Bungie, WOW I am impressed Nice view from your window and your plumbing looks VERY complicated
It looks like the set up I did for an autopsy table in a hospital many years ago
I would strongly suggest you label everything for the next bloke who comes along trying to figure out what the hell is all this LOL.
You did some pretty fancy brazing work and your copper bending skills are second to none.
I did notice that the T&P dischage seems to be reduced slightly and also connected to another line, I would personally have kept each relief valve discharge either seperate or increased the pipe size.
Honstly you did one hell of a job really nice work.
Thank you so much for sharing. Sylvan
