Thirty gallons, 36 lb on the shipping scale: the Ronco Plastics B179 is the fresh water tank for crews who want cruising capacity without a two-person install. Thirty gallons runs a boat's galley and taps for days, and the one-piece FDA-compliant polyethylene molding carries it without seams, corrosion, or aftertaste. It comes from Tustin, California, where Ronco has been molding marine tanks since 1974 - long enough that many B179s will be replacing tanks Ronco also made.
The finish-to-order system is the same one that built that longevity: fittings installed per order, spin-welded or threaded exactly where you mark them. Print the dimensioned drawing below and treat it as the first page of the installation - fill under the deck plate, vent at the high point, pickup where your boat's trim leaves the last gallon - then formalize the plan in the fitting planner on this page.
Full, it carries about 250 lb of water. Frame the platform flat, strap it firmly, and mount it low; do that once and the tank becomes the most reliable system aboard. Other 30 gallon footprints and the full capacity ladder are at boat tanks, the complete catalog at the Ronco Plastics hub, and shipping quotes at the freight estimator. OneSource Plastics is an authorized Ronco Plastics dealer.
