Black Water Tank Flush
The trailer has a water hose connector specifically
for flushing the Black Water Tank. To use, hook up a
garden hose and turn it on. Within the tank, a head with
multiple holes will spray the interior surface of the tank.
Once the tank is about half full, turn the garden hose
off and flush the water from the tank using the dump
valve. The valve should be closed for the first couple of
minutes, and then opened to let the water out in a rush.
Repeat as needed.
It is recommended the tank flush be used on a regular
basis or the holes on the spray head may become
clogged�
Drain Systems Cleaning
The only cleaning agents that can be used without
causing harm to the system are household ammonia
and tri-sodium phosphate in small quantities. Do not
use any product that contains any portion of petroleum
distillates. This type of product will attack the rubber
seals of your toilet and dump valve. Also, do not use
any dish detergent or abrasive cleaners. All products
should be marked as approved for ABS drainage
systems.
Winterizing and Storage
When storing your trailer for short or long periods,
use the same precautions as you would in your own
home in regard to perishables, ventilation, and rain
protection. In addition, for prolonged storage periods,
flush all the drain lines and the holding tanks. Also
drain the entire water system including the water heater
and the water storage tank. Instructions for draining the
water system are explained in the following paragraphs
on winterizing�
The main consideration in winterizing your trailer is
to guard against freeze damage to the fresh water
system lines, tank, and pump; the waste drain system
including the traps and tanks; the water heater; and the
batteries.
To completely winterize your trailer follow this
procedure:
1� Level the trailer from side to side and front to rear.
Open all faucets.
2� Turn the water pump switch to the ON position to
expel water from the storage tank
3� Open all drain valves including drain plug or valve
on water heater and exterior water service valve.
4� While the water is draining from the system, open
and flush the toilet-flushing valve. Depress hand
spray lever while holding the spray head down
inside the bowl. Depress hand spray thumb button
on the telephone shower head while holding down
inside the tub and drain all water from the flexible
hose. Unscrew the heads on both spray units and
store.
5� Turn the pump switch OFF after all water has been
removed from the storage tank.
6� Disconnect outlet hose from water pump.
7� Disconnect the water pump inlet connection and
turn the pump on until all the water is expelled.
This water, about 1/2 cup, can be caught in a towel
or rag�
8� Lower the front of the trailer as far as the jack will
allow until water ceases to drain, and then crank
the jack up as high as it will go and allow any
remaining water to drain out.
9� After the water has stopped running from the drain
lines, apply 50 lb. of air pressure at the city water
inlet. An air-to-city water adapter is available from
your dealer’s RV accessory store. Be sure the
toilet valve, all drain valves, and faucets are open,
and pump outlet hose is disconnected. This can
be done at a service station and will force any
remaining water from the water heater and remove
any water that may be trapped in low areas.
10� Pour a cup of approved non-toxic RV antifreeze
that has been listed by a recognized testing
authority such as Underwriter Lab into the lavatory,
sink, and tub drains to prevent trap freeze-up.
11� Be sure to open the waste-holding tank dump
valves, and drain and flush the tanks thoroughly
(this is very important as the sewage in the tanks,
if frozen, could seriously damage the tanks) � Plan
ahead and have this done at a dump station.
