any help would be appreciated.


If it's creating plenty of vacuum, it's most likely a failed vacuum switch.

If it's not building vacuum, it could be a bit of waste or TP is caught
in a duckbill...flushing a couple of bowlfuls of water through it should
solve the problem. If that doesn't solve it, and if it's been more
than a year since the duckbill valves in the pump have been replaced,
replacing 'em should solve it...that is, unless the bowl isn't holding
water. If it's not, try cleaning the cleaning the seal on the underside
of the hole. If the bowl still won't hold water, it's because the dome
is no longer seating...the spring is worn out. The fix is a 'ball, shaft
and cartridge kit"

The Vacuflush owners manual includes just about every possible symptom,
cause and cure that the system can develop. You can download and print
one from he
http://www.sealandtechnology.com/pdf...Flush%20OM.pdf
It doesn't matter that the manual is for the current model and yours is
several years old...the model refers only to the bowl size and discharge
location and the rest of the Vacuflush system hasn't changed enough to
notice since it was first introduced in the '70s. So the current manual
is just as useable for 20 yr old Vacuflush as it is for a brand new one.
