To make sure your water is off when you go away, follow these guidelines
Locate the main water valve: Find the main water valve for your property, which is typically located near the water meter or in the basement.
Turn the valve clockwise until it stops to shut off the water supply to your home. This will prevent any water from flowing into your home while you are away.
Turn off individual water valves for appliances such as washing machines, dishwashers, and toilets. This will prevent any water from entering these appliances while you are away.
Turn on all the faucets in your home, including the outdoor faucets, and let them run until the water stops flowing. This will help drain the water lines and prevent any water from sitting in the pipes and potentially causing damage.
Turn off the water heater, which will prevent it from heating water that is not being used and potentially causing damage.
Consider installing a water alarm that can detect leaks and alert you to any potential water damage while you are away.
