Am I the only one who is anti-sink garbage disposer? While we have two of them (two different houses), we never (or very seldom) use them. I don't like the idea of sending ground-up food into my drain lines to cause problems, so everything goes into the garbage container under the sink. I even have one of those screen wire strainers that goes into the drain above the grinder to catch everything. Wife feels the same way.
BTW, we also use screen wire strainers in the shower drains. You would be surprised at how much hair, skin, soap scum, etc. it catches. I no longer have any plugged shower drain lines. The only problem is that they generally need to be cleaned after every shower, but that is simple. Just press a wad of toilet paper in it, everything sticks to the TP, and I flush it down the toilet.
