Merry Christmas Everybody,
Regarding Sewer Vents:

1. We would like to avoid installing one through the roof, and are considering bringing the vent out the side of the house.

2. What are the required clearances to the soffit above, and windows?

3. Can it be terminated horizontally, without turning vertical? Depending on the required clearances this could allow us to get the pipe a distance away from the house and out beyond the soffit.

4. If we have to be above the soffit, we may come out the siding and elbow up and out to get above the soffit. As long as slope is maintained to the drain on all horizontal runs of venting, is there a maximum number of bends in the vent pipe (this design would require 4, 90 degree turns)

Thanks in Advance

Ten feet away from a window that opens.

Thanks Terry,

A couple or questions about the diagram:

1. Is it okay to run the sewer vent in front of the fascia and above the roof line? If so, how far above the drip edge would it have to be?

2. Can the sewer vent be terminated horizontally? There are no windows on this wall, so it's a consideration to run it out the side wall of the house and extend it out away from the house (if it's okay).

Thanks

if you terminated it horizontally, the wind would "pressurize" the system when it blew from that direction, and could create a negative pressure when blowing from other directions, like blowing across the opening across a bottle to create a whistle.

Is it against code to terminate horizontally? Not that I would want to after reading the above point, but I'm curious.
