Over flow hoses for water lines?

[codfish]

Hello All,
We have a 2017 JF 23RB. There are 4 overflow hoses that exit the underside of the trailer. Two of them are for the fresh water overflow, but I don't know what the other two are for. The exit behind the rear wheel on the street side of the TT and they are Red and Blue. Any ideas what these are for?

Thanks in advance.

They are FW drain hoses and should have pull valves on it (inside)

Sounds like the hot/cold low point drains. There should be valves above inside the trailer usually mounted to the floor, they usually have a t handle, pull up to open.

Cool. I figured they were something like that. I think I know where to look...wish they had shown me on my walk through.


Thank you!
