Everyone knows that the water meter is based on the water pressure. When we turn on the faucet to open the faucet to the maximum, the water meter will turn very fast. When the faucet is opened, the water meter will turn slower. So many poor people will make the taps smaller and save a little money. However, some people will find that if the faucet is loosened at night and let it drip, the water meter will not go.
