Well, I don’t want to be a plumber someday. There are so many connections, pieces, parts and sizes. We have been working on the plumbing for quite some time now. It seems that we are getting it done, but there is always another fitting that we need. So we go to Home Depot, nope, they don’t have it. So we go to Lowes, they have one of the fittings. Next stop Peter’s Hardware, formerly Ace Hardware, they typically have something close to what we need. Last stop is John’s Plumbing, a real plumbing supply shop, nope, we don’t sell barb fittings. So we end up back at the bus with something that might work. It certainly now looks like I did the plumbing. We have a blend of pex, nylon, PVC, stainless, bronze and brass. I am sure that goes against some code somewhere. With that mix we are able to make 1/2″ barb, 3/4″ barb, 1/2″ npt, 3/4″ npt, 3/8″ npt, 1/4″ connections and we are not done yet. No metric yet on this project, but the rest of the bus is littered with metric as well. We have not even tested for leaks yet. This project is far from over.
