Clear drain hose ..

Is the clear plastic hose under the back of the 400 a high pressure overflow?

None of the drains are really "high pressure."  Just below the Alde compartment there are four drains--the low point drains for the hot and cold water lines and drains for the hot and cold Alde relief valves.  Those last two might be considered high pressure since they work like the pop-off valve on your water heater at home.  Although I'm not sure just how a cold water (input) line might become pressurized enough to need a relief valve.

Farther under the trailer  there is a clear hose like you would see coming out the cool cat. As a matter of fact that’s what I thought it was. Until today at a campground. After hooking up my water the drain tube ran like a faucet. I realized I didn’t have my back flow on the hose. After putting it on, the plastic drain stopped flowing. And I know the pressure in this place is really strong..So I need to find my paper work or call NuCamp.
