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.=20

I'll get some of that bacteria/enzyme stuff as preventative maintenance.=20=


The scope sounds like a great idea but the only access I have is from =
the roof and it's about 12 feet from vent to to sink entry point. If =
there's a dry day I'll drop a rock on a string down there and see what =
happens.=20

Thanks all!
