This is a followup post to an old thread of mine. Special thanks to hj and johnjh2o1 for steering me in the right direction. To make a long story short, I'm restoring a Monoflow system in my house. I contacted B&G and one of their engineering reps helped me calculate pipe size, pumps, etc. I purchased all the materials and would like to start the project soon as the weather is no longer cold in New York.

I have one remaining issue that bothers me and I wanted to run by you guys.
Since I'm finishing this basement, I would like to run all the pipes flush against the floor joists above. In order to do this, I would have to run the main along the bottom of the beams and the Monoflow tees would be horizontal (0 degrees) with riser pipes flush as well.
In all the homes I've been in with Monoflow, the main always hangs down maybe 6-9" and the tees are angled at 45 degrees. I was told this is done to purge air from the risers as gravity forces the water down and the air up. Is this true? Would it be OK for me to plum with tees at 0 degrees? The engineering rep for B&G said this doesn't matter but I value your opinion.
