Central Vacuum plumbing


Previous owner decided it would be nice to take the central vacuum. I installed a new one but the short little flex that was there wont reach the new inlet.

I know its not recommended but can I just go to home depot and use regular home dept sch. 40 pvc elbows and such? Just order a few more feet of the flex from online?



Just looking for the simple option. Thanks

SCH40 won't work. It's a different size. I think Home Depot sells the correct tubing. Unless your manual specs a flex tubing you can use hard pipe.

I'm sure there's a CV dealer somewhere close to you.


All you would need to do it right is three sweep 90's, no more than a couple feet of pipe, and some PVC cement.

Better to use hose clamps on the piece of flex.

Step back and take a wider shot of the setup. BTW, you can use a #20-22 Beanies, or if you have a spare telephone jack box laying around, the biscuit plates come in handy for stuff like this, for the wiring for the vac.

I live in Bay Area, CA and can't find any local CV dealers. Gotta keep searching or buy online.

The 3 90's and some pipe is exactly what I need.

I'll fix the wiring, thanks for the input

I got everything rough connected and had a couple questions:


IMAG0417 by amdspitfire, on Flickr


IMAG0418 by amdspitfire, on Flickr

1. Position of clean out looks ok? The vacuum came with it so I figured its good to use and I believe thats about where it should go.

2. Do I glue the coupling to the actual unit too?

3. Regular PVC primer & cement for connections ok?

I would use a Fernco, so if you have to remove the unit, you are not having to cut the pipe off. Now of course, there is nothing wrong with using a coupling that you can undo without cutting, but the fernco is the better option. Also, the manufacturer directions that came with the unit, or available online at NuTone's website, would state what you would do in this situation.

The last fitting to the unit does not need to be glued. Looks like you have a nice tight piping job.
