How to remove brine tube?

[Dvid]

Struggling to figure out how to remove this black brine tube from the rear so I can clean the brine well. Do I

A. Push it in towards the well then pull it out or
B. Just pull it out?
C. Do something else?

Some versions have a screw nut that hols the tube in place, mine does not.

Thanks! I can't find a YouTube video for this and I searched the forums.

That looks like a push-to-connect fitting. You need to push in the ring to release it. Sometimes you need to push the pipe into the fitting while pushing the ring. They make a tool with a U-shaped end to aid pushing it in.

There are videos explaining it. I tried linking one but could not get it to work. Will try another one.
EDIT... not working either. Try searching using the phrase "remove push-to-connect fitting"

Ah, excellent. It was C, a combo. Will try and report back.
Thanks so much!
