The McAlpine WM11 is a heavy-duty tubular swivel P trap engineered specifically for the simultaneous discharge of multiple domestic appliances. Manufactured from highly resilient white polypropylene, it features a 75mm water seal to effectively prevent foul sewer gases from entering the residential environment. The intelligent configuration incorporates twin 135-degree swivel inlet nozzles, providing exceptional flexibility when connecting discharge hoses from both a washing machine and a dishwasher located within the same immediate under-counter space.

Delivering a substantial flow rate of 63.5L/min, this trap ensures rapid wastewater clearance without the risk of backing up. The adjustable inlet mechanism allows the unit to accommodate complicated spatial constraints, making it an indispensable component for domestic repair, maintenance and improvement works. Furthermore, the 1.5inch multifit compression outlet guarantees a highly secure and watertight connection across a broad spectrum of pipe materials, including modern plastic, traditional copper and historic lead runs.
