Everything Wayne said. And.........the same you said about all the unnecessary bends Rick. Plus, since you are in Illinois, I'm assuming you get those cold midwest winters. If the tube for that TPR exhaust to the exterior, it will be susceptible to freezing and blocking the pipe.

I know the configurations of TPR exhaust lines varies by area but in an area subject to freezing temps, sending these lines outside doesn't make sense. Straight and exhausting in plain view is what I look for. The homeowner needs to be able to see if there is a problem.
