Black tank flush question

[tmsbandman]

My 365 SAQB has two black thanks. There is a connection on the panel for black tank flush. Does this flush both of them, or only the front one? I have only had 'er out once (bought it last summer) and flushed the tanks after.... or so I thought.

Today I replaced the water filter with a GE unit. Ran the water for 15 minutes to flush the new filter, then was going to let the gray water out in my yard (tank was empty before). I accidentally pulled the (rear) black tank release instead, and a bit of sewage came out. So… Apparently I did not get my tank flashed properly at the end of the last trip. Please advise.

Just the front.

We'll crap (literally). So I need one of those clear elbows with the hose attachment for the back, I guess. Thanks for the info.

We found that our 2nd Black tank flush (as labeled up in the front compartment), actually was a flush for the Galley.

It is amazing to me how hard it is to get everything out of the tank. I've decided it is impossible to get it back to "pristine"....
