I am at a loss for how to hook up my Cloud RO filter system.

We have a dual cabinet dishwasher system so 2 drain lines are already hooked up to the garbage disposal inlet. I am worried about backflow to the filter through the RO system discharge line if I branch it off the already installed wye for the dual dishwasher lines.

The other issue is I don’t know where to drill in above the S-trap if I decide to go that route.

Thanks, will most likely contact a plumber to aid in the install regardless to be safe.

Let me start by saying I don’t ever touch plumbing because as a homeowner I hate water and don’t trust myself to know the nuances associated with plumbing.

That being said, I bought a Cloud RO system to install underneath my kitchen sink and am having a heck of a time deciding on where to connect the wastewater line. I don’t mind drilling but don’t see a good spot below the disposal above the P-Trap.

Also, I considered adding a RO wye to the disposal inlet but I have 2 dishwasher drains with a wye connecting both to the inlet already and I’m afraid of back pressure from both pushing dirty water back up the RO drain tube. I don’t think the dishwasher is air gapped? But just high looped?

Any advice would be helpful before I just call a plumber to hook it up for a couple hundred.
