2017 Alante 26X Low Point Drains

[stustoner]

Good morning, all! Hope all are safe out there! There are 4 low point drains in the wet bay of our Alante. Can someone tell me, from left to right, what they drain? I assume that the first red tube drains the hot water side and the other 3 blue tubes drain various cold side systems, but which does which? The plumbing schematic is no help as it only shows 3 drain lines. I can imagine that one drains the cold side and another drains the fresh water tank, but then there is the fourth one?.
TIA
Stay safe out there!

I don't know your RV specifically but you would need a overflow/vent tube for the FW tank I believe. My two trailers have one. Some have run the vent tube to the water inlet opening.

We have 4 on our 2020 Alante as well. Lines 1,3,and 4 drain our water lines. The second one(blue) is the fresh water tank drain.

On my 2020 Altante Class A the hot water tank did NOT drain via the low point drains. Even with the faucets all open. I had to unscrew the drain plug on the water heater and POP the relief valve

If you have a tank water heater that's the way they all work. To winterize you open the tank drain otherwise the tank holds water.
