Those hot/cold low point drain valves are not always easily seen...., I have to remove a bottom drawer in my kitchen to see/get at mine.
The valves are usually straight above the the actual drain tubes inside the TT, so I would use that as a starting point. They may be behind a panel that has some screws on it, etc.
