Details

Standard, slow-draining shower wastes are an absolute nightmare in modern bathrooms. Consequently, high-pressure booster pumps and large shower heads quickly overwhelm low-capacity traps. Therefore, you face immediate water pooling, flooded enclosures, and slippery bathroom floors. Furthermore, fixed, awkward outlet angles force your pipework into unnatural positions beneath the tray. As a result, tight joist spaces put heavy structural tension on your plumbing lines. Consequently, this clunky setup creates hidden tracking leaks, ruining lower-floor plasterboard and costing thousands in emergency property repairs.

Fortunately, installing this genuine McAlpine shower drain waste solves these slow-drainage and tight-space headaches completely. Specifically, the high-capacity internal trap layout delivers a powerful 26 litre per minute flow rate. Therefore, it clears wastewater rapidly to prevent any pooling inside the tray. Additionally, the included 135-degree adjustable swivel bend easily bypasses frustrating floor joists without putting stress on the joints. The removable 110mm brass flange also allows you to clear out debris directly from above. Consequently, you get a highly reliable, easily maintained, and permanently watertight installation.
