I live in a 160 year old house. Plumbing is probably 50-60 years old throughout most of the house. There’s this pipe vent coming off of the kitchen sink (located on other side of window shown). It’s in incredibly ugly and I’m wondering if I can terminate it at the siding exit with a standard vent or if there’s a reason this thing is going above the roof. Thanks!
