I am upgrading my dust collection piping to 6. Since it is just me, only one machine at a time will be running. From the 6 branch line, I will be putting drops to various machines, terminating in a 4 flexible hose. The question is, do I continue the 6 down to the 4 flexible hose or do I reduce down to 4 at the top of the drop, right off the 6 branch? I would first use 4 piping on the drop until the 4 flexible hose. Or should I first reduce to 5 at the start of the drop terminating with the 4 flexible hose?
Thank you.
