There is a German dissertation of the 'Brandenburgische Technische
Universitaet Cottbus' by H. Feurich (7/98) which has the subject
'Untersuchungen zur Wassereinsparung bei der Klosettspuelung und zu
kleineren Rohrweiten bei der hydraulischen Dimensionierung der Zufluss- und
Abwasserleitung' (Sorry, it is only in German). He used toilets from
different companies (Fa. ROTTER, Germany; VILLEROY&BOCH) and different
accessories (Fa. GEBERIT, FRIATEC and Fa. AQUA BUTKE-WERKE, Germany). May
be you can get information of these companies.
