Grey Water Tank or Grey Water System Leaking

[RobertLang]

I have a older but low mileage 2002 Granite Ridge. On the second night of a three day inaugural trip, I noticed that grey water was leaking into the tray under the water tanks on the driver side of the camper. This is where we store the electrical hookup cable, access the third, water pump turn-on, button; and have the black and grey water flush valves.

Dumping four gallons of grey water into a five-gallon bucket stopped the overflow. And, yes, I am certain that the water was grey water and not the 5hittee sewage waste water.

Next day dumped both tanks at dump station.

Day after that and at home, I filled the grey water tank by running the sink, until, grey water overflows.

I cannot see any connectors, but then, I DO NOT KNOW WHERE TO LOOK or HOW TO ACCESS THE grey-water pipes to gray water holding tank area. I see some references to remove the plumbing panel, BUT WHERE IS THAT?

Thank you in advance.
