why the red and blue redwater hoses In tcontrol center of the basement compartment

[jbeliera]

I have looked in everything I have on my systems with this 2014 Montana 3625re coach and don't know for the life of me what this hot and cold lines are supposed to be used for...they have a petcock so I assume it is used teto drain hot and cold water from some where but why

I would assume it is your low point drains. That’s what mine are

The low point drains are used when draining the entire RV water system, except the water heater and fresh water holding tank. Generally used when you are getting ready to winterize.

thanks

i was puzzled why everything else is well labeled and or defined in that compartment but not theses two lines… i knew it was for water but from where and why …my other coach (Laredo) had them in the belly of the trailer… i have had two Keystone fivers now and this 3625 re is certainly more intricate. thank you for your responses
