How To Plumb Rv Holding Tanks? The Best Explanation

To get by with one fill spout, both tanks have to be on the same level and height. You will need to connect a water line at the bottom of each tank and a vent line at the top of the other tank. This will allow the water to flow from one tank to the next.

You’ll also want to make sure you have enough space between the two tanks so that you can fill them both with water. If you don’t have the space, you’ll have to fill both tanks at once, which can be a bit of a hassle.
