Question Full Hookup Camping

I wasn't sure how to search for this topic, so I am posting a new thread. My question is, when full hookup camping which we don't do much of, do you keep your waste valves closed and just empty occasionally, or leave them open the whole time?

Leave the black tank CLOSED until you need to empty it.

Otherwise you'll end up with what everyone here calls the "dry mountain of death" at the bottom of the potty drain.

Others we can/sometimes do leave open.

I leave them all closed and open them occasionally. Full tanks you get a good flow upon emptying

I leave everything closed...Both grey water valves and black water valves. This lets the black tank fill up and helps to clean it out better by having a "bigger push" of waste coming out of it. Having the grey tanks full helps in cleaning out the drain hose after draining the black tank. If the grey tank fills up before the black tank I drain some out of it then reclose the valve and let it fill back up for later black tank draining.

Best to leave them all closed...some will say its ok to leave your gray tanks open but the problem is that if you leave those open..when you come to empty your black tank, you want some gray water so you can rinse your sewer hose after dumping the black....we just leave them all closed and empty them as needed...depending on your usage you may find you are good for a few days and may only have to dump at the end of your stay.......whatever works for you...but never ever ever...did I say ever.. leave your black drain open.

All closed, unless we are staying 4 nights or longer with hookups. Then I close black, but leave grey for shower open until a couple days before leaving. That way we can shower without worrying about tanks. Otherwise it seems I end up going out in the dark to pull the valve when it backs up into the shower. But, I've got three daughters and we use lots of water when on hookups. They seem to understand being careful when not on hookups though

I also keep them closed until dumping.
Great choice for "Living within my means" and camping for one...

I keep both closed unless we are doing laundry. Some keep the gray open but I'm worried that if the CG sewer were to back up I could end up with a mess in the MH. I don't know if there is a check valve in the system or not but I'm not taking the chance.
