Details

Installing high-output power showers with standard, low-capacity drainage is a recipe for disaster. Consequently, water flows faster than standard traps can clear it, leading to frustrating pooling, slippery surfaces, and potential overflows. Furthermore, standard side-entry traps often force your pipework into awkward, convoluted bends just to reach the drain point, creating unnecessary flow restriction and strain on your joints. This clunky arrangement often results in slow drainage, frequent blockages, and an increased risk of joint stress that leads to hidden, structural water damage beneath your shower tray.

Fortunately, installing this high-capacity McAlpine vertical shower waste solves these flow-rate and pipe-alignment headaches completely. Specifically, the vertical outlet design provides a direct, gravity-assisted drainage path, while the massive 50 L/min flow rate ensures your shower enclosure stays completely puddle-free, regardless of your water pressure. Additionally, the premium chrome-plated brass slotted top looks fantastic and allows for simple debris removal from above. By streamlining your pipework and maximizing drainage efficiency, you get a reliable, high-performance, and permanently watertight installation.
