Parts Desk Insights

Best Use Case: Use this kit when you need to change where your holding tank hose or fitting connection exits the tank—such as rerouting plumbing during upgrades or repairs.

Common Issues: Dry-fit the routing first to confirm hose reach and alignment, then review the included instructions before final assembly. If you’re working on or near existing threaded openings, ensure surfaces are properly prepared and mating parts are seated correctly to avoid leaks.
