water leak on 3050S

[oldnewguy]

Under my motorhome i have a blue, red, and black plastic hoses . the black one drips water out very slowly. I know the red and blue are drain pipes to remove water from lines for winterizing the system. So what is the black one and should it drip water? 2013 sunseeker 3050S this unit is new to my dealership so they could not answer the question over the phone.I can not get it there until june and we are using the coach now.

It is the freshwater tank overflow? Many have the problem of syphon action when the tank is filled over maybe 1/2. The black hose should have a fine mesh screen attached to it to keep out small critters. If you overfill the tank, this small line keeps it from pressurizing.

Red and black should be hot / cold low point drains. Only other line I know of that would be sticking out underneath is the fresh water tank drain. Very possible that's what it is if it's dripping water. Easy to check that.
