Listen buddy, I apologize for being sarcastic. But I truly meant that maybe I was wrong. Maybe I didn't do a good job of describing the situation. You are the one that SCREAMED that I didn't know I had sewer stacks in my house. I thought I made it clear in my first two posts that this was non-septic vents that were not inside the house. Again I apologize for pissing you off. I will leave the sarcasm at the door.
