Good evening all, I've been reading and searching here till I'm blue in the face, and now I have some questions.
I am building a house in WV where there are no building or plumbing codes/permits/inspections. This is great because it's less headaches, but it would be nice to have someone check my work over before I pour the slab.
My major question/concern is how to vent toilets underslab. I have read that santee's are basically not to be used underground, although I have seen them in several reference materials posted on this forum. I have also read where flat venting is not allowed either.
In the picture below, would the venting method be acceptable if the san tee were a wye/45 combo? Basically an elbow from the main up to a 3x3x2 wye to the closet flange? I didn't have a wye of that size on hand for mockup.
The other way I came up with would be to roll a wye off the main after the toilet, but it would result in a flat vent for about 2 feet.
