The Apollo Welders are working out the routing for the HEPI Plumbing on the West side of BSC8.  Attached are a couple of photos.  First the main lines are coming from the East under the chamber and turning up to a valve.  This is the West side of BSC8.  The lines then turn horizontal to a manifold.  The 1" lines branch out to four 1/2" lines that then run over to the "corner" of the chamber and turn up to head for the HEPI Housing at the top of the Pier.  The criss-cross is for supply and returns going to each Pier.
The second photo shows the lines running vertically close to the chamber to the left of the View ports and finally turning horizontal again and connecting to the four-way recirculation valves.  We hope to have given as much access as possible to the viewports for potential use.
Robert has looked over the installation and he isn't concerned about noise.  JohnW has blessed it with regard to chamber/spool access.  We'll be close to the plumbing when ever the spool is removed and need to be aware of that.  We may have interfered with RichardM and cable trays but he wasn't too concerned about dealing with the plumbing/valve plates.
