The McAlpine BW1 is a chrome-plated plastic basin waste with a backnut model that features a 60mm flange and a 3½" tail with a plug. This type of basin waste is designed for use in basins or sinks where the waste outlet is located at the bottom of the basin. The 60mm flange is the visible part of the waste that sits on top of the basin, while the 3½" tail connects to the waste outlet. The backnut design means that the waste can be tightened securely in place from underneath the basin, ensuring a leak-free seal. The plug is used to stop water from flowing down the waste outlet, allowing the basin to hold water when needed. It can be removed to allow water to drain away. Overall, the McAlpine BW1 is a durable and reliable choice for a basin waste, suitable for use in both domestic and commercial settings. ・ Available Slotted or Unslotted ・ Available with Black PVC of Chrome Plated Plastic Plug ・ 1¼" BSP ・ 60mm flange ・ 3½" Tail
