It’s a pretty common complaint among RV owners — it takes forever to fill my fresh water tank and the water keeps “backing up” while filling.
This was a big problem for us. We have two 50 gallon fresh water tanks and it would take an hour to fill them. The Owner’s Manual warned of this and states to fill the tanks slowly with the water bib turned to a low volume. This was completely unacceptable.
I finally devised a solution that cost very little money and will not take much time for anyone to adopt.
