Identifying water lines

My A122 has two lines under the sink with T connectors, red and blue.
I always use city water so what position should the T connectors be set in? In-line or T-d off? Are they set differently when using portable water tank with pump ?

**now I see another post about pulling up on the T's. So are these primarily to drain/winterize water lines and thus not related to whether I use the water pump vs city water?**
I live in FL so won't be winterizing anything !

If you have valves on your Hot and cold water lines under the sink, I'm guessing they are low point drains...and if so..u should leave them in line unless you are wanting to drain the lines.

Our last travel trailer was set up that way.

Yes, those are Low Point Water Drains. They should be closed when in use, opened to drain the water lines. They are pull up to open to drain, push down to close to run water thru lines. On my unit, I sometimes have to twist the T- handles as I close them to seal tight. Good Luck with the new camper.
