Details

High-performance power showers and booster pumps are an absolute nightmare for standard drainage systems. Consequently, standard traps simply cannot cope with the sheer volume of water, leaving you standing in a frustrating, deep pool of dirty suds during every shower. Furthermore, slow drainage causes immediate basin flooding, risking overflows onto your bathroom floorboards. As a result, water pooling places continuous pressure on the tray’s silicone seals. Consequently, this inadequate setup leads to hidden tracking leaks, rot inside your structural timbers, and incredibly expensive ceiling damage to the rooms below.

Fortunately, installing this high-capacity McAlpine fast flow shower waste trap eliminates slow-drainage and flooding headaches completely. Specifically, the advanced internal design handles a massive 42 litres of water per minute, aggressively clearing waste flow to keep your tray completely clear and puddle-free. Additionally, the included 135-degree adjustable swivel bend easily maneuvers around tricky floor joists to guarantee a stress-free, secure alignment. The removable 110mm brass flange also allows you to clear hair and debris directly from above in seconds. Consequently, you get a highly dependable, maximum-flow, and permanently watertight installation.
