ok someone step in if I am not correct in this because I am a newbie.. I believe that every TT has them they are lines that run via your hot & cold water lines. My understanding of them is to open them when draining your system of water during winterizing so that all water will be out of the lines. Mine are located behind my water heater. ( Mine are red for hot water line/ white cold water line they don't all have these colors)there is also a similar one located near your fresh water tank to get all water out of it. when you de-winterize you can also open them to get any extra antifreeze out of the lines...
Let me say you may think you don't have them which I did too (and maybe you don't) but you will not see them unless you really get under your RV they are hidden well it took me a bit to locate mine and I had worked above the area that they are located in and never saw them...
You might look under the area of where you shower is located or I have read they can be located below your couch area.. good luck hope this helps..

Not to appear overly ignorant, but what do the low drains drain? I obviously don't have any in my Roo 233S, but am curious in case we upgrade.
