Pick the 99H up before you judge it. At roughly 44 pounds, this blank carries about twice the polyethylene of most 22 gallon holding tanks in Ronco's line, which tells you where it came from: an application that wanted wall thickness, whether that is rough-road service, a long unsupported span, or a builder who simply specified heavy. If your original tank felt more like equipment than Tupperware, this is likely the family it belonged to.
Capacity and duty are standard for the class: 22 gallons of gray or black water, about 183 pounds when full at 8.34 pounds per gallon, and no potable rating because waste tanks never carry one. The 22 gallon family around it offers the same volume in lighter, dimensioned shapes, from the 10H box at 34 x 22 x 12 inches to the 30H, plus the 8H with end dump and mounting rails.
Like every molding out of Ronco's Tustin, California plant, in business since 1974, it ships with fittings installed to order: spin-weld or threaded, located wherever your plumbing needs them. The drawing below is printable at scale; mark your inlet, outlet, and vent on it, or place them with the on-page fitting planner, and that is what Ronco builds. Browse the full set at RV holding tanks. OneSource Plastics is an authorized Ronco Plastics dealer.
