Flushing non-clumping litter with poop

The problem/risk to drainage systems is in the piping that carries the waste out of the building... specifically horizontal pipes and elbows. Most civil plumbing codes require a 1/4" per foot grade (downward angle), which is sufficient for the water to move solid waste. But a substance like kitty litter may or may not dissolve enough for the water to flush it completely. If even a small amount of 'flushable' litter settles in the horizontal piping, it can & will build up over time. Might take years, but it could end up being an expensive problem.

I can see where perhaps an apartment building might not have the extend of horizontal drains as an individual home. So the problem may be mitigated somewhat. Unless you have no other option, I still say be on the safe side, and don't flush litter into the system.

Edited to add; There's one more contributing factor... the newer low water volume toilets, some of which can barely move normal solid waste without flushing twice. That makes even easier for loose sediment to settle into horizontal pipes.

Some low flow manage to flush well. Mine is advertised to be able to flush golf balls. Anyway, I LOVE flushable litter, never had a problem, and will continue using it.

They have most likely improved them since they were first mandated, but I remember many people complaining about them back then.
Anyway, you may not have a problem with litter flushing, but my advice still stands for others who may have different plumbing than you do.
