There is disclosed herein a dialysis machine: (a) to which a negative pressure dialyzer can be connected; and (b) which can be operated so as to drain the dialysis solution from the dialyzer through the lower of the dialysis solution inlet and outlet ports. This apparatus and method permit a dialyzer to be drained of dialysis solution at the end of the dialysis treatment session in such a manner as to prevent spillage and leakage associated with the removal of the dialyzer from the machine.
