Any special precautions when turning off water to a property?
In addition to what FreeMan stated, if you have an electric water heater you want to turn off the breaker that feeds it. Depending on your plumbing, turning on some hot water faucets to finish some dishes or finish washing up could drain the water heater. If the thermostat for it kicks in and the water level is low, you'll burn up the element in seconds. When you turn your water back on, release any air in the water heater by opening a few faucets. Once your tank in full, turn your power to it back on.
If your tank is gas, it's not so important because your tank don't be damaged like your elements would be but it's still a good idea to shut it off.
