NOTE: DO NOT OPEN BOTH VALVES AT
ONCE. Do not open the Gray Waste Tank
Drain valve until the black tank is
drained and Black Waste Tank Drain
valve is closed to avoid sewage back-up
into gray tank. Gray water also rinses
any black water solids from the sewage
drain hose.

hold the Waste Pump switch (located in the
water service center). Release the Waste
Pump switch and close the Gray Waste Tank
Drain valve as soon as the tank is empty.
