Not sure if they can fail though. I'd imagine the ones that have the flush valve built into them could.

RODI gives me 1 cup in 80 seconds and the waste water gives me 1 cup in 35 seconds. Check my math but that is only a rejection rate of 2.2. It is my understanding it should be 4 to 1.

Yes they can fail, but more likely start to function out of spec
