Description
This 5-gallon Ronco marine holding tank (B322) is purpose-built for blackwater and greywater waste storage on boats and watercraft. Measuring 21" x 8 1/4" x 8", it is designed to fit common marine compartment layouts while providing dependable waste containment for time spent on the water.
Constructed from rotationally molded polyethylene, this tank is resistant to corrosion, chemicals, and impact damage. The seamless one-piece construction prevents leaks and stands up to the harsh marine environment over years of use.
Manufactured with ANSI/NSF 61 certified resin, confirming that the materials meet independent safety and quality standards for tank construction.
Installation Note: This tank is designed for above-ground, non-pressurized use. Always consult a qualified marine technician for proper mounting, plumbing connections, pump-out fittings, and venting requirements specific to your vessel. One Clarion is not responsible for installation-related issues.
