RO unit help

[GreenSpottedPuffer]

Ugh...always have problems with these things!

Just set up a new aquasafe maximus 100 gpd unit and something is wrong. Gone over the set up a few times and can't figure it out.

There is absolutely no water coming out of the waste water line. All the water is coming out of the "good" water line (through the DI).

All I can figure is that some lines must be messed up.

Any ideas? I know its hard without a picture...
