This Kit includes 19 pieces to directly plumb-in any machine with an Ulka vibrating pump that has a barbed-style inlet (as does the current version). The incoming water side starts with a 3/8 MALE BSP, so you will need to determine what you need to connect to your existing water supply, and we do have a variety of fittings and valves that will fit most applications (sold separately, see here for options). Please review Stefano's You Tube installation video here. REQUIRED: You must have water pressure below 4 bar (70PSI) or a water pressure regulator must be installed (available separately). NOTE: There is a risk of water damage whenever directly plumbing a machine. We are not responsible for any damage or issues caused by or related to installing this kit, and we strongly recommend a “leak alarm” as well.
