Red Sea downflow leak

[v0rt3x911]

Hello all,

I have a slow leak occurring on my downflow pipe in my Red Sea XL200. Water pools above my gate valve.

Any idea how I can fix this?

can you circle the part of the fitting it is leaking from. You have a glued section, a threaded section and a section that has an o-ring
