Mystery leak.
This is my very first post to the forum and I have appreciated reading all of the helpful comments. Thank you for letting me join. I have a 2000 National RV Sea Breeze. I have just begun using it...

You have a 20 year old Motorhome that who knows what has been modified in that 20 years.
1. The Plumbing on a National is simple like most RV's.
2. Since your problem is NOT when on Water Pump, That means you probably connected to a Tank Flush Inlet that was added to the Gray tank. Nationals back in 2000 did not have a Gray Flush and a Black Flush. usually just a Black flush.
3. In 20 years it is possible that someone added a extra valve system to connect to the tank flushes by just switching a valve and not having to unhook the City Water fill hose and then connect to the Flush connection. Doug
