Hello all, I just bought a new house (built in 1921) and have just recently noticed a sewage smell in the upstairs. The upstairs was an attic converted into a large open bedroom w/ a bathroom which includes a standing shower. It does not appear that the smell is coming directly from the shower or sink drain. You only smell it 10 - 15 minutes later in the open room, it doesn't seem to be concentrated in the bathroom. The first time I noticed the smell I had previously been running the sink for an extended amount of time with cold water only. The second time was after I took a hot shower. The down stairs bathroom has no issues whatsoever. Could this be due to a clogged vent stack or vent that terminates in the attic? There doesn't appear to be anything leaking in the house, what is my next step?? Any help would be greatly appreciated.
