i had thought that the dos doesnt need to be plugged into power thru an outlet, rather you can power them via the aquabus. i pulled the power plug, and kept the aquabus cable in, still get the 'orange' solild light, but it will not work when i push the prime button. am i doing something wrong?
also, it looks like there is air in the tubing, could this be the issue? shouldnt it still operate when i push those buttons?
