The Ronco Plastics B397 is a 33 gallon B-series marine molding shipping at 90 lb, which places it firmly in Ronco's heavy-wall camp. Thirty-three gallons covers a serious weekend for two aboard, or a full gray water cycle for a compact liveaboard, and the dual-role shell covers either job: potable fittings for a food-grade fresh water tank, waste fittings for a gray or black holding tank.
Full, it carries about 275 lb of water at 8.34 lb per gallon. The thick wall keeps the shape honest under that load even where support is imperfect.
No fitting is pre-placed. Print the drawing below, mark inlet, outlet, and vent where your plumbing runs, and the factory installs each one per order, spin-welded or threaded to spec; the fitting planner on this page collects the details. Ronco has built tanks to individual order in Tustin, California since 1974.
