SEAFLO Large Joker Valve for Marine Toilets

The SEAFLO Large Joker Valve is a waste-line check valve designed for use in marine toilet discharge systems, providing reliable one-way flow to help prevent sewage backflow and odors. It is intended as a direct replacement for worn or failed valves in many marine and RV head systems, and installs with standard marine waste hose and clamps in existing plumbing runs. The valve helps maintain proper sealing under fluctuating waste-line pressures and supports typical marine sanitation hose sizes.

Key Features

  • One-way check design prevents backflow and odors, ensuring proper sanitation in marine toilet systems.
  • Heavy-duty construction improves durability over standard flexible valves, extending service life under frequent use and saltwater exposure.
  • Compatible with common marine waste-line hose sizes, allowing drop-in replacement without re-plumbing.
  • Simple installation requires standard hose clamps and existing waste-hose runs—no special tools needed.
  • Compact valve form saves space behind head compartments while maintaining effective waste-line control.
