faucet line tap for RO DI input line, need to avoid leak - of course

Hi,
Currently I have this simple looking, plastic valve that taps into the input line of cold water under my bathroom sink: https://reverseosmosis.com/products/...SABEgJdxfD_BwE

I'm worried about future leaks, especially as the valve get's more stiff to turn it. I was thinking about
1) keeping it open always, and then putting a valve right after quick fitting. And having that actually control water to the RO DI. BUt before the line hits this valve I would have the line go to my leak on floor auto shut valve. From there it would go to valve two (gate or ball valve I guess you call it), leading to the RO DI. I'd have it this way because if that first valve (the T) is always oopen I feel it's less likely for it to fail b/c of too many foreful turns of the knob. The leak would more likely happen at the second valve, which I can stop flow to automatticaly with the water alarm shut off. (There's no way to shut off the water leading INTO the first valve with this alarm b/c that line is not a 1/4 plastic line, it's the metal main line.)
2) Using this as the tap valve:

3) Ideally I would have a quick release valve from the faucet out put itself (at the sink) but my faucet out put hole/threads are too narrow. I get a headache when I think about how to get adapaters to get the faucet threads to fit any quick release threads, unless someone can offer advice on that. I can post pics of the out put of that faucet, maybe someone has the same thing and is using a quick release like I really want to. I want to do that because that I feel is the leak safest way to go.

Thanks for any input.

I have a all plastic valve for my incoming similar, 20 years old and still works like new.

Mine stays on most of the time until I'm doing work and need to shut feed off.

You can use the bottom one as well, you still will need a inline shut off valve for media change. Its faster than turning the sink water off

That simple plastic valve is what I use, simply because 2 maintenance companies use it for their clients. No Worries.

ok..i guess I'll keep it. Though it's harder to turn, so perhaps replace it, and do option 1. I'm over cautious about leaks and water because i'm on the 4th floor :-D .
