Movement of Toilet Drain Pipes
The toilet drain pipe can be moved, but an appropriate plan must be selected and careful operation carried out according to the specific situation.
Short-distance relocation (within 40 centimeters) If the relocation distance is short, it is recommended to use a dedicated flat or round pipe relocator. During installation, a slope of 1%-2% should be maintained to ensure the smooth discharge of sewage, while reducing the number of elbows to lower the risk of blockage. This plan is suitable for scenarios with limited space or local adjustments, with relatively simple operation and low cost.
Medium-distance relocation (no more than 3 meters) If the original drain outlet is built into the wall and the new position is relatively close to the original one (generally no more than 3 meters), a toilet relocator (offsetter, sewage relocator) can be used to change the position of the drain outlet. Note that the greater the relocation distance, the higher the slope requirement. Before installation, careful measurement is required to ensure tight pipe connections and prevent leakage. This plan is suitable for local renovations but may affect drainage efficiency.
Long-distance relocation or large-diameter pipes If the relocation distance is large or large-diameter pipes are required, the floor can be raised by 20 centimeters to relay the pipes. This plan can completely solve the drainage problem, but it will raise the bathroom floor, affecting the overall aesthetics and user experience, so the pros and cons need to be weighed before making a decision.
Handling of special situations If the original drain outlet is completely sealed and cannot be restored by other means, the front-flush toilet can be changed to a rear-flush toilet, and a new drain pipe can be installed by drilling a hole in the wall. This plan requires damage to the wall structure and may affect the overall stability of the bathroom, so professional personnel must be hired for construction and ensure compliance with building codes.
Other precautions
- Sunken bathrooms can be freely modified, but cast iron pipes need to be clamped tightly with hoop clamps and sealed with sealant to prevent leakage.
- For same-floor drainage, the renovation plan can be decided by yourself, while for inter-floor drainage, approval from the property management and signatures from neighbors are required.
- A 48-hour closed water test must be carried out after construction to ensure no leakage before proceeding with subsequent renovations.
- Wall-mounted toilets are suitable for scenarios with limited space or a pursuit of aesthetics, but installation is complex, requiring the construction of a false wall to hide the water tank and pipes, and professional design and construction are needed.
