loss of suction over a long run

[Wood_workur]

I have a shop vac, and I would like to set up a dust collection network for it, because a dust collector isn't in my (near) future, unfortunately. I was wondering if there would be much of a suction loss over say 20 feet of pvc sch40 piping?

Suction

Just finished making a 10 ft PVC run with a tee for the rear of my saw and the new Sharkguard. Seem to pull fine.

You don't say what size PVC you're using, so I'll assume 2-1/2". You won't lose much at 20', but you will lose some. You can always up-size to 3" and use bushings to get back to 2-1/2". That will minimize your loss. PVC pipe is smooth inside compared to flex hose, so going to PVC will help some, even if you don't upsize.

Yes, I did mean 2.5"

ever try to suck up a soda or even a milkshake through a small diameter straw? It makes a difference!
