Browse Forums Building A New House 1 Jun 20, 2014 7:29 pm Hi All, As I'm planning my first OB build, Im thinking about ducted vacuum, but difficulty in getting the pipes through the roof cavities ( there's none, as we're using raked ceiling /roof SIPs) means im wondering about running required vac pipes under the slab to appropriate points under the walls. Does anyone know if this has been done before or if there are regulations that might exclude it? I suspect that as long as slab meets engineering reqs, essentially its the same as any wastewater drain system, so shouldnt be an issue. Anyone with insight?

I dont understand how the Vaccumm pipe is a problem as I would be more worried about other pipe and services that are much larger and more important. Have you considered placing pipes in strategic locations and ordering a longer hose if need be. Re: ducted vac in slab? 3Jun 21, 2014 11:54 am Are you sure every bit of the roof is raked? You would only need a spot to cross over or even just leave it on one side as the hoses are 12 long. May need more outlets only.....
