This thing is freakin confusing!!!!!! Thanks Derrel, I looked it up. I am just totally confused as to which lines go to what tank and so on. The trailer was made by alkota and they only made about twelve of them ( so says Jimmy at alkota ) the problem is that each was made a little different and the Dosatron was added after on this one ( so says Jimmy ). I tried for three weeks to get a manual for it but they are not available.the guy that originally drew them has left alkota. I spent three weeks emailing back and forth with them and they have nothing about the plumbing. they do have all about the trailer, the tank sizes, the pressure washer, tires etc. but the there is nothing about the plumbing.If Jimmy from Alkota says they made 12 of them then perhaps he can tell you how it's designed.
