How to fix leak on 1/4 tube for humidifier
I seem to have some issues with this connection. Basically it's a valve going from 1/2 pex to 1/4 (I think?) tube which then goes to the humidifier.
When I turn the tap on, over time small droplets form at the connection point. I undid the connection and applied white pipe dope meant for threaded connections. I normally have good luck with that stuff vs teflon tape, for permanent connections.
Now, maybe I'm doing this wrong, there is a little ring inside, think a sphere that has it's top and bottom cut off. Does this ring go over the tube, or inside the tube? I put it over the tube, it fits very tightly, and the tube is cut flush with the end of the ring. Is this right? I can take it apart and post a pic if you're not sure what I mean.
It was ok all last year, though I installed it late in the winter. I did have issues with a leak at the start but I had managed to shove some teflon tape and it lasted the year.
Given the size of the leak, I'm almost tempted to just stick some silicone caulk up there, but I know that's not really the right way.
Posted pic of leak area, as well as overall setup, sometimes it helps to see the big picture.
