Before you order
LILIE points out that in Europe dump stations use the 3" (76 mm) standard and that suitable adapters connect it to the US system. Before buying, check that your slide valve and hose are US standard. Before winter, drain the tank and leave the slide valve open or dried so it cannot freeze.
