The best way to get this resolved in a new to you camper is to empty both grey tanks. Close them both and add 5 gallons of water to your kitchen sink drain.

Pull the dump lever for tank 1. If you get flow, You know that it is your kitchen tank....forever. The other will be bath & Bath sink drain. I put a sticker on mine. Also make sure the inside indicator and pull handle marking agree.

My two 30 gallon gray tanks have the drain pipes connected together before the main dump valve. So when one gets close to full and the other is empty I just open both dump valves thereby connecting them together which increases the capacity to 60 gallons....

Thanks Norty. Tomorrow I dump, so gonna check readings after I pull first valve, (I know which valve goes to the kitchen and the other to bathroom, due to proximity.)

Hey, thatís a good idea. They are connected.
(Only one sewer outlet)

I installed a gate valve at the sewer outlet that enabled me to open both gray tanks at the same time to equalize the contents.

I have the extra gate valve, too. Definitely makes things much easier.

Today I verified: tank #1 is the bathroom sink and shower.
