So, I should keep the blackwater tank closed even when we have sewer hookups? And then simply open the valve and dump it every so often while camping?
Yes.
If you leave it open all the time, the liquids will drain out continually and leave a big solid pile. If the tank is full when you open the valve, there is enough flow to carry out most of the solids. I recommend you dump only when close to full, and then re-fill the tank with clean water, through a hose or flush valve, and dump again.
Also, never leave the tank totally dry...add at least a couple of gallons of water so the bottom is covered.
