I had the exact same situation in a village house I rented about two years ago. I had the top floor and the LL owned all three floors. A leak, not our fault, was causing water to run from our shower into the downstairs bathroom. The LL did repairs and we lost hot water to our kitchen. My lease was like kimy's. I argued the point and the ll reconnected the hot water supply to the kitchen. My argument was that we had hot water when we signed.
