90 vs 45 degree pvc plumbing

[JAMSOURY]

What are the differences in using 90 degree pvc elbows rather than two 45s? Which is quieter?

45s

45's cause less resistance to flow... as a one time plumber can confirm

Actually, watch the BRS videos. There is no difference.

Plus, I did a quick mock up of it because I didn't believe it either. But, it's true. We were within a gallon or two per hour (calculated) either direction.
