Ok made a little progress so far. I got the right bulkhead so now I can mock up my plumbing and paint the tank. I went to SpectraPure because I was having some issues with mt RO unit. They where extremely helpful A++ customer service, took me in the back to show and explain what was going on with my unit, tested my tap water, tuned up my unit, replaced the broken membrane housing clips. Best of all the owner threw in a free DI cartridge and a free chlorine test for me. I highly recommend SpetraPure RO units, they take care for their customers even though the issues where pretty much my fault. I will post up some pics later once I get some work done and have something to show.
