Catalysis of the hydrolysis of a pyrophosphate bond between two phosphate groups, leaving one phosphate on each of the two fragments. Catalysis of the reaction: guanosine 5'-triphosphate,3'-diphosphate + H2O = guanosine 5'-diphosphate,3'-diphosphate + phosphate. Catalysis of the hydrolysis of any acid anhydride which contains phosphorus.
