Sewer Gas smell and bubbling toilet?
You all have been helpful in the past, so ill try again ;)
This just started happening recently...
I have a laundry room /bathroom in my basement.
Recently (as in the last three Sundays..laundry day) when the washer drains the first time there's a sewer gas odor in the basement. The odor goes away relatively quickly and does not return through 3-4 more loads of laundry. The toilet has also started bubbling as the washer drains and if you flush the toilet it is VERY slow to drain. I think its a bubble vs a gurgle, I'm not sure how to tell the difference.
The sink and tub in that bathroom seem to drain just fine, though I haven't run an excess of water down them while this is occurring (just turned the water on for a minute or so).
The toilet remains slow for 12ish hours, meaning I've gone back down a few hours after laundry and it's still slow, but the next morning it's always fine.
I haven't altered anything and like I said it just started happening recently.
Venting? A clog somewhere? Thoughts?
Thanks in advance!
