Looks good indy, I would put water in it and test it out that way if you have any leaks to address you wont have fertilizer on everything. Did you put filters in with your office plates. Today while I was testing mine out I had a row not right and pulled it apart  to check the filter and found that we over looked it on that row and there was a piece of plastic from the tank hung in the orfice plate. I'll get some picture of mine tomorrow.
