Relocating Toilet Position

The position of a toilet can be relocated using three methods: the toilet position shifter method, the raised floor method, and the installation of a horizontal sewage pipe. Here are the specific operations and precautions for each method:

1. Toilet Position Shifter Method
This method is suitable for small-scale, short-distance relocations, typically ranging from 10 to 30 centimeters, with a maximum limit of 40 centimeters. The core principle involves connecting the original drain outlet to a flat-pipe position shifter at the new location to achieve minor adjustments to the toilet's position. When operating, prioritize using a flat-pipe-specific position shifter, inserting the small-diameter end into the original floor drain interface, ensuring a tight and leak-free connection; the ground portion should be laid with flat pipes, first cutting off the end of the original pipe, then inserting and securing the position shifter, keeping the pipe body level; subsequently, measure the center-to-wall distance of the toilet (i.e., the distance from the center of the drain outlet to the wall) and the length of the horizontal pipe, using PVC glue to bond the components, ensuring a sealed interface; finally, clear any construction debris remaining in the pipe and reserve a slope of 1%-3% when laying the ground to prevent sewage backflow. Precautions: The position shifter will alter the drainage path, potentially reducing flushing efficiency and increasing the risk of blockages. It is recommended to use a large-diameter toilet or a pressurized flushing device, and avoid pouring debris into the pipe.

2. Raised Floor Method
This method involves constructing a raised platform of a certain height (commonly 180 millimeters, adjusted according to the drainage slope) to conceal the horizontal sewage pipe, providing a new installation base for the toilet. During construction, first determine the new toilet position, then construct a brick or concrete platform along the wall, reserving space inside for the installation of the horizontal sewage pipe; the platform surface should be waterproofed and tiled, ensuring a smooth transition with the surrounding floor; the sewage pipe should be laid with a slope of 1%-3%, connecting to the main drainage stack at the end, and sealed with rubber gaskets or cement mortar at the interface. Advantages: It can achieve larger-distance relocations (exceeding 40 centimeters) and provides a more direct drainage path; Limitations: It requires sacrificing some floor height, may affect the aesthetic appeal of the space, and has a longer construction period.

3. Installation of Horizontal Sewage Pipe
This method involves laying a new horizontal sewage pipe beneath the floor slab to redirect the toilet's drain outlet to the main drainage stack at the new location. When operating, first determine the relative position of the new toilet to the main drainage stack, then cut a groove beneath the floor slab to lay PVC sewage pipes, which should be set with a slope according to regulations (usually 1%-3%); at the connection between the horizontal pipe and the stack, install a straight-through tee or a 45-degree elbow to avoid drainage blockages caused by right-angle connections; after laying the pipes, conduct a closed-water test to check for leaks, then backfill the groove and restore the floor slab surface. Applicable Scenarios: Same-floor drainage systems or buildings with conditions for construction beneath the floor slab; Precautions: Coordinate with property management or neighbors to avoid damaging the ceiling of the downstairs occupants, and note that construction costs are relatively high.
