Ronco Plastics RV37W - 14 Gallon Plastic RV Water Tank (29.75" x 16.0" x 7.5")

Seven and a half inches of height is the RV37W's defining spec. This 14-gallon fresh water tank spreads across 29.75 x 16 inches so that it can hide in floor channels and under-seat plenums where even a 9-inch tank would force the furniture up. Ronco's sheet flags it L.D. - light-duty - which is the potable designation: FDA-compliant natural polyethylene, translucent enough to see your water level through the wall.

Low tanks reward careful fitting placement. With the outlet at one end and the fill on top, a 7.5-inch water column drains cleanly without a sump; put the pickup at the low corner of your installation slope. Ronco installs every fitting to your marks at the plant, so print the drawing below, mark your fitting locations - or click them into place with the planner - and choose spin-weld or threaded.

Two siblings share the 14-gallon class in very different bodies: the RV3W at 29.75 x 13.88 x 8.12 inches is narrower for tighter runs, and the RV11W stacks 14 gallons vertically at 21 x 13 x 13 inches. The rest of the potable range is in the RV water tanks category.

Rotomolded in Tustin, California since 1974. It ships at 11 lb and carries about 117 lb of water when full. OneSource Plastics is an authorized Ronco Plastics dealer.
