Open the black first and let drain totaly then shut and open the grey and let it drain fully . do not leave black tank dry tho you should always add a few gallons of water along with water softner crystals and laundry detergent. "geo-method"
You should have some type of gauge panel inside your unit that you have to push a button to see how full your tanks are .
With that being said do not rely on the guages to be very accurate .
use it as a guide only . As you camp more you find how long it takes to be "full"
