Waste Water Tank Draining
To empty waste water tank, remove outlet cap and
attach the sewer hose by pressing the hose bayonet
inlet fitting onto the outlet — rotating clockwise until it
feels solid and secure. Attach the outflow end of the
hose to the sewage station and orient hose so it will
completely drain. Pull the dump valve handle out and
wait until the tank is drained.
Close the dump valve and partially refill the tank with
clean water and repeat the process until clean. The
holding tank must be flushed out until all paper and
waste material is removed. Should solids accumulate,
close the dump valve, fill the tank about half full
with water, then tow the trailer for a few miles. The
turbulence caused within the tank will usually loosen
and suspend the solids so the tank can be drained.
Replace the dump outlet cap prior to traveling.
When you are in a park and connected to a sewer
station, keep the main holding tank dump valve closed,
and empty waste tank every few days or when it
becomes almost full. Only by sending a large volume
of liquid, all at once, through the main holding tank will
toilet paper and other solids completely wash away.
This practice will avoid the accumulation of solids in the
waste holding tank, which could lead to an unpleasant
cleaning job.
Draining the tanks as described will protect them from
freezing during storage. When traveling in sub-freezing
temperatures, use a winterizing solution designed for
RV use. Follow the directions on the container.
Waste Water Tank Flush
The trailer has a water hose connector specifically
for flushing the waste water tank. To use, hook up a
garden hose and turn it on. A spray head within the
tank will rinse the interior surface of the tank. The
dump valve should be closed for the first couple of
minutes. Once the tank is half full, turn the hose off,
pull the dump valve and release the water out in a
rush. Repeat as needed. The tank flush should be
used regularly or 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.
