The PVC pipe has shown no problems. It's completely free-floating, with 
hose at all connections, so the lack of flexibility has not been a problem.

I used the holes in the bulkhead that the previous owner drilled to 
install the Mansfield treatment system. The downside of my installation 
is that the PVC pipe is horizontal or slightly uphill where it heads 
toward the holding tank. This leaves a significant amount of liquid to 
be held out by the joker valve.

If I were to do it again, I would get the up-hill plumbing as quickly as 
possible so that it would drain from that point to the tank.
