Conceivable or Fantasy?

[SGilbert]

Please don't laugh too loud!!

Be it known that we do not use the shower at all. Also very little, if at all, use of the kitchen sink.
We carry bottled water for drinking and Keurig coffee maker.

Consequently, the only faucet water we use is rinsing after tooth brushing and hand washing.
That being in the bathroom's sink. The sink in there, in Thor's infinite wisdom, drains into the black tank.

The result is that the black tank needs emptying after 4-5 days, the gray tank almost not at all!

Here is the hairbrained, or logical, idea:

Leave both dump valves open, and make doubly sure the end cap is totally tight and leak proof.
That would mean the black tank would equalize with the gray tank by their respective drain pipes.

After you are done laughing, is this reasonable, doable, and practical?

No, the gray tank usually has a small pipe and you don't want solids etc getting in there. The wisdom is the efficiency of not running pipe all over to get it into the gray tank. My 2004 Minnie Winnie is the same. Why not wash your hands and brush your teeth in the kitchen sink? That should not be that much water anyways. On out trip out west we started saving the dishwater and using it to flush the toilet and reduced our water usage tremendously.

4 or 5 days? Learn water conservation.

Most people I hang with use a plastic cup for water to brush teeth. They put a salad bowl in the sink and use the water they clean up with to help flush the head.

Me? I use My recycled jar to brush, I do that job by a tree. Wash up the same way, out side. Then again I only have plumbing to make RO water. No holding tanks.

No!

I’m caught up on the first line,”we do not use the shower “. That’s all we use in the shower in the rig.
Maybe it can be really plumbed. Maybe there is room to add a second gray tank. Seems strange.
