obtain approval from property management or neighbors in advance to avoid subsequent disputes.
