That doesn't sound like you're using enough flush water Larry...and it's too little flush water that's responsible for 99% of problems with VacuFlush. You should be leaving the peddle down at least 3-4 seconds after urine only, a full 10 seconds after solids and/or TP. Any less doesn't put enough water through it to rinse bits of paper and solids out of the pump and duckbills. If you insist on keeping on with the way you're doing it, at least flush a full bowl of clean water through it once a day. That's a small change, but will prevent problems...and prevention is always easier and cheaper than cure!
