Question: does a dishwasher use more water than washing up by hand in the sink?
Answer: This may appear impossible since it seems like dishwashers are constantly spraying water, but a newer one does use less water than hand washing. Getting them clean in the sink can use up to 27 gallons of water per load. ... In fact, an Energy Star certified dishwasher can save almost 5,000 gallons of water per year.
