Troubleshooting
Water draining slowly
Remove the grille and check the internal siphon trap for hair, lint, or debris buildup.
Presence of odors
Ensure the siphon trap has water in it; if the area is rarely used, water may have evaporated. Also, check that the unit is seated firmly in the floor.
Difficult to rotate drain outlet
Ensure there is no excess mortar or construction debris blocking the rotation mechanism at the base.
Pros and Cons
Pros
- Effective odor prevention via built-in siphon
- Easy access for cleaning and inspection
- Flexible 360-degree drain orientation
- Adjustable height accommodates different floor depths
Cons
- Restricted to 50 mm diameter piping
- Fixed 150x150 mm frame size may not fit all existing floor voids
- Requires proper sealing during installation to prevent sub-floor leakage
Setup, Compatibility & Care
For optimal performance, ensure the unit is installed level with the finished floor surface. The adjustable height range of 70-80 mm should be set using mortar or an appropriate flooring adhesive to ensure the frame is flush. The unit is designed exclusively for 50 mm diameter pipes; do not attempt to force the connection onto larger or smaller pipe diameters. For maintenance, simply lift the central grille once every few months to rinse away sediment and verify the siphon trap is clear of debris to maintain the integrity of the odor seal.
