I have looked up
John 3:5 in two different Greek interlinear NT's.
The Emphatic Diaglott says:
ex hudatos kai pneumatos
and The Apostolic Polyglot also says:
ex hudatos kai pneumatos
So both hudatos (water) and pneumatos (Spirit) have the conjunctive Kai (and) but neither have the article "the" so Granville Sharp's rule would not apply here. Pneumatos (Spirit) is not a further definition of hudatos (water) but a separate entity.
