| Is it O.K. to run a pvc vent pipe up through a concrete wall? My kitchen sink will be on an exterior ICF wall and said wall would be the easiest place to vent the sink. I was just wondering if this is acceptable proceedure. Thanks. |

local codes may require the vent to go through the roof, best to check it, and the reqired diameter....
in that case just run a vent stack up the wall and through the roof. depending on size it can be run through the foam after the pour or in the concrete flush with wall...

Paul, A method we use regularly for locating the kitchen sink vent line is to frame the kitchen window opening from the lintel height all the way to the floor level, as if it were a door. This makes the space under the kit. window easily accessible for the drain/vent, water supply lines, and later, disposal and dishwasher wiring. I run the vent line horizontally thru the buck material, use an elbow to run it vertically up thru the top plate where it can be connected easily after the walls are poured. Typically, 2" Sch 40 should be adequate for a vent, but you may need to verify this with your local plumber. As for the gaping hole under the kit. window, simply attach a bottom sill and infill framing with your material of choice, sheath it on the outside, insulate on the inside and prep. for drywall. I know this leaves a large, non-concrete wall space under the window, but since the sink cabinetry will be placed there, I haven't found it to be either a thermal or acoustic problem. In any case, having the plumbing and wiring easily accessible for both construction and later maintenance/repair makes this our method of installing kit. window utilities. Hope this helps.

Terry,
That was excellent advise and not just because we do it the same way. Due to the amount of wiring and plumbing that does go into the space below the window when the sink centers under the window, makes for an easier installation. The cabinetry does provide some protection and when considering that you've constructed a very efficient envelope for the entire structure that small space that you have to in fill with standard frame and batt makes for a small impact.
The ICF system we use allows us to form the outside of that wall section, pour the rest of the system, come back later and form the inside of the wall with the ICF and pour that section also. |
