🚿 Compact power, zero odour – the smart trap your basin deserves!
The McAlpine WHB-1 is a compact 1¼" self-closing basin waste trap designed to save space and prevent odours with its innovative membrane valve. Its 62mm height fits neatly under basins, while the self-sealing mechanism blocks sewer gases without needing a water seal, eliminating evaporation issues. The trap also features an integrated air intake for flexible plumbing layouts and can be easily cleaned without full disassembly, making it a hygienic, durable, and maintenance-friendly solution for cloakrooms and basins.
