Did you get the 300psi vessel for Joe also or did you pay extra for the 600psi? Also, you got the series 4 procon pump... What hp motor did you get/are you using?

My bush is the same size as yours. I'm going to attempt to build a RO very similar to yours. I was planning on using braided hoses from www.hosecraftusa.com (model ra1-as) for the high pressure lines. Don't yet know what low pressure hoses I'm going to use.
