Strange white stuff
wrote:
Had fun shoulder deep in blocked drains today, but what I fished out
puzzled me a bit. The pipes were caked to blocking point with a soft
white solid. I cant work out what it is though. There were a few rice
grains floating about, so perhaps a block of congealed rice? Also
wondered about solidified washing powder, but I would have thought
that would wash through, being water soluble.
Any ideas?

It's almost certainly fat.
Having unblocked masses of the stuff over the years from various drains and
manholes, and knowing the cost and amount of work involved in replacing
sections of drain that have needed breaking to remove such blockages, I
never put any animal fats down the drains, vegetable oils are usually OK
because they normally stay liquified, but drippings from cooking meat,
especially sausages, get's scraped into the bin once solidified or poured in
when only slightly warm.
