Gray tank capacity - two seperate tanks

no-logic wrote:
We have a 2012 Palomino TT with a gray water capacity of 74 gallons which is great. The problem is it is two separate tanks - one bathroom and one galley. Our issue is that we fill the bathroom tank in 2-3 days between my wife and I taking showers, etc. The galley tank is used very little since we always do our dishes outside with plastic tubs. We have been using buckets to drain some of the bathroom gray water and then dump it into the galley sink. But what I would like to do is either plumb the tanks together somehow or use some sort of a pump system to run the bathroom gray into the galley tank. I'd like to make the process of transferring the water as easy as possible. Has anyone else tackled this issue and, if so, what did you do? Thanks.

Some have added a valve at the terminal where you attach your hose for dumping, which gives you control there. That allows you to leave both grey tank valves open so they can "share."

Some rigs have two dump locations though, so that wouldn't work. Also note that galley grey is nasty stuff compared with the shower/sink grey water so you will get nasty grey in both tanks that way.
