Sewer question

[bwinter1946]

I am not sure how your Bird is plumbed but I do know it is not uncommon on Birds
for the bathroom sink and/or shower to drain into the black tank. I personnally
think that can be good for two reasons:

1. The black tank could use more liquid to "flow" better when being drained.

2. It helps balance the flow between the back and gray tanks.

On my old coach the gray would fill in three days but the black could take two
weeks and would be "ripe" long before it was full.
