The McAlpine CA32MINI-CB is a plumbing trap designed to prevent the entry of foul gases from the sewer system into a building. It is a bottle trap, which means it has a curved section that holds water, creating a barrier that prevents the gases from passing through. The trap has a compact design that allows it to fit into tight spaces without compromising on performance. It features a 50mm water seal and a chrome-plated brass construction, which provides durability and resistance to corrosion. The trap also comes with a 12" length of 32mm outside diameter chrome-plated brass waste pipe and wall flange, making it easy to connect to the waste pipe and install on the wall. Overall, the McAlpine CA32MINI-CB is a reliable plumbing trap that is easy to install and provides a secure and leak-free connection between the pipework and the trap. Its compact size and durable construction make it a popular choice for installations where space is limited, and a high-quality, corrosion-resistant trap is required. 32mm European Outlet 50mm Water Seal Adjustable Inlet Includes 12" length of 32mm OD CP Brass Waste Pipe and Wall Flange Supplied with MS4-32SOLVENT fitting to convert to 1.25" UK pipe size McAlpine CA32MINI-CB Chrome Plated Brass Basin Kit with Mini Bottle Trap in Silver
