The wash I have has 5 bays of self serve equipment, made by Ginsan.The stinking ba$tards that put this in, can you say Barry Boyd and Mark Zeledick, really screwed the then owner. They took out a perfectly good operating, and less than 2 years old, Stack pump stand by Magic Wand. That system took up a little less than half of the floor space than this thing does. Floor space is coveted in most equipment rooms. So why do some keep making this in single stand per bay configuration? Ginsan is not the only one who does this, I just happen to own it. If you look on ebay all you see is the same setup. So let's recap. The single bay setup costs more than a stack system, takes up twice the space, ande is no easier to work on. (Dan at Ginsan, please don't take this personally, I just hate the engineering, or lack thereof.)
