We use Reliance Aqua-Tainers in our water system in the van and it has served us very well over the last 2 years in the van. It gives us a lot of flexibility when we are camping off grid and fill up water wherever we can. Each jug can hold 7 gallons of water and with 3 of them, we can carry 21 gallons of fresh water which allow us to stay off grid for about a week in between refills.
One of the inconveniences however is the need to swap jugs when one runs dry. Sometimes we are staying at a place with readily accessible water for refill. Instead of just simply topping it off, we need to remove the jug and swap the empty one for a full one. It isn’t that big of a deal but I have often wished there was an easy way to just top off the attached jug without the juggling act.
So this is why I decided to make this modification. I found an ABS bulkhead fitting that allowed me to install a second opening that wouldn’t leak. By using a rubber seal and a brass pipe cap, I was able to add an easy way to fill the water jug while it is connected to the water system.
Here are the parts I used to make this mod with my 7-gallon Reliance Aqua-Tainer. This would potentially work with just about any water jug as long as it has a flat surface near the top.

Here is a video that shows you how we installed these parts into the Reliance Aqua-Tainer jugs. You can also see the two use cases of how we utilize this mod in our every day lives.
I hope this helps someone out there also using jugs in their water system. I am very happy to have done this mod. Every little conveniences help improve our quality of lives on the road.
