Can you answer the question 何を飲みますか？ with 水です。?


It doesn’t seem that natural, as 水です seems to mean “It is water”, rather than
a shorter form of 水を飲みます.




Yes, you can safely say 水です. The implied subject ("it") refer's to "what I
want to drink".

Moreover, in Japanese, it's even perfectly natural to say 私は水です if there is
enough context! See: [Are possessive particles implied in a
conversation?](https://japanese.stackexchange.com/q/44053/5010)
