The lawn crew weed wacked our sewer hose with the weed wacker. We didn’t know. Later Tim went to dump the tanks… And the hose was shredded. Guess who was wearing brand-new sneakers. Always check your hose before opening the valve.
When we bought our Seneca, nobody told us there was a second gray tank. So we did 17 loads of laundry. Then the basement flooded. Lesson: learn every tank in your RV. Anyone else ever discover a “surprise system”?
