Frequently Asked Questions

Q: How do I know if I need the low-profile or high-profile pedal?
Match the pedal to your toilet base height.

• Low Profile = Shorter toilet height
• High Profile = Taller, chair-height toilet

If unsure, the model label under the toilet lid or behind the shroud will identify it.

Q: Will this pedal fit Style Lite or Style Plus toilets?
No. This part is only for Style II and Residence toilets.

Q: Is this an OEM part from Thetford?
Yes. The 42078 is the genuine factory replacement.

Q: My pedal presses down but no flush occurs. Will replacing the pedal fix it?
If the pedal linkage is broken or the pedal no longer engages the mechanism, yes.
However, if the water valve or waste ball is faulty, additional repairs may be needed.

Q: Can I install this myself?
Yes. Most RV owners can complete installation with standard tools.
