34 Gallon RV Black & Grey Water Holding Tank - Premium Seamless Construction
The Elkhart Plastics 34 Gallon RV Holding Tank (H1282/EPI 3010) delivers reliable, leak-proof waste storage for your recreational vehicle. Engineered with seamless roto-molded black polyethylene construction and consistent 0.180" wall thickness, this tank eliminates weak spots and ensures long-lasting durability in demanding RV applications.
Measuring 70-1/4" x 21-1/2" x 8", this blank holding tank provides flexible installation options for both black water and grey water systems. The 3-inch outlet diameter accommodates standard RV plumbing fittings, while the seamless design prevents leaks and odor escape.
Why Choose This 34 Gallon RV Holding Tank?
Seamless Roto-Molded Construction: Unlike welded or seamed tanks, our roto-molding process creates a one-piece tank with uniform wall thickness throughout. This eliminates weak points where cracks and leaks typically develop, ensuring your holding tank performs reliably for years.
Professional-Grade Black Polyethylene: The 0.180" thick black polyethylene material resists UV damage, chemical corrosion, and temperature extremes. Black coloring prevents algae growth and maintains a clean appearance even after extended use.
Flexible Blank Tank Design: This blank tank ships without pre-installed fittings, giving you complete control over drain placement, vent positioning, and sensor installation. Custom fitting placement ensures optimal performance in your specific RV layout.
Optimal 34 Gallon Capacity: The 34-gallon capacity strikes the perfect balance between extended holding time and manageable weight. Ideal for weekend trips and extended camping without frequent dump station visits.
Authentic Elkhart Plastics Quality: Manufactured by Elkhart Plastics/Ameri-Kart, a trusted name in RV component manufacturing. This tank meets rigorous quality and health safety standards required for potable water contact and waste containment.
