About this model

Bathroom U-traps serve to stop foul smells and unhygienic substances (including bacteria and viruses) in the drainage system from entering living areas. Defective or dried U-traps could negate this important function. To ensure they functioned properly, water should be added to the U-traps regularly. Therefore, I designed these boxes for refilling water into the drain outlet without wetting the floor.
