The Ronco Plastics B169 holds 28 gallons and ships at 36 lb, which places it in the sweet spot of the marine fresh water range: enough capacity for real cruising days, light enough to maneuver into a locker without a second pair of hands. It is a one-piece FDA-compliant polyethylene molding for potable service - the material that ended the era of rusting steel and weeping fiberglass water tanks, molded by Ronco in Tustin, California since 1974.
What separates it from a commodity tank is the finish-to-order step.
Filled, the B169 carries about 234 lb - water at 8.34 lb per gallon is the heaviest thing most people never weigh - so build the base flat, strap it tight, and mount it low. Alternative 28 gallon footprints and every other size are under boat tanks, with the full line at the Ronco Plastics hub and shipping quotes at the freight estimator. One Source Plastics is an authorized Ronco Plastics dealer.
Fittings
This tank has a molded shape (see the drawing), so it is sold as a blank tank with no fittings installed. Add the Ronco 3-inch uniseal (F3UNISEAL), a loose pipe-to-tank seal you install yourself, if you need a sealed pipe connection.
