Gray water is the tank people forget to plan, and the B445 is a strong candidate for the job: 35 gallons in a thick 102 lb shell that shrugs off the warm, soapy, grease-laced discharge that galley sinks and showers produce. But call it a gray water tank and you have only named one of its lives - as a dual-role B-series molding it is equally a fresh water tank or a black water holding tank, decided by the fittings.
Ronco installs those fittings per order: spin-welded or thread-mounted, at exactly the positions you mark. Print the drawing below, trace your drain runs to it, mark inlet, pump-out or supply, and vent, and run the choices through the on-page fitting planner before submitting.
Full, the 35 gallons weighs about 292 lb. The tank is rotomolded in Tustin, California, where Ronco has built nothing but plastic tanks since 1974. Waste-specific shapes are gathered in the holding tank category, marine formats in the boat tank category, and the entire family on the Ronco Plastics hub. OneSource Plastics is an authorized Ronco Plastics dealer.
