2003 Jayco Granite Ridge fresh water tank does not seem to drain completely. Is there a dedicated drain for that tank other than the lowe point drains? Thanks for any help you can give.
Can't speak specifically to the Jayco unit, but there sometimes are. My Salem Hemisphere has a drain immediately below the fresh water tank with a quarter turn petcock on it, but many don't. You don't indicate which model you have, but here's a link to the owner's manual for 2003 Granite Ridge. It has sanitization procedures that should show their recommended way to drain the tank.
