No vent stack?
Asked Oct 5, 2007, 05:47 AM
I recently purchased an old house and the toilet drains slow and bubbles. I cannot locate any plumbing venting at all. The plumbing is all located within 4 ft of the main drain going out through the basement wall, with the kitchen sink, bath sink, tub all connecting to the toilet line then out through the main line. The main line is in the basement wall directly below a window, is it possible to run a vent off the top of the main connection out the window and up the side of the house? Will this help relieve a bubbling toilet, barring any clogs of course.
