30 Ga Duct Pipe
I have read some complaints about 30 Ga duct flexing when seeing full vacuum from the DC. I tried it with my system with 4" duct and didn't see any. A friend wants to get rid of his flex hoses on the floor and wants PVC. The DC inlet is 6", but Lowes, etc. don't stock 6" PVC. If it were me, I'd use the 30 Ga duct, but he isn't enthusiastic about it. Any thoughts on 30 Ga 6" duct?
I'm going to look up recommended velocities, etc., maybe a 4" PVC header is just fine for his DC and 6" isn't the best.
