Needs a fresh water supply, relatively easy if near a sink, so you can add an isolating tee valve so as to supply the water. The adaptor supplied screws nicely onto a 15 mm isolating at the end of push fit plastic fittings and 15mm supply pipe, this must be supported by several 15 mm pipe clips, so the fittings do not move excessively.Just need to plumb in a simple drain to allow excess water to drain by gravity, ABS drainpipe works well.Cleaning cycle just requires lemon juice or vinegar added prior to use. Spare silicon plugs are for the water reservoir.Better value by far than my previous worktop model. Much more substantial, likely to last much longer.
