Porkchop, an edit to your comment about the shut off valves. Yes, the DRV units have individual shut off valves for all the water lines with one exception as follows.
We have the 1-1/2 bath unit, therefor two toilets. When one of the toilets leaked I immediately shut off the water. Guess what, now no water to either toilets. Lots of fun when your on the road and no place "TO GO".
Of course, if you RV you learn to survive and bounce with the road bumps.
