Today we're going to be taking a look at the Valterra 12 gallon RV freshwater tank. It's a lightweight completely algae free black ABS plastic construction. Tasteless, odorless, and non toxic design. You don't ever have to worry about this tank rusting or corroding. It's a one piece extruded construction, which eliminates the possibility of leakage. It's a really nice design of the unit.
It's a universal design, so it allows for an easy installation. It does feature three 3/8 inch thread fitting inserts on each end. The one on this end is the open fitting. The other two are not open, so they just have the threads but it does have a back plate in there. You going to have 3 of those, located on each end of the tank. A few measurements to go over with you real quick.
Starting with the overall length. It's going to measure about 24 inches long. About 16 inches tall, and if we take a width measurement it's going to measure about 8 inches wide. Again the capacity is 12 gallons, which is 45 liters. On the sticker that's on the tank, it's going to go through just some helpful information. It's also going to go through sanitation process and instructions.
That's going to do it for today's look at the Valterra 12 gallon RV freshwater tank.

Theyre in now, for about two weeks and everything is just what I expected. Wish I could add a photo or two. I made a couple of modifications to them for the purpose cleaning the tanks down the road.

Initially there was a plastic taste to the water, after rinsing with baking soda it seems to have taken care of the problem. Well made tank

The RV water tank works Just perfect. One heads up to all purchasing a tank - remember it needs a vent coming off the front top of the tank or it will burst when you add water - I learned the hard way.
