Unconventional toilet vent.
Posted by Brian H. on January 25, 2004 at 16:52:48:
I recently bought a house with an apartment over the attached garage. The plumbing in the bathroom seems to have been done by an amateur, and one item in particular has me concerned.

The 4" vent stack for the toilet begins normally enough, but at about four feet in height, instead of continuing straight up and through the roof (which is just a few feet higher), it instead is attached to a piece of 4" flexible vent pipe (picture a dryer vent), which goes through a storage space and out the end wall of the house.

Am I correct in thinking that this is inadequate, and that the vent stack needs to continue up through the roof?

Thanks in advance!


P.S. Although the sink is tied in to this vent line, I can't figure out where the shower drain is tied in. Do showers need vents like sinks and toilets?
