For the benefit of the OP: The leakage issue is mainly an installation issue. I had a similar issue with a Godrej A/C. Now, that does not make the Godrej A/C any inferior. The problem was with the slope of the drain pipe. If the slope is not properly maintained, over a period of time, due to excess humidity (during rainy seasons) and dust accumulation if not properly cleaned there could be some clogging. This generally is not an issue if the slope is OK as gravity will take care of draining of the water. In my case, I had to get the slope adjusted to get rid of the drainage issue.
