Thanks for quick response.

I have a separate grey tank forward for sink and shower. Kitchen and Half bath share second gray tank. Separate Black tank for 1/2 bath so the black forward is only toilet, vent, and drain.

Is it possible that the vent pipe extends too far down (as in not adjusted properly before securing) into tank? If so it would allow drain but once level is high enough it would be blocked.
