Not sure if this info will be useful for anyone but the Speed Queen folks gave me this data. With the rotary switch set at the mini water level position the unit will fill with 12 gallons of water. At the small water setting it will fill with 14 gallons of water. At the mid size load setting it uses 17 gallon. at the largest load size it uses 19.5 gallon. I have not been able to check this . This does not include the water used during the rinse part of the cycle.
