Details
Standard shallow traps often struggle to clear water quickly, causing annoying pooling around your feet. Consequently, water backs up in your tray, risking leaks along your enclosure’s silicone lines. Furthermore, if a cheap universal trap cracks inside a hidden floor void, it leads to slow tracking leaks. As a result, this hidden dampness rots structural joists and ruins downstairs plasterboard ceilings.
Fortunately, installing this authentic McAlpine chrome shower trap completely eliminates these drainage and leak worries. Specifically, its precision-engineered internal channel dumps a swift 50 litres of water per minute down the drain. Additionally, the premium polypropylene body resists harsh cleaning chemicals and thermal cracking. Therefore, you get an ultra-reliable, high-flow, and completely watertight installation that keeps your tray clear.
