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.
Order only the Vacuum Tester (Part Number 530002)
or as part of the complete system maintenance kit
(Part Number 310228).
SERVICE TIP
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.
