Winterizing Pump

Plan your winterizing and storage ahead, and be sure
the holding tanks are drained and flushed thoroughly.
This is very important, as the frozen sewage and water
could seriously damage the system� After dumping
tanks, add a quart or two of RV, non-toxic antifreeze to
one of the holding tanks and start the macerator pump�
Run the pump until the RV, non-toxic antifreeze comes
out the end of the pump hose� Leave dump valves
open� As extra protection, open the toilet valve and add
a quart of RV, non-toxic antifreeze to the Black Water
tank and pour a quart of RV, non-toxic antifreeze into
a sink drain to protect the holding tanks, valves, and
pump from residual water freezing. Pump to fill the
hose completely�
NOTE
In very cold weather, winterizing the touring coach
is recommending to prevent damage to the waste
systems. Use common sense and winterize as
needed.

Toilet

The RV toilet in your Airstream is a design that has
been used for many years. To flush, press down on the
foot pedal, this dumps the sewage and flushes fresh
water down the side of the bowl� Water will continue
to run into the bowl for a short time after the pedal is
released� Follow the manufacturer's instruction on
operating, cleaning, and sanitizing toilet�
NOTE
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.
Troubleshooting
1� Leaks:
a� Back of toilet: check water supply line connec-
tion at water valve� Secure or tighten as neces-
sary� If leak persists from water valve, replace�
b� Vacuum breaker leaks while flushing: replace
vacuum breaker or water module, depending
on model�
c� Between closet flange and toilet: check flange
nuts for tightness� If leak continues, remove
toilet and check flange height. Use Thetford
spacers to adjust, if necessary, to 7/16-in�
above floor. Replace flange seal.
2� Toilet won't hold water:
a� Check for and remove any debris from blade-
ball seal track�
b� Check blade/ball seal compression mecha-
nism� If blade/ball seal is worn, replace�
3� Harder than normal pedal or hand lever operation:
Apply light film of Thetford Toilet Seal Lubricant &
Conditioner or silicone spray to blade/ball� (Note:
To avoid damage, do not use spray lubricants other
than silicone�)
4� Poor flush: Pedals or hand levers must be held
fully open during flush. A good flush should be
obtained within 2 to 3 seconds� If problem persists,
remove the water supply line and check flow rate.
The flow rate should be at least 10 qt (9.5 L) per
minute�
