Diverted valve keeps leaking

[Feralfarms]

Update: so I found the source of the leak. It appeared to be coming from the elbow, upon further inspection it was not. For those saying don’t use Teflon tape, the tape wasn’t the problem, the tape was applied prior to me, most likely at factory or after the first time it was repaired by the dealer. I did find however that the o ring on the underside of the body was infact highly corroded. Replaced with a new one, and stress tested, no more leak. Photo attached for location and reference.

For those that said to check o rings and seals thank you for pointing me in the right direction.
