I recently spent a few days helping a friend install vents in the plumbing drain system in a log house he's building. I'd never really thought about venting, so when I got home I checked out my venting and discovered that I don't have any. This place was renovated, or being rerenovated, by a couple that went broke and we bought it from the bank so I don't know what the plan was. There's about 35' of 4" ID pipe to the outside wall and on to the septic tank. All the drains come together within 5' of the other end of the pipe. I can easily put a vent pipe through an outside wall but I'm wondering if it should be at the septic tank end or the other end. Brian, in Cedar
