Or close gray a little while before dumping black, if we are staying a while.
We have 5 plus campers usually too!

why would anyone leave black open? You would end up with a "pile" in the bottom of your tank as there is no chemicals and water to break everything down.

I hold the grey water for the last day or so to have plenty to rinse hose after dumping black

Keep everything closed until needed. Black valve is seeping so goes to dealer tomorrow. (IM NOT MESSING WITH THAT CRAP!). Lol!

Hook up hose once needed, and then dump black, kitchen, and bath. When not dumping all valves stay closed.

The grey tanks are another story. On short 2 or 3 day camping trips both grey tanks stay closed until ready to dump. When we're at one location for an extended period of time, as we were in Gulf Shores, I leave the shower tank open and the kitchen tank closed. When I dump the black water I follow that with a 15 minute black tank flush and then drain the kitchen tank.

Because my galley valve is located under the living room slide I have installed a valve at the "Y" to allow me to keep the water in the tank. I have found that if you keep the gray water valve open you will get a smell from your vent pipe when a neighbour dumps their tanks. Plus by using chemical in your tanks and leaving the valves closed you help keep the seals lubricated.

Black and grey tanks remain closed until full, or time to pack up and leave.

I usually keep the grey shower open and the other grey and black closed.

Both grey and the black tank remain closed until they are showing about 3/4 and then opened. If we move first, always empty all of the tanks.

All valves closed until tanks are at least 2/3 full or we are ready to leave, then it's black tank first always, followed by a good black tank rinse, galley and lavatory. Most of the time the lavatory will need draining 2 to 1 or more over the galley because of the shower use. Just DW and I so it's pretty easy to keep under control.
