A tap assembly mounted on the upper-chamber upper wall has a riser tube projecting through the partition center part into a lower region of the lower chamber. An upper protective ring is fitted to the upper part and to the valve assembly and a lower protective ring is fitted to the lower part. The rings and side walls have the same diameters.
