Aquasafe ro/di discharge line question
 

Finally hooked up the unit.

Says to fill and flush bladder. Assume with the faucet off, when water stops from the yellow discharge line, bladder's full?

yup....that should be right

I let mine fill up then let it all run out down the drain...although i HAD to try it..and got a tummy ache. :(

haha

I don't think its the resevoir that needs to be flushed so much as the DI and final filters. I do the same proceedure every time after replacing those.
