The SuperValve is a direct connect inlet. There are two different types of “outlets” on the market. You will either have a “standard” inlet or a “supervalve” inlet in your home. When you have a standard inlet, you would plug in the hose into the wall inlet and then you plug in the “pigtail” end into a 110v receptacle. The Supervalve inlet you just plug in one time. This is also called a one-step process for using your central vacuum system. It is available in White or Almond color. It is sold as a set, the inlet cover and the outlet box.
