Kitchen sink drain reverse osmosis connection
 
For reference, see the kitchen drain photo in this PDF:

http://dlshare.s3.amazonaws.com/temp/sinkAndLaundry.pdf

There is a reverse osmosis water filter system installed, and there's a red plastic flexible hose from reverse osmosis water storage tank (like a small gas tank) that pipes into the drain (didn't know those systems have such connection?)

My question is, I just got the house and if I don't plan on using reverse osmosis system anymore, do I need to cap off that drain connection where the red valve is? What would I use to cap it off? Some links / reference photos of what to cap off with would be nice.

Or better to replace the drain pipe connection right there with one that doesn't have a connector for reverse osmosis instead? Might be good idea as drain is a bit dirty.

But wanted to see which is simpler, cheaper, and/or better solution.

in my opinion after seeing picture it would be wise to change strainer basket and tail piece at same time make sure you unhook osmosis if you take out drain/flush hose

I agree it all needs to come out.
Anytime I see one of these installed I know there's something wrong with the water.
Have it tested. May be as simple as adding a water softner.

Joe, you mean test the water? And it might be hard water containing mineral deposits?

Also, when you say see one of these installed, are you referring to having reverse osmosis filter (plugging into drain plumbing) OR just having any water filter installed in general?

The osmosis filter's also just installed for the water filter faucet, not to the sink faucet or elsewhere. So I'd think any water filter makes more sense than a water softener system to address cleaner drinking water, unless we're talking about cleaner/softer water throughout house plumbing to not damage/scale up the pipes with mineral deposits.

On a related note, can't tell if pipes within walls are corroded and worth a repipe w/o tearing up the walls right?

Old steel pipes? Plan on changing them before they leak or close up from rust.
Hard water will corrode the plumbing, make it hard to form suds with soap, load up the bottom of the water heaer ect.
