Taboos for Home Toilet Relocation
The taboos for home toilet relocation mainly include the following eight points, which must be strictly followed to ensure safety and proper functionality:
Avoid long-distance relocation Increasing the length of the pipes significantly raises the risk of blockages. Solid substances in the sewage, such as feces and toilet paper, are prone to deposition in long pipes, especially when the slope is insufficient, greatly increasing the probability of blockages. It is recommended that the relocation distance does not exceed 15 centimeters. If long-distance relocation is necessary, the pipes should be re-laid, ensuring a 2-3 centimeter drop per meter of pipe, and avoiding right-angle bends to reduce resistance.
Avoid neglecting the sewage slope The slope is a core condition for sewage discharge. If no slope is set after relocation or a reverse slope is formed (i.e., the end of the pipe is higher than the starting point), sewage will stagnate or even flow backward, causing blockages and foul odors. During construction, a spirit level must be used to check the slope section by section to ensure that sewage can naturally drain by gravity.
Avoid using low-quality relocation devices Low-quality relocation devices, such as PVC pipes with rough inner walls or thin materials, are prone to trapping dirt or breaking, leading to leaks or blockages. Opt for high-quality relocation devices with smooth inner walls and adequate thickness, preferably from well-known brands using PPR or PVC materials, and ensure that the joints are tightly sealed.
Avoid poor drainage and water backflow If the height or angle of the pipes is improperly designed after relocation, water flow obstruction points can form (e.g., sudden narrowing of the pipes or excessive bends), resulting in slow drainage or sewage backflow. Professional calculations are needed to determine the pipe diameter and the number of bends to avoid excessive local resistance.
Avoid poor privacy and inconvenience If the toilet is too close to the door, sink, or other areas after relocation, or if there is a lack of partition design, it can reduce the user's sense of privacy. It is necessary to plan the space layout reasonably, ensuring that the toilet is at least 80 centimeters away from surrounding fixtures and considering adding partitions or screens.
Avoid affecting the neighbors downstairs Relocation construction may damage the original waterproof layer or alter the pipe structure, causing ceiling leakage or poor drainage for the neighbors downstairs. Strict adherence to construction specifications is essential. Communicate with the property management before renovation, avoid damaging public pipes or structural beams, and conduct a closed-water test after construction.
Avoid choosing the wrong type of toilet Siphon toilets rely on the siphon effect for flushing and have higher requirements for pipe slope. If the slope is insufficient after relocation, blockages may occur due to insufficient flushing force. It is recommended to choose a straight-flush toilet, whose flushing method relies more on gravity and is more adaptable to pipe conditions.
Avoid illegal renovation According to the "Measures for the Administration of Interior Decoration of Residential Buildings", it is prohibited to convert rooms without waterproof requirements (such as bedrooms and living rooms) or balconies into bathrooms. Illegal renovation may lead to legal disputes, and balconies and other areas usually do not have pre-installed drainage pipes. Forced renovation can result in long-term leakage and structural safety hazards.
Summary: Toilet relocation should follow the principle of "avoid relocation if possible". If relocation is necessary, strict control must be exercised in four aspects: distance, slope, materials, and toilet type, and construction must comply with regulations to avoid affecting the rights and interests of oneself and others.
