Vent exit horizontally through gable?

[Jm66208]

Im doing a bath remodel (full gut) in an 80 y/o 2 story house. Bath was added at some point in the past, and none of the drains were vented. House has a 12/12 pitch slate roof. Can i run a vent out horizontally through the gable wall, up as high as i can get it?

If it is going to point "sideways" then whenever the wind blows from that direction, it will "pressurize" the drain system.

Well, i could put a 90 on it and terminate it vertically, or i was hoping there may be a cover available similar to the ones the HE furnaces use.

In most places, the vent must extend above the roof...just running it up vertically some probably won't cut it with the local inspector. The outlet can be smelly, and if it isn't high enough, won't be dispersed properly, and you may start to smell things if you have windows open. Because the vent should be installed with slope, just like a drain line, if any precipitation gets in there, it will drain and still stay open.

Put a 90 on it to put it vertical. It should daylight higher than the roof, or 12 feet from a window that opens.
