A conventional recreation vehicle or caravan toilet, which normally is connected by a simple slide valve to a holding tank mounted below it, can be easily converted to a vacuum toilet at a campground or like stationary site. The holding tank is slid out of the compartment in which it is mounted below the toilet of the recreation vehicle or caravan, and a vacuum adaptor is slid into its place, making a substantially airtight connection with the toilet. The vacuum adaptor is connected up to a substantially stationary vacuum source, such as a below ground vacuum tank at a campground. The vacuum adaptor is preferably connected by a dripless connection to the vacuum source, and includes an arcuately shaped movable valve element that is rotatable about a substantially horizontal axis from a substantially airtight closed position, to an open position, when the toilet is flushed.
