I run into a small issue with my tank setup. I was planning to run a 1/4 RO line from the kitchen, down to the crawlspace and back up to behind the tank. There is no easy way to get the line from the kitchen sink to under the house. I thought i can drill straight through the floor, but i didn;t realized i have tiles under the cabinet. Which means i have to drill through tiles.. which is a pain. Scratch that plan.

Plan B is just pull the RO line across the hallway once a week to my 10G ATO container and also 10G mixing station. I have a 400gph RO system, and this should take 1-2 hours at most.

Is there a quick disconnect for 1/4 RO tubing? The John Guest fitting, it doesn't appear to be meant for frequent connect and disconnect.

Any suggestions?

Since you have a crawl space, you should be able to drill through the 2x4 bottom plate and come out behind the cabinet through the wall and the back of the cabinet.
 
Is the sink up against the wall? Instead of going down through the tile can you go into the wall and then down to the crawl space?

Or can it follow your drain pipe to the crawl space? I have similar tile under my sink so the drain pipe goes sideways to another cabinet and then down

Yes, sink is against the wall but I'm not super handy person. fishing the line through the bottom plate, to the wall, and cabinet is not straight forward. I hate to messed up the custom cabinet $$.

I called a Plummer and they want $500 for this job. Its crazy. Coming back up from the crawspace is easy, i can route the line next to the laundry drain.

At least if it doesn't look pretty, it's inside the cabinet and hidden! :)

Mine goes sideway then only goes down. I don;t know how i can route the RO line follow the drain, unless i cut a big whole in the cabinet and the wall.

I'm no expert, but if I was doing this and the sink was against the wall, I'd drill a 1/2" hole in the bottom plate and cut a hole in the cabinet and wall to fit a low voltage gang, then put a brush plate over the gang box. Feed tubing through hole and then through the brush. If you ever want to remove the brush plate, you can replace with a solid blank plate.

that might work. I'll crawl under the house again this weekend to scope things out. I have a very low (maybe just at the min code) crawlspace. I literally have to do commando crawl on my belly to get through HVAC line. Did some simple plumbing work under the house, and its not fun.

Interesting idea. I would have thought you will wear out the connector, but never thought about the line.

the connector will be fine... there's a metal clip inside that does the biting of the tube and a rubber \ silicone gasket. if hot water application, the gasket will wear eventually... but for cold water, you would have to be doing the plugging and unplugging round the clock for ages before any failure of the fitting itself. When it does wear, it's 30 secs and $5 to replace. And, if you're really concern, you can always put one more fitting as man-in-the-middle. and only have that one connector to worry about... :)

Your plan is essentially how I do it. But I use two valves. That way I don’t get any dripping. You don’t need to watch the video. You can see my connection by the dog in the screenshot below.

That seems like a pain disconnecting push connects every time. Sometimes those things get stuck in there real good. It's a little pricey for a connector, but I'd probably get 1/2" cam level quick connect and 1/2" to 1/4" push connect adapters.

Awesome Randy. I just ordered the cam level quick connect. Will use this for the time being until i'm motivated to crawl under the house. Thank you!

It’s really not. Takes me 1 minute to set up each time. I have found that the valves only last about a year before they start leaking after being pulled apart so often.

those things you suggested are way more heavy duty than needed to me.
 
All drains lead to the ocean...
The kitchen sink has a drain; it should go down and you should be able to spot it from the crawl space. There are shut-off valves with an added 1/4” outlet.
If you are able to get the RO line parallel/alongside the drain, easy piece.
A picture is worth a thousand words... couple pictures 2k words and so on...

Unfortunately It’s not straight forward as that. The drain line goes sideways before it goes down. It’s not easy to get the ro line to follow the drain unless I open up a big hole in the kitchen cabinet and wall.
