Maintenance intervals and normal parts replacement vary widely depending on numerous factors such as:
type of vessel, frequency of system use, quality of flushing water, etc. The chart below is intended strictly as a
general guideline. Owner discretion and consideration of actual usage must be the first basis for determining
proper maintenance levels.

Vacuum TeSTer
Dometic has developed a simple tool to assist in identifying
the location of vacuum leaks. The vacuum tester consists of a
vacuum gauge and a cone-shaped plug. Inserting the plug in the
inlet of the vacuum tank or generator isolates the toilet from the
system. In this way a troublesome leak can easily be located
in either system.

Checking for leaks behind or under toilets or other appliances can make it difficult to locate the source. Dripping
water at room temperature makes it difficult to feel wetness. Taking four or five sheets of toilet tissue and wiping
all seams and waterline connections offers a simple means of locating the general area of the leakage. Start at
the top of the unit since gravity will cause a leak to run downward. When the tissue comes in contact with the
leaking water, it will immediately change texture.
