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.
Where is the fresh water tank? Second is, where are the valves for winterizing the plumbing system? Not just the water heater. Someplace you have to turn a valve to suck RV antifreeze into the system. The fresh water drain valve is close by most often.
