hello there,
my house (built in 1953) has all plumbing fixtures on the same floor. The drawing above shows the dwv system. There is one 3" vent through the roof. While I have my laundry room ripped apart, I am wondering if i need to include additional venting for the clothes washer and kitchen sink which are on the opposite end of the house from the bathroom and vent (about 25-35 ft).
Unfortunately the kitchen sink is on an exterior wall underneath a large window, and the nearest place to add anything would be about 10-15ft away. I am really hoping to avoid that.
I don't notice any drainage issues with the current plumbing, but, since my home inspector made a comment in ins report about the kitchen sink not being vented, i don't want to have to rip everything apart again if i sell the house in a few years because something is not vented properly.
let me know if i need to provide any more information. Thank you!
Jamie
