Bottle trap Franke Grey Line for 2-compartment sink — space-saving design

The Franke Grey Line bottle trap for 2-compartment sinks is a compact plumbing component engineered for installation beneath dual-bowl kitchen sinks. It provides wastewater drainage and an effective water seal to prevent sewer odors from entering the cabinet. The unit is designed for space-saving under-sink arrangements and fits standard drainage connections commonly used in residential kitchens.

Advantages

This bottle trap combines a compact footprint with reliable sealing performance, allowing more usable storage space in the sink cabinet. Its Grey Line finish integrates with modern kitchen plumbing aesthetic standards and the component is compatible with common pipe diameters and fittings. The design simplifies installation and maintenance with removable parts for cleaning and de-scaling without dismantling the whole drainage system.

Suitable for

• Two-compartment kitchen sinks in residential settings
• Kitchens with limited under-sink storage where compact plumbing is required
• Renovation projects replacing larger or damaged bottle traps
• Installations that require straightforward access for cleaning and maintenance

Key specifications

• Configuration: bottle trap for two-compartment (dual-bowl) sinks
• Design: space-saving, compact under-sink profile
• Material and finish: corrosion-resistant components with Grey Line appearance
• Compatibility: fits standard household sink drain connections and common pipe diameters
• Maintenance: removable trap body for easy cleaning and debris removal

How to use

Install the bottle trap by connecting the inlet arms to each sink waste outlet and the outlet to the existing household waste pipe, ensuring seals and compression fittings are seated correctly. After tightening connections, fill the sink and check for leaks around joints. Periodically inspect the trap for accumulated debris and remove the trap body to clean the interior when flow slows or odors are detected. Reassemble and retest for leaks after maintenance.

Usage recommendations

Use compatible sealing rings and tighten fittings to the manufacturer’s recommended torque to avoid leaks. Avoid disposing of large food solids and grease directly into the sink waste to reduce the need for frequent cleaning. If installing in a confined cabinet, measure available clearance and pipe alignment before fitting to ensure unobstructed access for future maintenance.
