Domestic Water Supply System works well and fulfills its service. Point deduction comes from the processing of which is not carried out completely in stainless steel (flange from the accumulator and div. Small parts) which are, however, in contact with water. Also I noticed that the filter in the seal has a lot of game, and thus only partially as a filter is used. I would take the next time more money into their own hands and look at that product under the above points in more detail.
