Drainage P-Traps; Holding Tanks; Emptying Holding Tanks - Gulf Stream Travel Trailer Owner's Manual

separate BLACK WATER HOLDING TANK. Some models may have a second GRAY WATER HOLDING TANK to
accommodate various floorplans and features. Which tank each sink drains into may vary from one model to another.
The drainage system also includes vents that carry odors caused by drain water and waste out of the RV, while also
equalizing air pressure. Drain clean outs are provided to clean lines between fixtures and holding tanks.

DRAINAGE P-TRAPS

By code, all drains are equipped with P-traps to keep holding tank odors from entering the vehicle. If you detect a
foul odor, which you believe is from your holding tanks, add water to all drains to ensure that your P-traps water hasn't
evaporated from long term storage. Places to add water include the Kitchen sink, Bathroom sink, shower/tub, wet bar
sink, and the washer/dryer drain.

HOLDING TANKS

Your unit has a GRAY WATER HOLDING TANK and a BLACK WATER HOLDING TANK. The tanks should be
emptied frequently, or as indicated on the monitor panel. The tanks should always be emptied at a special DUMPING
STATION. Most campgrounds and highway rest stops and many gasoline stations are equipped with proper
DUMPING STATIONS.
NOTE: MOST STATES HAVE LAWS PROHIBITING EMPTYING SEWAGE ANYWHERE BUT AN
APPROVED DUMPING STATION. THIS INCLUDES BOTH, GRAY AND BLACK WATER.
While camping, it is a normal practice to leave your GRAY WATER HOLDING TANK valve open if your campsite is
equipped with sewer hook-up. NEVER leave the BLACK WATER TANK valve open while using the coach. Since the
system utilizes gravity to empty, the BLACK WATER TANK will not drain properly unless is has sufficient liquid to help
drain out the solids. On some models the bath lav sink drains into the black holding tank to assist with flushing. Some
models may also have the shower draining into the black holding tank.
On models equipped with two gray holding tanks, you must use the dump lever for each tank to empty its contents.
Pulling the dump lever for one tank WILL NOT empty the other. Each holding tank fluid level is represented on the
monitor panel.

EMPTYING HOLDING TANKS

WARNING:
To empty the holding tanks, be certain that your RV
is level since this process depends upon gravity.
Remove the sewage drain hose from its storage location.
Remove the cap from the termination outlet and connect
the drain hose (FIG. 15).
NOTE: DRAIN THE TOILET (BLACK) HOLDING
TANK FIRST.
To drain either holding tank, pull out the
TERMINATION VALVE (FIG. 15) by pulling out the
dump valve slide handle. Close the valve after the tank
has drained. Flush or pour about two gallons of
water through the toilet when emptying the black tank
and drain again. This flushes the tank and helps
