At 34 lb bare, the B457 is a 30 gallon tank you can carry aboard under one arm - the light-shell counterpart to Ronco's armored 30 gallon molding. It suits protected installations: a dry locker, a ventilated bay, anywhere the tank is cradled and strapped rather than fending for itself against structure.
The B-series rule applies in full: this is a dual-role shell that becomes a fresh water tank or a gray/black waste holding tank purely by the fittings you order. Ronco spin-welds or thread-installs them at your marked positions before shipping, so print the drawing below, mark inlet, outlet, and vent where your plumbing runs, and let the on-page fitting planner translate hose sizes into fittings.
Light shell, heavy contents: full, the 30 gallons is about 250 lb of water, and the cradle carries all of it. Molded in Tustin, California, where Ronco has rotomolded since 1974. The thick-walled 30 and the rest of the mid-size range are in the boat tank category; RV formats live under RV water tanks. OneSource Plastics is an authorized Ronco Plastics dealer.
