Yup, some plumbing, but nothing like you are thinking.
The plan is to have an RO shut-off float, with an overflow above it for emergencies. That will spill into the sink.
The other uniseal will just be for a drain tap (ball valve). I may put a barb on it down the road but would need about 60' of hose to reach the tanks.
I was considering just a garden hose but ... what are everyone's ideas on a garden hose?
Maybe I should just bite the bullet and by vinyl?
