First off, I hope this is the right forum.
We are planning a remodel of a bathroom in a 1960’s vintage ranch in Connecticut. We would like to remove one of the interior non-load bearing walls in the bathroom, but unfortunately, that is the wall that is used as a chase for a vent pipe. In general, we have two full baths back to back with a common wall between them, where most of the plumbing takes place. The vent line in question t’s off a shower floor drain line, takes a short horizontal run, then goes vertical through the wall (that we are looking to remove) and up into the attic where it ties into the main 3†vent line (which then exits through the roof). I’d like to re-route the vent line coming from the floor drain by connecting into the main drain/vent line at another location. The main drain/vent line starts off in the basement where both toilets, as well as the bathtub and shower feed into it. From there, the 3†line travels vertically through the common plumbing wall, and up into the attic. In that common plumbing wall, the sinks from both bathrooms tie into the line. My idea is to re-route the small vent line from the floor drain, by making a short horizontal run, then a 3 to 4 foot vertical run, then finally a 4 to 5 foot horizontal run where it would connect into the main 3†vent pipe (stack?). I wanted to know if this was OK, and if so, should I be concerned about the pitch of the horizontal run into the main vent pipe, or the height of that horizontal run relative to the fixtures (sinks,etc.) that feed into the main drain/vent line (seems like I came across some thread that indicated that there was a minimum distance above the highest overflow point, which I guess would be the rim of the sink(?).
Finally, we would also like to build a recessed cabinet into the common plumbing wall, right where the main 3†vent line is. Is it OK to make that 3†line jog around the planned nook in the wall (i.e., 90 degree bend to right, over 10â€, 90 degree to vertical, go past nook, 90 degree bend left, go over 10â€, then 90 degree back to vertical)?
Thanks in advance for your assistance.
