Horizontal Vent Maximum Distance

[i_am_chris]

Hiya,

We are trying to figure out a way around cutting through the yurt roof for the vent stack. We can locate the pipe on an outside wall if we can get the sink vent to go horizontal in the walls. What would be the max distance we could go with this horizontal vent?

I'm assuming a 1.25" trap - with 1/4" / foot slope you must have a vent within 5' of the trap. If you have 1.5" trap - you can go maximum of 6'.
