The McAlpine WM11V is a type of 'P' trap plumbing fitting designed for use with domestic appliances such as washing machines, dishwashers, and sinks. It features an adjustable inlet with twin swivel connections that allow for flexible installation and a water seal to prevent sewer gas from entering the building. The 75mm water seal helps to prevent odours and bacteria from entering the living space by blocking the drainpipe. The adjustable inlet allows for easy installation and the twin swivel connections make it easier to attach to different discharge pipes. The anti-syphon feature, also known as a Silentrap, prevents water from being siphoned out of the trap, which can cause an unpleasant gurgling noise and the loss of the water seal. The 'P' trap design helps to prevent blockages by trapping debris before it can enter the drainpipe. The 1½" multifit outlet is compatible with a range of waste pipes and the swivel connections make it easier to connect to different appliances. Overall, the McAlpine WM11V is a versatile and reliable plumbing fitting that is designed to meet the demands of modern domestic appliances.
