Details

Standard low-profile traps often choke under modern high-pressure systems, causing incredibly annoying pooling water around your ankles. Consequently, your shower enclosure fills up fast, risking messy floor overflows. Furthermore, generic traps with weak seals often slowly leak into floor voids over time. As a result, this hidden moisture rots timber joists and ruins downstairs ceilings, causing thousands in structural damage.

Fortunately, installing this authentic McAlpine shower tray trap solves these flow and leak anxieties completely. Specifically, its deep-body design generates a massive 54 L/min flow rate to clear water instantly. Additionally, the premium British-engineered threads and Multifit compression elbow ensure a permanently watertight mechanical joint. Therefore, you get an incredibly reliable, high-performance, and completely leak-free drainage installation.
