SEACHOICE Large Self Bailing Scupper | Automatic Marine Deck Drainage

Ensure a dry, safe, and worry-free boating experience with the SEACHOICE Large Self Bailing Scupper. Expertly engineered for the demanding marine environment, this essential piece of boat plumbing equipment provides a reliable, automatic solution for clearing water from your vessel´s self-bailing decks. Say goodbye to standing water and the constant need for manual bailing, and hello to enhanced safety and peace of mind on every journey.

This scupper is designed to automatically seal and drain self bailing decks, acting as a critical barrier against water intrusion while allowing accumulated spray, rain, or wash-down water to escape quickly and efficiently. Its intelligent design prevents backflow, meaning water can get out, but it can´t get back in, even in choppy conditions.

Key Benefits:

* Automatic, Hands-Free Operation: The innovative internal mechanism works passively, opening to drain water as it collects and closing to prevent backwash, requiring no manual intervention from the operator.
* Rapid, High-Volume Drainage: The "Large" design facilitates a superior flow rate, ensuring that your deck is cleared of water swiftly, minimizing slip hazards and keeping your gear dry.
* Enhanced On-Deck Safety: By effectively eliminating standing water, this scupper significantly reduces the risk of slips and falls for you and your passengers, creating a safer environment for fishing, cruising, and all on-water activities.
* Superior Durability: Constructed from high-grade materials chosen for their resilience, this scupper is built to withstand the harsh realities of the marine world, including UV degradation, saltwater corrosion, and temperature fluctuations.
* Prevents Water Backflow: The reliable sealing mechanism ensures that following seas or reverse motion won´t force water back onto your deck through the drain, a common issue with inferior scupper designs.

Main Features:

The core of this scupper´s functionality lies in its simple yet effective design. It is made of a tough, impact-resistant polycarbonate material, providing a long service life without becoming brittle or cracking. Inside the housing, a solid polyethylene ball and a durable PVC seal work in tandem. Gravity and water pressure from the deck force the ball away from the seal, opening the passage for water to drain out. When the deck is dry or when outside water pressure is applied, the ball is pushed firmly against the PVC seal, creating a watertight barrier. This entire assembly is designed to be mounted on the transom above the water line for optimal performance and easy installation.

Valves System:

This unit functions as a highly effective one-way check valve. The internal solid polyethylene ball acts as the valve´s moving component, while the precision-molded PVC ring serves as the valve seat. This ball-check valve system is renowned for its reliability and low maintenance, providing a positive seal that you can depend on to keep your cockpit or deck dry.
