NON-POTABLE/GREY WATER SERVICING
The optional non-potable and grey water tanks are installed in the bottom
of the vanity. A pump is used to pump water to the faucet. The non-
potable water tank has a volume of 0.58 gallons. The grey water tank has
a volume of 1.0 gallons to prevent a water overflow. Quick-disconnect
fittings are installed in the back of the tanks. The non-potable and grey
