Water Leakage in the Upstairs Toilet of a Mobile Board House
Water leakage in the upstairs toilet of a mobile board house may be caused by damage to the waterproof layer, pipe leakage, unsealed tile gaps, or clogged floor drains, requiring targeted detection and handling.
Damage to the Waterproof Layer
If the waterproof layer is damaged, the leakage is usually intermittent, severe when water usage is concentrated, and only leaves leakage marks when water usage is low. During detection, this characteristic can be used to determine whether it is leakage from the waterproof layer. If treatment can be carried out on the upstairs floor, special waterproof glue that does not require breaking tiles can be used to seal the tile gaps, with a focus on checking and sealing the gaps around the pipe roots. If the upstairs does not cooperate with treatment, high-pressure grouting for water leakage blocking can be carried out on the downstairs ceiling. Epoxy resin glue is used, and after drilling holes in the bathroom ceiling, it is injected with a high-pressure grouting machine. However, this method may cause the upstairs floor tiles to bulge.
Pipe Leakage
Pipe leakage requires special attention for inspection because water from a damaged waterproof layer may flow down along the pipes, and it is necessary to determine whether it is leakage from the bathroom sewer pipes or the waterproof layer. Detection methods include visual inspection to observe whether there are obvious cracks, damage, or damp marks on the bathroom floor and walls; water pipe testing, which involves closing all faucets and water-using equipment and then observing the water meter. If the water meter continues to turn, it indicates water pipe leakage; dye testing, which involves pouring dye into suspicious areas on the floor or walls and observing whether there is dyed water seeping downstairs; and infrared thermal imaging, which can quickly detect hidden water pipe leakage and water seepage points inside the walls. If it is determined to be pipe leakage, a professional plumber is required to repair or replace the pipes, ensuring that all joints and connections are properly sealed.
Unsealed Tile Gaps
If the tile gaps are unsealed, waterproof tile glue can be used to fill the tile gaps to enhance the waterproof performance and prevent water from seeping into the downstairs area through the gaps.
Clogged Floor Drain
If the floor drain is clogged, it is necessary to clean the floor drain to ensure smooth drainage. You can also consider replacing it with a more efficient floor drain to prevent future clogging.
After completing the water leakage repair work, a 24-hour closed-water test should be carried out. Fill the bathroom with water and observe whether there is any leakage. In addition, it is recommended that the upstairs owner regularly inspect the bathroom facilities to prevent similar problems from occurring again.
