Home water usage breakdown charts on the Internet vary a little bit as to the exact percentage each function uses. Most of them put it in this order:
- Toilets use the most, around 26%
- Laundry, about 22%
- Showers come in third at 16% to 18%
- Cooking and drinking use about 9% to 15%
- Dishwashers around 1 to 2%.
The rest is accounted for by leaks and faucet uses like washing hands and face, brushing teeth, etc. Leaks are more common than I thought. All the charts included leaks. To find out whether you are paying for any leaks, turn all the water off and go look at the meter. If the reading changes, there’s a leak. For wells, if the pump kicks on when you aren’t using water, there’s a leak.
