The hold time for VacuFlush toilet systems is 2 to 3 hours. Afterwards it may cycle for 5 to 10 seconds then turn back off for another 2 to 3 hours. We recommend adding a kill switch to the system and turning it off when not in use.

VacuFlush systems that are cycling more frequently than 2 to 3 hours may be in need of service or repair. Often the culprit is a vacuum leak in the system. Items to inspect include hoses and clamps, toilet seals, the bellows and duckbill valves.
