The McAlpine AA10W is a basin trap with an adjustable inlet and a water seal of 75mm. It has a 1¼" multifit outlet, which means it can fit a range of waste pipes with different diameters. Basin traps are an essential component of any plumbing system, as they prevent unpleasant odors and gases from entering the building from the sewer. The water seal acts as a barrier that stops the gases from passing through the trap and into the room. The adjustable inlet of the McAlpine AA10W makes it easy to connect to different types of waste pipes, including those with different angles and offsets. This flexibility is essential in situations where the waste pipe is not in the ideal position for a standard trap. The McAlpine AA10W also features a removable cleaning eye, which makes it easy to clean the trap if it becomes clogged. This is an important feature, as clogs can cause water to back up and overflow from the sink or basin. Overall, the McAlpine AA10W is a reliable and versatile basin trap that is suitable for a wide range of plumbing applications. ・ 75mm Water Seal ・ 1¼" Multifit Compression Outlet suits all plastic, copper and lead pipe ・ Adjustable Inlet makes trap suitable for all domestic repair, maintenance and improvement work ・ Manufactured in polypropylene ・ Complete with 60mm &Oslash Polished Stainless Steel Waste Flange, Centre Pin fixing and dry jointing Washers, Plug, CP Chain and Stay
