There seems to be some discrepancy about switch positions on this 4-way valve. I suspect that comes from Moeller using different suppliers. The one I received has four handle positions: one for each of three inputs plus mine also has an OFF position where no tank is selected. Furthermore, all switch positions have a click function that makes it easy to tell when you have the handle in the correct position for that tank or the off position. The outlet is at the bottom or back depending on how you look at it; in any case, the outlet is in-line with the valve shaft. The one I have has Moeller part number 33304-10 and was made by the Anderson Brass Co. The valve does seem to be well made and has a quality feel that gives me confidence that it will last a long time.
