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.
