Without the Snake Blocker Pro, there is about a 1″ gap around the sewer hose and access hatch. This gap provides easy entry into your coach and storage bins for snakes, rodents, and other pests. Also, basement heat is sucked out of this gap during winter RVing, often exposing water lines to freezing conditions.
- Keeps snakes, rodents and pests out of your RV and storage bins
