At 46 lb for 48 gallons of capacity, the Ronco Plastics B293 is a manageable one-person install that still holds a serious week of fresh water. That ratio - light shell, big volume - is what makes this mid-size marine molding a favorite for sailboat refits where every tank has to come down a companionway ladder. Once filled it carries about 400 lb of water, so the shelf underneath does the real work.
Ronco builds the B293 to order rather than to a template: the tank arrives with spin-weld or threaded fittings installed at your marked positions, and nowhere else. Before you order, print the drawing below and lay your plumbing over it - where the pressure pump pickup wants to sit, where the deck fill drops in, where the vent can run high. The on-page fitting planner turns those pencil marks into a clean fitting spec. The polyethylene is FDA-grade, so the supply stays drinking-water safe for the life of the tank.
Ronco Plastics has molded marine water tanks in Tustin, California since 1974, and the B293 is squarely in the middle of that long-running line. Our boat tanks page holds the neighboring capacities, and the full Ronco Plastics catalog is the place to wander when the project scope inevitably grows. OneSource Plastics is an authorized Ronco Plastics dealer.
