PLUMBING
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.
5. Open the Gray Waste Tank Drain valve and
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.
NOTE: Sound of Waste Pump will change
significantly when tank is empty.
6. Add an odor control chemical to the sewage
holding tank through the toilet. These
chemicals are available at most RV stores.
7. Rinse sewage drain hose thoroughly with
water and stow.
NOTE: We recommend that you dump all
holding tanks before traveling to avoid
carrying unnecessary weight.
Using On-Site Sewer Hook-Ups
The sewage drain hose may remain attached to
the sewage drain outlet while the motorhome is
parked and connected to an on-site sewage hook-
up.
