Gray water recycling idea
Our LiteHouse doesn't have a gray water tank; just a hose fitting for the drain on the outside. At first, I used a 5 gallon bucket but then I came up with what seems a better idea.
I'm a bit of a gardner and usually have a few plants in gallon pots outside. I pick a hardy looking suspect and bring it along in the back of the TV. When we set up, I put the plant on the ground next to the gray water outlet, connect a short hose to the drain fitting, and lay the end on the plant.
This seems to work well for the small amount of dish washing, etc. that we do in the sink and so far, no complaints from any of the campgrounds.
