## Summary description

Low-profile washbasin trap McAlpine WHB1-32 features a self-closing silicone membrane with a 25 mm opening. Designed for installation beneath washbasins to prevent odours while allowing water drainage, it suits compact or shallow cabinet spaces. Construction provides a reliable seal and straightforward connection to standard waste piping for domestic and commercial bathrooms.

## Long description

The McAlpine WHB1-32 low-profile washbasin trap is designed to fit beneath washbasins where space is limited. It features a self-closing silicone membrane with a 25 mm opening that allows water to drain while maintaining an effective seal against sewer gases. The compact shape and low height make it suitable for installation in shallow cupboards or wall-hung basins, and it connects directly to standard 32 mm waste piping for domestic and commercial bathroom use.
Advantages
This trap offers a reliable odour barrier through its self-closing silicone membrane, reducing the risk of unpleasant smells without needing a traditional water seal. The low-profile design saves space under the basin and simplifies installation in tight cavities. Constructed for straightforward connection to standard waste systems, it provides durable performance with minimal maintenance and a hygienic silicone surface that is easy to clean.
Suitable for
Compact washbasins in small bathrooms or cloakrooms
Wall-hung basins with shallow installation depth
Under-sink cavities in fitted furniture where height is restricted
Commercial washrooms where low maintenance and odour control are required
Key specifications
Type: low-profile washbasin trap with self-closing membrane
Membrane material: silicone
Membrane opening diameter: 25 mm
Connection size: compatible with 32 mm waste piping
Height: reduced/low-profile design for shallow installations
Application: domestic and commercial bathroom washbasins
How to use
Install the trap directly to the basin waste outlet and connect it to the existing 32 mm waste pipe, following standard plumbing practice and ensuring secure joints to prevent leaks. The silicone membrane remains closed when the basin is not in use, opening under water flow to allow drainage and then returning to a sealed position. Periodically inspect the membrane for debris and clean with a mild detergent if necessary to maintain reliable sealing.
Usage recommendations
For reliable performance, ensure the trap is fitted in a horizontal alignment without undue stress on joints and avoid using aggressive chemical cleaners that can degrade silicone. If installed in a commercial setting, schedule periodic checks to remove limescale or deposits and confirm the membrane closes fully between uses.
