I need plumbing help!

[rlanicek]

I have a Culligan water purification system under my kitchen sink. It is plumbed with plastic.

I want to run a stainless-braided water line to my refrigerator.

Is there a good way to connect a stainless line to a plastic connector?

See the pic. I want to replace the white line with the stainless water line.

Alternatively, can I replace all of those plastic lines and fittings with stainless? Where would I find stainless water lines that short?

Thanks!

Imo best is a swagelok tee in 304ss two compression fittings with ferrules to prevent collapsing the tube. The outlet/leg will be NPT and then you can attach or adapt to whatever you like.

See also yor-lok, duo-lock as competitors who make about the same product.

I certainly hope your plumbing job goes better than my recent one. Started with a leaking faucet. Found old late 1950's iron pipes still in the wall. The others are CPVC. At least yours is above ground.

That blue line is PEX, right? Unless you have an issue with critters chewing through the PEX, I'd stick with it. Is the white line just plain PE. PE gets brittle over time and has a habit of bursting. But you can find PEX in the same sizes if you look hard enough.

The "stainless" lines you find in most stores nowadays have a plastic exterior braid that is merely stainless in color. The line inside is vinyl, which is inferior to the above choices.

Your other option is to run it in copper. Copper tubing would fit in that plastic push-in connector too.

Why replace the plastic?

I have seen 50 year old installs working just fine.

Water pressure is, at the most, 60 PSI.
Your current install will handle that without a problem.

Yes, most are just plastic braided. I would just use theth percent of plastic thatyou have.

Got it. Much easier than I thought. Thanks!
