I am going to install the reverse osmosis unit under the sink soon, it comes with a bladder tank so it is enough to pressurize the icemaker.

The problem is running to the refrigerator which is 6-8 ft of cabinets in the way. I plan to drill some holes on the back of the cabinets and run 1/4" plastic line through.

There is a shut off valve behind the refrigerator but I plan to not use that. I don't see why I should use tap water for my icemaker / dispenser when I already have a better quality water.

I thought about running the RO off the icemaker supply valve but then I needed to run a drain back to the sink too, so more or less the same issue.

Is there a question somewhere?

I would run 1/4" copper tubing instead of that poly tubing. Much stronger and more lasting material.

how easy is it to run the 1/4 copper in a straight fashion?

As easy as running the poly. Keep it high in the cabinet to minimize the possibility of damage.

damage from rodents or what?

After this ice maker copper failed when I was away a few hundere miles the wife insists on plastic. She really didn't like working toward her plumbing license. If drywall makes it fail she seems to not want it.

I have seen more poly failures than copper failures. I suggest the tubing be run high in the cabinet to keep it from getting banged by pots and pans.

Check your install directions, my Watts R.O. filter requires specifically - plastic tubing because "Note: R.O water should not be run through copper tubing as the purity of the water will leach copper and cause an objectionable taste and cause pin holes to form in tubing." Be sure the return/waste, if to hot water line, is minimum 25' away from tank. I don't run to hot, cooling it- I run to my exterior water barrel storage watering the plants with the excess chemicals/impurities. They don't mind, still growing- haven't complained yet...

I second that. Correction, I forgot RO water yes it should be plastic. I don't know anyone that ever ran a 1/4 " line from a RO ice maker so I was confused.

The point if it's not an RO system use 1/4 " soft copper roll and leave enough behind the Refrigerator so you can pull it out for service and cleaning.
