Well, our small plumbing problem has turned into a bigger plumbing problem. The plumbers at our house yesterday discovered that the drainage problem was not a blocked pipe inside or a capped vent, but a problem with the drainage pipe running out to the septic tank or the pipe from the septic tank to the leech field. The septic guy is supposed to stop by and diagnose the problem today, but we've probably got a crushed pipe or one that came loose during the grading of our yard.
So, we can legally move in, but we can't use any plumbing right now, which is a major issue! I'll update as soon as I know anything! I'm mainly anxious to get started on my diet. I need to find my cookbooks!
