water in black tank

New to rv camping, but would like to know what everyone does to start using their black water tank...1st time out tank wouldn't drain as it plugged up due to water draining off and leaving solids in tank. I was told to add water first, if that's the case how much should I use...tank about 40 gals.

    Some people use as much as 5 gallons of water to start, but I usually start with a couple of gallons. I think the important thing is to use lots of water as you use the toilet. It never hurts to end with a full bowl of water after the last flush. Also, I let it get close to full before emptying the tank. If I have to empty early, I put several gallons of water into the tank before doing so.
