Time for a little more work on the plumbing...
These are the upright pipe and valve assemblies. They are very small and the photos aren't great since I don't have the proper lights.
You have to watch how you put the valves on. A closed valve handle is in line with the pipe and the flow of the liquid. So if you model this pipe on, the valve will be pointed straight up. Since I didn't want any leaking chemical I made the valves closed. The valve handle would be perpendicular to the pipe and on the side of the gang way. None of this is in the instructions of course.
I put the flanges on the pipes with ACC, then later added a drop of Tenax 7R. This fused them together well.
Here are the four pipe sets. Took me about an hour.
