Water Systems
 

Here is a website with some good info about water systems in RV's.

Water, Water, Everywhere!

Good find, very useful information for the RV beginner and the experienced RV person.

No, the black water holding tank is not concrete like a home style septic system. It is plastic like the gray water tank. Only difference is the contents. The black water tank is not a septic system. It is only a storage tank that holds the waste until you can dump the tank at a campground.

This may be a dumb question, but where did you get the idea of the black tank be made of concrete? I don't think the article that i linked mentioned anything like that. Or am I missing something here?
