How much water is too much water?

I easily drink 3 Litres a day and usually want more but I'm worried this is too much.

I don't eat much salt, I rarely have coffee or dehydrated foods and eat so much fresh fruit and veg, so why am I still thirsty?

I used to have kidney problems as a child. Perhaps I should go and get a check-up. Mmm, I love cucumber and celery. Sometime I do eat juicy fruits instead of having a glass of water.
