Washbasin siphon GEBERIT model for small spaces d40 white

GEBERIT washbasin siphon model for small spaces d40 in white is a compact plumbing trap designed to provide reliable odor sealing and wastewater drainage for bathroom washbasins where under-sink clearance is limited. The siphon connects to standard 40 mm outlet pipes and is shaped to fit tight installations while allowing access for routine maintenance and cleaning.

Advantages

The compact geometry of this siphon minimizes required space beneath the washbasin while maintaining a secure water seal to prevent sewer gases from entering the room. Its white finish integrates with light-coloured sanitary ceramics and conceals minor dirt or wear. The product is designed for straightforward connection to common waste pipes and supports disassembly for cleaning without specialized tools.

Suitable for

• Small bathrooms and powder rooms with limited under-sink space
• Wall-hung or pedestal washbasins where a low-profile trap is required
• Renovation projects replacing bulky or damaged siphons
• Installations using 40 mm outlet pipe systems

Key specifications

• Outlet diameter: 40 mm (d40)
• Colour: white finish
• Function: water trap (odor barrier) and wastewater drainage
• Installation type: compact/low-profile siphon for under-sink use
• Maintenance: removable components for cleaning access

How to use

Connect the siphon to the washbasin outlet and align the outlet collar with the 40 mm waste pipe, ensuring secure sealing with the provided seals or compatible compression fittings. Tighten connections by hand or with minimal tool torque to avoid damaging plastic threads. Fill the basin and check for leaks at joints; disassemble the removable section if obstruction or odour issues occur and clean internal passages before reassembling.

Usage recommendations

For reliable performance, install the siphon in accordance with local plumbing codes and the washbasin manufacturer’s instructions. Avoid excessive mechanical stress on plastic connections during installation, and periodically inspect the trap for sediment buildup. Use mild cleaning agents and remove blockages promptly to maintain the water seal and drainage capacity.
