The Georgia amendment allowing this is dangerous. It violates every plumbing code (must drain via gravity, cannot be trapped, can't have more than 3 90° elbows), and the valve manufacturer instructions. In the event of a high temp or high pressure failure of the water heater, IF the safety valve functions that mess of plumbing is going to burst...either between the first and second elbow or the bleeder cap is going to become a projectile. And that's a big if. The valve is likely to be corroded from water trapped against it and fail to open, turning the tank into a bomb. That water heater would be safer without a drain extension at all.
I was home alone as a teenager when a pressure be vessel exploded. Not an experience I would recommend.
