I'm thinking about routing part of my DC piping under the floor of my pier-and-beam shop. Anybody see a reason not too? Only question I have is one of condensation and pluggage, guess I could put a cleanout at each end just before it goes back up into the shop?

What I'm trying to accomplish is simply to clean up the walkspace in my shop by having the DC piping come up through the floor at my centrally located tools like the TS, etc, rather than having to run over from a wall. This is a new system install, so I have a clean slate right now.

The only problem I would see is if the crawl space is not weather protected.  In the cold season, the warm shop air might condense some water on the walls of the pipe.  Insulation may minimze that possibility.

As I recall, up and over is better than down and up again.  When you go down and back up again, it creates places for dust buildup inside the pipe, and that restricts airflow.  I stand to be corrected on this, since I am working from a vague memory of something I read.  Maybe on Bill Pentz's site.

If you've got sufficient suction and accessible cleanouts in your line, there should be no problem with this.

My experience, and I have a bit with plugged pipes as my DC (with a cyclone)is a bit small and the run to the resaw is a bit far and the wood I typically collect dust from is a bit wet, is that cleanouts won't do you a lot of good. This isn't backed up water like in a waste water system, that has a bit of head that will carry it through when the blockage is removed. You need some way of clearing the blockage and then getting things going again. For me, that has meant taking some pipes apart and banging them out and putting them back together again. As long as you can do that from under your shop you should be OK.

Good luck!

Thanks, all, seems worthwhile to try so I think I'll go for it. Worst case scenario, it doesn't work and I run it inside. Just wondered if someone else had tried it.

As far as the low points, I figure it shouldn't be much worse than putting a run on the floor (I'm thinking like for the belly pan on my TS). That run would still have to go down then up to the DC. Going under the shop would only be a few inches lower, but would be more exposed to the elements.

Just trying to eliminate some tripping hazards.

While you're at it, run the power for the table saw in the floor, too.

Yessir, that's in the works. Along with power from the floor to my island work bench (which you also talked me in to) with receptacles on boths sides.

And, of course, doing the split receptacle thing for the day I upgrade my TS to a beefier 220V unit.
