I have a waste vent terminal that will be 2 m below a window (2 storey house). Can I leave this terminal there, or should I extend it above the windows (adding 3.5 m to it and having an ugly pipe on the side of my house)?
What is up to code? What is manageable? I'm in Brazil and our code doesn't mention clearance to vents below windows.
Edit Rough sketch (vent in red 2m below the two windows in blue and about 1.5m above the doors in brown):
Can I left the vent terminal in this position, or should I extend it above the root line?
