Combining black and Gray
I know this has been discussed before but I wanted to be really clear on this issue/solution.
This weekend we camped without hookups. Which is fine and 4 of us were able to take showers and the gray filled up but not over. We were careful to make sure of this. Another day and this would have been an issue. Since the black was only at 1/3 it occurred to me that I could extend the gray tank capacity if I opened both valves and "shared" the tanks. I know there is a more permanent way to do this but opening both valves would serve the same purpose right?
Is this an Ok practice? Not sure why but I always felt weird about combining the 2 tanks. But I do know some higher end rigs only have one tank so it must be OK and a lot of you do this to help the gray flush the black when dumping. Is there any harm in letting my 2 tanks comingle? If not why do they even bother with 2 tanks instead of one?
There are traps in every sink that feeds the gray, and even some bathroom sinks feed the black. So why not just have one big tank?
