Ronco Plastics 17H - 25 Gallon Plastic RV Holding Tank

Here is the ordering ritual that makes a Ronco tank different from a parts-store tank, using the 17H as the example. You print the technical drawing from the block below this description. You take it under the coach and mark, in pen, where the inlet enters, where the outlet drops, where the vent rises, matching the plumbing that already exists. That marked sheet, or the same picks made in the click-to-place fitting planner, goes in with your order, and Ronco spin-welds or threads the fittings at those points before the tank ships. No hole saw, no bulkhead-fitting roulette, no guessing.

The tank receiving this treatment is a 25 gallon gray or black water holding molding, about 26 pounds empty and roughly 208 pounds full at 8.34 pounds per gallon, with no potable rating. It comes out of Tustin, California, where Ronco Plastics has rotomolded RV tanks since 1974.

Confirm the shape against your cavity before you fall in love: the dimensioned 25 gallon options are the 11H at 37 x 20.25 x 11.5 inches and the 45H at 74 x 15 x 8.25, and one step up sits the 54H at 28 x 22 x 11.5. The full catalog is at RV holding tanks. OneSource Plastics is an authorized Ronco Plastics dealer.
