RO line keeps popping out of float switch

I've never had issues with the nut but yeah mine have all had that inner piece of plastic too.

superglue would fix it permanently!

Yah I considered superglue last time but went with silicone because it's easier to get off if I ever needed to. The RO line comes in through one of the small screw cap holes on the top of the rain barrel I use to store water, but that hole it too small to fit the float switch through, so if I super glued it and I ever needed to take the lid off I'd have to cut the RO line and probably toss the float switch. However, I'm going to be tossing this float switch now anyway. Seriously it looks as though it was running unrestricted all weekend. Long enough to make the water in the 55 gallon barrel (which sits on a heated concrete floor) the temperature of Calgary tap water. That's 300 gallons of water that (thank god) mostly went down the floor drain in the utility room, and probably 900 gallons of total wasted water. Our utility bill is going to be nuts again this month.

I'm going to do some checking and try and find a better float switch. My tank has always rested on thin ice, and I don't need to give my better half any more excuses to want it gone.

Found the one I have, it's this one exactly:

The other one that J&L sells will require me to drill a hole in the side of my barrel (it fits like a bulkhead), and the water line would attach on the outside of a barrel. It looks like it has the same style of compression fitting though. Not sure if that's even worse though, as if the water line popped out, the water would be going right on to the floor. When it pops off inside the barrel, sure it makes the barrel overflow, but at least some of that water ends up being used to top off the tank so it's not overflowing at the full rate of the RO unit.

ETA, sorry didn't copy that link right. I have the Eshopps valve

I have the one you have to drill into the garbage can. You can definitely not pull it out once the nut is tightened and I only hand tighten it.

I use the Kent, have for 12 years and the line never popped off.

Not just the good ones use a insert, they just include it.
Any time that you use a plastic line in a compression fitting, you need an insert.
now JG fittings have a little safety factor, considering the bite.
In any pressure application, always use an insert fitting, they should be available at rona, home depot, etc....

For my experience there is a sleeve that gets inserted into the ro line that keeps the line rigid enough to for a seal. I'm guessing the sleeve fell out the first time this happened. A quick stop at any hardware store should fix it.
