Key Features & Benefits:
  • High-Capacity Drainage: The powerful 1100 GPH (4164 LPH) pump ensures rapid and efficient removal of shower and sink water, even during heavy use.
  • Automatic Operation: Activated by a non-mercury Rule-A-Matic float switch, the system turns on as water fills the tank and shuts off when empty, providing hands-free convenience.

  • Backflow Prevention: An integrated internal check valve minimizes water siphoning back into the shower box, helping to maintain hygiene and prevent odors.
  • 24V Power Efficiency: Optimized for larger vessels and RVs with 24V electrical systems, ensuring robust performance.
  • Robust Construction: Built with durable marine-grade materials and a tough, impact-resistant polycarbonate snap lid cover to withstand harsh marine environments.
