Ronco Plastics RV30W - 20 Gallon Plastic RV Water Tank

Ronco's price sheet lists this one as the 30 W, a light-duty 20 gallon fresh water molding, and it earns its keep as the odd shape in a crowded size class. Ronco Plastics runs four different 20 gallon RV water tanks at once because coach builders never agreed on a cavity: the RV39W at 35 x 13 x 11 inches, the RV57W at 32 x 16.5 x 10, and the low RV72W at 35 x 19 x 7.75 all hold the same water in very different footprints. Measure your compartment against the drawing before you commit.

As a W-series tank it is molded in FDA-compliant natural polyethylene, the translucent kind that lets you eyeball the water level through the wall, and it is rated for potable fresh water. The blank weighs about 11 pounds empty; filled, 20 gallons at 8.34 pounds per gallon puts roughly 167 pounds on your floor or frame, so plan the support before the plumbing.

Every tank leaves Tustin, California, where Ronco has rotomolded RV tanks since 1974, with fittings spin-welded or threaded exactly where you spec them. Print the drawing further down this page, mark inlet, outlet, and vent right on it, or use the click-to-place planner, and the tank arrives ready to plumb. The rest of the line lives under RV water tanks. OneSource Plastics is an authorized Ronco Plastics dealer.
