RV Water Tanks
(A motorhomer owner asks...)
We don't use our RV water tanks. Since I've owned my motorhome, I have never put water in my holding tanks. I shut the valves off to my tanks. We don't go boondocking, and we always find places for total hook ups. We carry drinking water. Is there a problem with this, or will there be a problem later on?

You mean your fresh water holding tanks, right?
If the tanks have always been dry, I don't know of any problems that you should have with them.
If the manufacturer or dealer put water in them to test for leaks, or if a previous owner used them, there could be a problem. It's often impossible to get all of the water completely out. If there's a small amount of water remaining in them, you could have something growing, such as unfriendly bacteria.
If I was buying a new motorhome where they had put water in the RV water tanks, and I didn't want to use them, I'd add a disinfectant. I'd mix ordinary, unscented chlorine bleach with water, put it in the RV water tanks, and then drain out as much of it as possible. Go to the RV Life and Travel blog.
