1 He is fit to do it.
2 He is fitting to do it.
3 The water is fit for drinking.
4 The water is fitting for drinking.
I can't pin point why it feels that 2 and 4 are wrong. If I think rationally, they must make sense. Are they wrong and why?

Don't be confused by the fact that the word 'fit' can also be a verb - as adjectives, 'fit' and 'fitting' are completely different words with different uses.
'Appropriateness' means suitability in the context, meaning something fitting/appropriate in one context may not be in another. 'Fit' is not usually contextual (unless you qualify it by saying fit for purpose); for example, a person who is physically fit doesn't become unfit in different settings.
Examples:
If a source of water was declared "fit" to drink, it is safe and suitable to drink. That would be universally true - the water would be unsafe in any context or setting.
We would say that a piece of music was "fitting" if it was appropriate to the setting. Most people would consider "Disco Inferno" to be inappropriate at a cremation as grieving relatives would not want to hear the chorus of burn baby burn as the coffin goes into the incinerator; yet the same song would be wholly appropriate at a disco party. Context makes it fitting.
The use of fitting as an adjective is described in this dictionary.
fitting. adjective, formal
right for a particular situation or occasion. SYN: appropriate
- I thought the memorial was a fitting tribute to the president.
- a fitting end to what was a memorable trip
it is only fitting (that)
- It is only fitting that Simon should propose the first toast tonight.
It seems unlikely that one would use fitting to say water is, or is not, appropriate, but this form is not impossible.
One could say, "Water is not fitting as an alternative to communion wine."
More likely one would say "This water is not fit to drink." Implying it is unpleasant or dangerous to drink .
There are two reasons that 2 and 4 feel wrong. One is that "fitting" really means "appropriate in a cultural sense". A typical use might be:
Her speech was a fitting tribute to her father.
The other reason is that "fitting" is a word that is just somewhat restricted in its natural use. It is relatively rare to see it used as a predicative adjective when not applied to the dummy subject "it". So
It is fitting to drink Champagne at a celebration.
is very normal, but
Champagne is fitting for celebrations.
sounds a little weird to my ear. Not ungrammatical, but not a phrasing you'd see often. On the other hand,
Champagne is a fitting beverage for celebrations.
is natural. The difference is that, before, "fitting" is predicative - it is part of the predicate of the sentence, directly applying to the subject. But, in the last example, "fitting" modifies "beverage", and it seems natural.
Only one of those examples works: 3 'The water is fit for drinking…' and there,'The water is fit to drink' would be more usual.
4 'The water is fitting for drinking' could never work. 'It is/could be fitting to drink the water' has a wholly different meaning.
1 'He is fit to do it…' should rather be, 'He is fit for it…'
Rather differently, 2 'He is fitting to do it…' should be, 'He is fitted to do it…' or, very differently, 'It is/could be fitting for him to do it…'
