The McAlpine STW1-M is a compact shower trap designed for use in small or shallow shower trays. It has a water seal of 19mm and a universal outlet, which makes it compatible with a wide range of plumbing configurations. The trap is designed to prevent unpleasant odors and gases from entering the bathroom through the waste pipe. It features a resealing mechanism that ensures the water seal is maintained even if the trap dries out or the water in the trap evaporates. This prevents foul smells from entering the bathroom and also prevents the build-up of harmful gases such as methane and carbon monoxide. The trap is easy to install and comes with a removable trap body, making it easy to clean and maintain. The chrome finish on the plastic components gives it a clean and polished look, which is suitable for modern bathrooms. Overall, the McAlpine STW1-M is a reliable and effective option for shower installations that require a compact trap to fit in small or shallow shower trays. Its resealing mechanism and universal outlet make it suitable for various plumbing configurations. Flanges available in White or Chrome Plated Plastic, or Chrome Plated Brass Suitable for shower trays with a 50mm waste hole 19mm Water Seal 1.5" BSP Thread 1.5" Universal Outlet
