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?
Coleen, the working while RVing editor replies:
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.
