Just seeing the last few pics, I was gonna ask the same.Most of it is clean in place circulating near boil water through everything. I work with triclamp fittings at my day job so I'm pretty quick with them.
No way I'd be using that without building in a CIP process (i couldn't imagine a full breakdown/scrub of it). And I'd be using caustic too (dunno if you can get a built caustic at home, but you can definitely get lye), I wouldn't rely on boiling water to get the job done (or even PBW for that matter). That's far more advanced than most smaller brewery pilot systems I've seen.
Add me to the jealous club.
Cheers
