Sewer Connection; Draining The Tanks - SAFARI Trek 2002 Owner's Manual

Clean the tanks after every trip. The grey water tank generally requires only an occasional
rinsing. Do this by running clean water from the shower or galley sink to fill and then
drain the tank. If an odor develops in the grey water system, fill the tank with a solution
of water and baking soda. Let the solution sit for at least an hour and then drain it.
The black tank requires more attention. Each time your tanks are dumped, flush the black
tank for three to five minutes with the holding tank valves open. For details on flushing
your holding tanks, please see page 5-5 in this section of the manual. After every trip, fill
the tank with clean water and drive the coach for several miles. The driving agitates the
water and helps dissolve the remaining solids. Then drain the tank again.
If your tanks or plumbing lines ever sustain damage, take your coach to an approved
service center. It is possible to repair tanks and lines without removing the tanks from
the coach.

The tanks are drained through a single fitting located below the service center. The opera-
tion requires a flex hose that is supplied with your coach. Cover the drain coupling with
the cap when the hose is not in place.
There are many publications that list dumping stations where you can empty your tanks.
Most state and commercial campgrounds and many service stations have a dumping station.

Draining The Tanks

Empty the tanks, as you would normally, at a dump station. The grey water holding tanks
can be flushed by turning on your faucets. One method to rinse both black and grey
holding tanks is to fill them at least 1/2 full with clean water and one cup Trisodium
Phosphate. Drive the vehicle a few miles to agitate and dissolve any residual solids and
then drain the tanks completely. The black water holding tank should be cleaned by
flushing it out with a garden hose attached to a rinsing wand, which may be purchased
through most RV accessory or service facilities. (Do not use your fresh water supply hose
for this purpose.) For best results, remain connected to a sewer dump station, as you may
need to drain the tank during this process, and once the tank and sensors are clean. Care
should be taken to thoroughly wash down the sides of the tank, as the fluid level senders
must free of build up and debris, to offer optimum performance.
