Product Description
31 Gallon Marine & RV Tank | Holding & Fresh Water | Trionic WH-2031-1
The 31 Gallon Trionic Marine & RV Tank | WH-2031-1 is designed for compact installations in boats, RVs, campers, and other mobile applications where a durable, space-efficient tank is required. This rectangular polyethylene tank supports fresh and potable water storage as well as wastewater holding, including grey and black water, in non-pressurized setups.
With a footprint of 33" L × 20" W × 11.5" H, the WH-2031-1 balances practical capacity with flexible placement. It is manufactured as a seamless, one-piece rotationally molded tank with an approximate 3/8" average wall thickness.
Pre-drilled vs blank: The WH-2031-1 is the pre-drilled, fittings configuration and uses Trionic’s standard threaded opening pattern: 2 openings at 1-1/2" FPT and 2 openings at 1/2" FPT, with female NPT threads, located on one end. Unused openings can be capped. If your application requires custom fitting placement, Trionic also offers the blank tank option B-2031-1 with no openings, commonly used with a CF-60 custom fittings kit.
Installation note: Install with the bottom fully supported and use a minimum 12" flexible hose section to hose barb fittings.
