Upgrade your RV's waste management system with the Alpha VB32547HBLANK, a premium 39-gallon holding tank engineered to meet or exceed OEM standards. This rotational molded tank features extra-durable one-piece construction, center drain configuration, rigorous leak testing, and superior durability that outlasts factory-installed tanks. With low-profile dimensions of 54" x 32" x 7", this tank maximizes capacity while fitting in tight vertical spaces.
Why Choose the Alpha VB32547HBLANK Holding Tank?
Extra-Durable Rotational Molded Construction
Engineered with heavy-duty rotational molding, the VB32547HBLANK features seamless one-piece construction that eliminates weak points and potential failure areas. This superior manufacturing process creates a tank that's significantly stronger and more durable than typical factory-installed holding tanks.
Center Drain Configuration for Optimal Performance
The center drain design ensures efficient waste evacuation and complete tank drainage. This configuration minimizes residue buildup and makes cleaning easier, extending the life of your RV's waste management system.
Rigorous Leak Testing for Peace of Mind
Every Alpha VB32547HBLANK is individually submerged and pressure-tested for leaks before shipping. This comprehensive quality control ensures your tank is 100% leak-proof from day one, giving you confidence that your RV's waste management system will perform flawlessly.
NSF Certified for Safety and Quality
Built to meet or exceed NSF certification standards for RV waste management, the VB32547HBLANK is designed to safely contain black water and gray water waste. The durable construction resists odors, stains, and degradation even after years of use.
Low-Profile Design for Tight Spaces
With just 7 inches of height, this 39-gallon tank is perfect for installations where vertical clearance is limited. The 54" x 32" footprint provides generous capacity while fitting into spaces where taller tanks simply won't work.
Built for the RV Lifestyle
Designed to withstand the constant movement, vibration, and temperature changes that come with RV travel, this tank maintains its integrity mile after mile. The robust construction ensures reliable performance whether you're boondocking in the desert or camping in freezing temperatures.
