Sanitary tees can be used for vents above the flood level in the horizontal postion.
Below flood level, they should remain vertical.
King counties plumbing website states..
Used in vertical position only. Trap arm application and horizontal to vertical drop.
What I'm not clear on is, can a Sanitary Tee be used in a Vertical to horizontal vent connection? (ie tying a vertical vent into a horizontal vent.)
Thanks for you help.
