Check the meter tap at the boundary of your property and make sure that it's fully on. A meter tap, which is usually next to the water meter, controls the water supply to your property. You can turn it on and off, but can't connect a hose to it or use it to fill a bucket. It may look like a standard tap or a lever. Turn it in the direction of the arrow till you feel resistance. Use a spanner if you need to, but don't force it. The tap won't turn if it's fully on. Find out about your meter.
