 A first possibility to defend the thesis that Water is non-transmissive is to argue that Water instantiates the disjunctive template (considered in Sect. 3.2) (cf. Wright 2000, 2003 and 2011). If Water is non-transmissive, s could acquire a justification for, or knowledge of, P9 and P10 only if s were in possession of an independent justification for, or knowledge of, Q9. (And to avoid the absurd result that McKinsey recoils from, this independent justification for Q9 should presumably be empirical.) If this diagnosis is correct, one need not deny P9 or P10 to block the intuitively false consequence that s could acquire knowledge of the empirical proposition Q9 in virtue of only non-empirical knowledge.
