Winterizing

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.

6.Empty holding tank.

NOTE: Use nontoxic antifreeze designated for potable water systems. (See vehicle owner’s manual.)

Never use automotive-type antifreeze in freshwater systems.

Maintaining The System

Maintenance intervals and normal parts replacement vary widely depending on factors such as frequency of system use, quality of flushing water, etc. The chart below is intended as a general guide in keeping your sanitation system 100% ready for use at any time.
