What does FDA compliant actually buy you in a water tank? For the RVB427, it means the polyethylene resin itself is approved for contact with drinking water - no leached taste, no questionable plasticizers, nothing between you and 105 gallons of clean supply. Plenty of generic tanks look identical from the outside; the resin certificate is the part you cannot see, and on a tank your family drinks from, it is the part that matters most.
Ronco has molded potable tanks in Tustin, California since 1974, and the RVB427 follows the house recipe: light-duty B-series construction, translucent natural finish, 115 pounds as molded. Translucent natural PE is the honest choice for potable service - you can see the water level through the wall, and you can see the water itself, which colored tanks hide.
The 105 gallon capacity puts this molding in serious-supply territory for large trailers and working rigs, and full weight scales accordingly at 8.34 pounds per gallon. Mount it low, over structure, with the bay floor supporting the full base. Fittings are installed at the plant per your order - spin-welded or threaded at your marked positions - so print the technical drawing below, lay out your ports, and verify with the fitting planner on this page.
The RV water tank family holds the smaller stock sizes, and the Ronco Plastics hub maps every footprint in the line. OneSource Plastics is an authorized Ronco Plastics dealer.
