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 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: The pedal must be held completely
down to flush. A good flush should be obtained
within 2 to 3 seconds� If problem persists, remove
the water supply line and check flow rate.
