What drain is this?

[TeamRAB]

I stepped outside this morning to enjoy my coffee and I heard a drip.

I know the one in the foreground is my low point drain for my fresh water tank, but I can’t figure out the circled one.

Need to post the make and model and maybe a clearer picture.
My 195RB has a fresh water drain under the tank and two more drains for hot and cold near the rear under the how water heater area. It is located between the kitchen and bath so it can drain the pipes in that area.

All I see circled is the power post...

Here it is from the other side. It is located near the front of the trailer, on the driver’s side.

The trailer is a 2018 Whitehawk 29RE.

That may be the overflow for the fresh water tank. Does your tank show "full" on the monitor panel?

[TeamRAB]

There’s maybe 10 gallons of water in the tank, but I’ll drain it and see if it stops.

That amount of water won't exit the overflow unless your TT is extremely out of level, which I doubt. The reason for my question is sometimes when hooked up to city water, the backflow preventer on the water pump can fail, and the water tank will slowly fill up from the city water pressure.

What is directly above that hose, on the inside of your TT?

Looks like it’s above the bedroom closet, which I believe is above the fresh water tank.

Looking at your floorplan, it's seems too far away from any plumbing to be anything else but the overflow.

Fridge and A/C both can have drains. Are they close?
