Turn the taps off. In one day a hot dripping tap could fill a bath.
Since I got a new kitchen a couple of years ago and a new bathroom last year (after a fashion), my taps are all pretty good and don't drip - and I never leave them running or anything like that. The only thing that leaks is the shower, but it's more in a "spurting out spare water when the air pressure changes a bit" sort of way, rather than in a "needs fixing" kind of way.
However, I reused the leftover water in my water bottle to water the plants today, rather than just throwing it away, and I will try to do this from now on.
