Seventeen gallons at 20 lb - pound for pound, the B226 is one of the lightest ways into a real marine fresh water system. Tanks in this class often end up in boats making the jump from portable jugs to plumbed water: a small cruiser getting its first galley sink, a fishing boat adding a washdown, a restoration finally replacing whatever the previous owner rigged. Light enough to position solo, sized to matter.
The molding is rotomolded FDA-compliant polyethylene, rated for potable water, with the seamless one-piece wall that is the whole reason plastic displaced fabricated tanks in small craft. And it ships bare of fittings by design: print the drawing below, mark your fill, vent, and pickup around the hardware already living in the compartment, and Ronco spin-welds or thread-installs each fitting to your marks. The on-page fitting planner captures the layout by click if that is easier than a pencil.
Full, the tank carries about 142 lb of water at 8.34 lb per gallon. Bear it flat, strap to structure, and it will do what tanks from the Tustin, California shop have done since 1974 - disappear into the boat and stay out of the conversation.
Neighboring small sizes are in the boat tank category; the whole molding list is on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
