The Ronco Plastics B496 is the light-and-simple take on 25 gallons: a 33 lb rotomolded polyethylene shell that one person lifts, positions, and installs without drama. For cradled, well-supported compartments, this is all the tank the job requires.
As a dual-role B-series molding it keeps both careers open. A fresh water order produces a potable tank, the polyethylene food-contact grade; a waste order produces a gray or black holding tank in the identical shell. Fittings are never molded in; Ronco installs them per order, spin-welded or threaded at the exact spots you mark, so your plumbing dictates the tank rather than the reverse.
Full, the B496 carries about 208 lb of water at 8.34 lb per gallon, far beyond its own weight, so the fastening deserves more thought than the lifting. Print the dimensioned drawing below and finalize port placement through the on-page fitting planner.
Molded in Tustin, California by Ronco Plastics, established 1974. Its heavy-wall sibling in the same capacity shows the other philosophy, while the 25 gallon water tank and 25 gallon holding tank cover the single-role paths; the marine line holds the rest. OneSource Plastics is an authorized Ronco Plastics dealer.
