Every time you run your dishwasher, you use about 25 gallons of water. If you have two sinks, fill one with soapy water and one with rinse water. If you have one sink, gather all the washed dishes in the dish rack and rinse them with an inexpensive spray device. You can do this more efficiently by filling a large bowl with water or putting a stopper in the sink and filling the sink with water. Even the smallest drip from a worn washer can waste 50 or more gallons of water each day.
Larger leaks can waste hundreds of gallons.
Your automatic washer uses 30 to 35 gallons of water in a cycle. That's a lot of water for three T-shirts. A leak in your toilet may be wasting more than 100 gallons of water per day. To check, put a little food coloring in you toilet tank. If, without flushing, the coloring begins to appear in the bowl, you have a leak.
