Whenever possible, dump the holding tanks
before traveling. The holding tank outlet is set
up to be used with are movable fitting that locks
onto the outlet with a clockwise twist. The
sewer drain hose is clamped on this fitting
when you need to drain the holding tanks.
When you are operating self-contained, or you
store the camper, install the protective cap in
place of the removable hose.
When you want to drain the holding tanks:
1. Attach the sewer hose to the dump outlet.
2. Extend the hose and insert the hose end
into the sewer or dump station inlet,
pushing it firmly into the opening to be
secure. In some cases, adapters may be
necessary between the hose and inlet.
3. Arrange the sewer hose so it slopes evenly
and is supported to maintain the slope.
4. Dump the black water holding tank first.
5. Allow enough time for the tank to drain
completely. Rinse and flush the tank and
drain hose through the toilet with a bucket
of water or a hose.
6. When the tank flow stops, close the valve.
7. Open the grey water holding tank. Repeat
steps 4 through 6. This tank is dumped last
to aid in flushing the outlet and drain hose.
8. Remove the sewer hose and replace the
outlet cap.
9. Rinse out the sewer hose with fresh water
and remove the sewer hose from the dump
station.
10. Replace sewer or dump station cover(s).
11. Store the sewer hose.
NOTE: To facilitate draining, the RV should
be slightly higher in the front and raise the
passenger side of the trailer to drain towards the
driver’s side. If you are parked at a site with a
sewer hookup, keep the black water valve
closed to allow the waste level to build up. The
outlet will probably clog if you leave the valve
open continually. Run enough water into the
tank to cover the bottom. This will aid the
breakup of solid wastes. The gray water valve
may be left open.
HOLDING TANK CARE/MAINTENANCE
Since holding tanks don’t rely on any
sophisticated mechanical devices for their
operation, they are virtually trouble-free. The
most common problem is also an unpleasant
one, clogging. You can minimize chances of
clogging by keeping the following
considerations in mind:
• Keep the black water tank valve closed. Be sure
to cover the tank bottom with water after
dumping.
• Movement while driving will help liquefy the
solids.
• Use only toilet tissue formulated for use in septic
tank or RV sanitation systems.
• Keep both valves closed, and the drain cap tightly
in place when using the system on the road.
• Use only cleaners that are approved for use in
septic tank or RV sanitation systems.
• Use a special holding tank deodorant chemical
approved for septic tank systems in the black and
gray water holding tanks. These chemicals aid the
breakdown of waste and make the system much
more pleasant to use.
• Do not put facial tissue, paper, grease, ethylene
glycol-based or other automotive antifreeze,
sanitary napkins or household toilet cleaners in
the holding tanks.
• Do not put anything solid in either tank that could
scratch or puncture the tank.
If the drain system does get clogged:
Use a hand-operated probe to loosen stubborn
accumulations. Seriously clogged P-traps may
require disassembly. Be careful not to over
tighten when reassembling. Do not use harsh
household drain cleaners. Do not use motorized
drain augers. Sometimes the holding tank valve
will get clogged. In this case, a hand-operated
auger may be necessary. Be ready to close the
valve quickly once the clog is cleared. If the
seal gets damaged, it must be replaced.
