7.6 Locating potential vacuum leaks in base assembly
The VacuFlush toilet is part of a vacuum system that includes a vacuum pump and vacuum tank, or
a vacuum generator and discharge plumbing lines . If a vacuum leak is suspected, special equipment
will isolate the source of the leak . If the toilet is determined to be the source of the leak, there are
three possible areas to investigate:
1 . Flush ball and flush ball seal . See Problem 12 in Troubleshooting Guide .
2 . O-rings on the rotor shaft .
3 . O-rings around bottom of toilet base assembly .
Sources 1 and 2 will require the base assembly to be removed from the toilet and partially
disassembled .

At the end of each season, the VacuFlush toilet system should be winterized for storage . The
following procedure should be used:
1 . Pump out holding tank .
2 . Thoroughly flush system with fresh water .
3 . Drain freshwater tank .
4 . Add freshwater antifreeze to freshwater tank .
5 . Flush freshwater water antifreeze and water mixture through toilet and into the waste holding
tank . Each installation is different, so amounts may vary . User discretion is required to assure
adequate protection .
