PLUMBING
The sewer line must be securely capped during self-
containment use to prevent leakage of waste material
onto the ground or pavement.
Do not pull the holding tank gate valve open, or operate
the electric dump valve switch (if equipped) when the
protective cap is installed on the pipe. Always drain the
tank into an acceptable sewer inlet or dump station.
WARNING
!
Holding tanks are an enclosed sewer system and
must be drained into an approved dump station. Both
black and gray water holding tanks must be drained
and rinsed thoroughly on a regular basis in order to
prevent the accumulation of harmful or toxic materials.
WARNING
!
When routing the sewer or macerator hose, do not
place on or near the Oasis, generator or engine
exhaust pipes. Otherwise, damage may occur.
CAUTION
!
Use only approved RV odor-controlling chemicals in
the holding tanks. Products containing ammonia and
petroleum will damage the ABS plastic holding tanks
and seals.
Be careful not to spill the chemical on your hands,
clothing, or the carpet as it may cause a permanent
stain.
IMPORTANT
!
Waste Water Disposal
Both of the holding tanks terminate in a valve arrangement that permits draining each tank separately or together. The
valves that open to release the water are called gate valves. The blade that closed the opening in the sewer drain pipes is
connected to the T-handle to release the contents of the tank(s) when pulled.
During normal use, tank buildup may occur on the inside
of the tank. How quickly buildup occurs varies from user
to user and is affected by many factors such as water
hardness, the amount of solid waste, how easily the toilet
paper breaks down, how often the tank is dumped, and
how well the tank is flushed. When buildup occurs, it
may impair the tank sensor’s ability to read tank levels
properly. Preventive tank maintenance is recommended.
Both tanks should be rinsed after dumping and treated
with a waste tank additive to help break down and liquefy
solid waste and help reduce odors. This chemical is
readily available at any RV supply store.
How To Drain The Waste
Water Holding Tanks
The holding tanks should only be drained when they are
at least three-fourths full, to provide sufficient water to
allow the complete flushing of waste materials in the drain
lines and hose. If the tanks are not three-fourths full, add
enough water to allow for sufficient flushing. Whenever
possible, drain the holding tanks prior to traveling. The
carrying capacity of your unit will be reduced if water is
left in the black or gray tanks.
To empty the waste water tanks, follow the procedure
below, depending on the type of waste system your
coach uses. It is recommended to drain the black water
tank before the gray water tank. The holding tank valves
may be operated via a tank gate valve (t-handle) or an
electric dump valve switch (when equipped).
DRAINING THE WASTE WATER TANKS
ON A COACH WITH A STANDARD
GRAVITY DRAIN AND DUMP SYSTEM
1. Connect the adapter to the drain hose.
2. Unscrew the drain cap, and connect the hose with
the adapter to the drain fitting. Support the hose as
needed for optimal flow.
3. Open the gate valve all the way by pulling on the
T-handle. The tank will start to drain as soon as the
T-handle is pulled.
4. After you have drained the black water tank,
immediately drain the gray water tank, allowing the
water from the gray tank to wash the black water
residue from the drain lines and hose.
5. When both of the tanks are empty, flush them with
fresh water before you close the valves. Flush the
gray tanks by pouring a couple of gallons of water
into a sink drain. The drain outlet is engineered for
quick release of the drain hose adapter.
6. Always close the gate valves and secure the end cap
to prevent leakage while in transit.
7. Add a holding tank deodorant to help control the
odor and break down the solid waste.
