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 attacks the rubber
seats of your toilet and dump valve. Also, do not use any dish detergent or abrasive
cleaners.
All products should be marked approved for ABS drainage systems.
When winterizing the drain system use only RV approved antifreeze sold through your
dealer or RV supplier.

The RV toilet in your Airstream is a design that has been used for many years. There are
two pedals. The large pedal opens and closes the slide mechanism, and the smaller
pedal opens and closes a water valve.
In normal use, when you are hooked up to city water, both pedals are depressed
together. This dumps the sewage and fresh water and flushes down the side of the
bowl. Water will continue to run into the bowl for a short time after the pedals are
released.
When you wish to conserve water hold the hand-spray head over the bowl and hold
down the thumb-operated lever. Now when you depress the pedal all the water is
routed through the hand-spray.
NOTICE: When you dump the bowl of the toilet make sure all paper and solids have
cleared the slide mechanism before you allow it to close. Failure to do so can cause the
groove for the slide to become jammed and the slide will no longer close completely.
If the problem should occur a small nail or bent clothes hanger can be used to “pick”
the material out of the groove.
