<div class="moz-cite-prefix">Glad it seemed to work for you.
Growing up, mom would pour a couple pots of boiling water down the
kitchen drain every few weeks. I can't say it was 100% effective
since I remember several times having to help dad disassemble the
plumbing to clean out the pipes on the driveway. But I guess when
done regularly it might help prevent large grease deposits from
forming near the sink.<br>

I would have bet a case of beer the boiling water wouldn't work,
because it would be too cool before it reached the grease attached
to a giant cast iron tee, and also it wouldn't get splashed onto
enough grease to melt it. However, a few gallons of hot sink water
followed by a gallon of boiling water, all while plunging
furiously, did absolutely nothing at first, but then a few hours
later there was no gurgling from the tub and it's been silent for
a few days.

class="">Maybe some of you have an innovative
solution...<br class="">
<br class="">
My house has a single cast iron soil stack that does
both drain and vent. When I flush the toilet, it sucks
air from the tub drain. The toilet and tub enter the
stack separately, but at the same height, using an oddly
specific T with a 4" toilet and a 2" tub inlet about 45
degrees apart. The tub does not have its own vent. 2
years ago I had a plumber snake the vent from the roof,
he found "stuff", and it was fixed. Last week it started
again.<br class="">
<br class="">
My kitchen sink T's into the stack at knee height, so
it's the highest item on the stack. My thought is,
because it's a straight T, not a sanitary T, stuff from
the sink is solidifying inside the T when the flow hits
the back of the T, and eventually forming a cap of
"stuff" just above the T entry, sealing off any venting.
I can't tell if the sink is also being used as the
toilet's vent because there are too many walls in the
way to hear what's happening.<br class="">
<br class="">
My other thought is that the "stuff" is growing like a
mold, and sealing it off. Does stuff grow in drains?<br
class="">
<br class="">
Any thoughts on what it might be, and how to prevent it?
I rarely put oils down the drain, and when I do they are
cold and mixed with Dawn to emulsify it. There isn't
enough canopy for leaves or squirrels to get in the roof
vent.<br class="">
<br class="">
thanks,<br class="">
