Moving the Toilet Position by 1 Meter

Moving the toilet position by 1 meter requires caution, as improper operation can easily lead to blockages and is considered a high-risk project. It is recommended not to proceed unless absolutely necessary.

I. Risks and Principles of Relocation

The maximum relocation distance for an ordinary flat-pipe relocator is only 15 centimeters, and a 1-meter relocation far exceeds its limit. Long-distance relocation can result in insufficient slope in the drainage pipe, slowing down the water flow and causing solid waste to deposit and block the pipe, much like using a thin straw to suck up thick eight-treasure porridge, significantly reducing drainage efficiency.

II. Core Preventive Measures

1. Drainage System Assessment

   • For same-floor drainage units, relocation can be done directly, but it is necessary to ensure that there are no structural obstacles in the pipe routing. For interlayer drainage units, it is crucial to check the feasibility of connecting the floor opening position with the main sewage pipe to avoid damaging the building structure.
   • It is mandatory to use a standard 110mm pipe, as a smaller diameter can exacerbate the risk of blockages. The pipe should maintain a slope of 2%-3% (i.e., a drop of 2-3 centimeters per meter), which can be achieved by raising the floor by 20 centimeters.

2. Toilet and Construction Specifications

   • Prioritize single-cylinder direct-flush toilets, which have strong flushing power and a short drainage path, making them more suitable for relocation scenarios than siphon-type toilets. The outlet should be raised by 5-10 centimeters to utilize gravity for accelerating drainage.
   • Wall-mounted toilets are a better solution, as their drainage pipes connect directly to the main riser. However, they require pre-embedding of a steel frame structure, and the flush volume is recommended to be ≥6 liters to ensure sufficient flushing power.

III. Specialized Plan for 1-Meter Relocation

1. Floor Raising Method

   • Raise the floor locally by 20 centimeters, embed a 110mm pipe, and ensure a visible slope. Note that the waterproof layer on the floor should be extended to the raised area to prevent leakage.

2. Wall-Mounted Toilet Plan

   • Although the installation cost is higher, the drainage path is the shortest. During construction, use a laser level to confirm the slope, and prohibit disposing of easily blockable items such as tissue paper and sanitary napkins.

IV. Key Considerations

• Professional Assessment is Essential: A 1-meter relocation involves multiple aspects such as pipe modification, waterproofing, and slope calculation. It must be inspected on-site by a licensed plumber to confirm conditions such as floor load-bearing capacity and the position of the main sewage pipe.
• Daily Usage Restrictions: It is strictly prohibited to pour leftover food, hair, wet wipes, etc., into the toilet, as these items can accelerate pipe blockages.
• Risk Notification: Even with all measures taken, there is still a risk of blockage with a 1-meter relocation. Regular unclogging preparations (such as using pipe unclogging agents every six months) should be made.

Summary: Relocating a toilet by 1 meter is a challenging project that requires comprehensive prevention and control of blockage risks from three aspects: drainage system, toilet selection, and construction specifications. If the unit layout allows, it is recommended to adjust the bathroom layout (such as changing the door direction) instead of relocating the toilet.
