I see there are these baby-wipes that are labeled as flushable. These
in particular are Wal-Mart "Equate" brand. Supposedly safe for septic
systems. They're supposed to break down like toilet paper.

Out of curiosity, I set one in a container of water. After several
days, it seemed to me to be still quite intact, plenty of strength,
whereas I've observed that toilet paper will disintegrate within
minutes, if not instantly.

Is this not a valid test? Will the "soup" in a septic tank will
degrade these wipes more aggresively than plain tapwater?

Anyone had any problems with these?
