Maintenance
If the bowl-sealing blade does not operate freely after
extended use, it may be restored to its original, smooth
operating condition by applying a light film of silicone
spray to the blade� To clean the toilet use Thetford
Aqua Bowl or any other high grade, non-abrasive
cleaner� Do not use highly concentrated or high acid
content household cleaners� They may damage the
rubber seals�
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�
