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 out 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 exterior water
service valve, if applicable.
4� While the water is draining from the system, open
and flush the toilet-flushing valve. 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. Turn the
pump on until all the water is expelled. This water,
about 1/2 cup, can be caught in a towel or rag.
Reconnect hose.
7� Lower the front of the trailer as far as the jack
will allow until water ceases to drain, then crank
the jack up as high as it will go and allow any
remaining water to drain out.
8� 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 the 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.
