The Jayco Seneca’s sewer and water system is designed for both convenience and efficiency, making campsite setup and maintenance a breeze. With clearly labelled connections and easy-access panels, managing fresh water, grey water, and black water is straightforward—even for first-time RVers. The onboard system includes a sizeable fresh water tank, along with reliable holding tanks that make extended stays more comfortable. A built-in black tank flush and user-friendly controls take the guesswork out of keeping things clean and functional. Whether you’re hooked up at a full-service site or boondocking off-grid, the Seneca’s plumbing system helps ensure everything flows smoothly—literally.
