What uses more water, dishwater or washing by hand?

Studies show washing by hand uses far more water, but I'd like to know how those dishes were being washed by hand. I've always done my by hand and have developed water thrifty methods. For example, letting water run is a no-no. Use a dish pan for soapy water or only fill the sink with an inch of soapy water. If you have a spray attachment you can spray rinse at one time instead of individual items.What uses more water, dishwater or washing by hand?
Like most, I would have said a dishwasher used more water. However. . . . just in the last couple of weeks, was watching ';Living With Ed'; (Ed Begley, Jr.) on HGTV. He commented on the studies about hand washing dishes using more water (he was surprised too).
If you fill the sink then turn the water off, only turning it back on to rinse, hand washing will use less water. If you leave the water running the whole time, a dishwasher may use less (depending on the amount of dishes)
definitely a dishwasher, i have done a-lot of washing and definitly the dishwasher, try it, one month use only dishwasher, the next use ony handwash, see the diff. in price
probably a dishwasher
