Prairie dogs along the front range of Colorado, deer in the Colorado mountains…

I wouldn’t cap it but put in a Studor vent if there is a chance that you need more venting.

They make what is called a studor vent for this situation. Not sure if there are code restrictions for different areas. If allowed you can put them under sinks etc to get better venting of sewer lines.

Wish I could try Wayland, can’t seem to get it to load. Fortunately when they pushed the update of Wayland as default they didn’t remove x11 support. Still been pretty happy with kde neon for the last few years
