The 29-gallon capacity strikes the perfect balance between storage volume and space efficiency, making it ideal for weekend camping trips, extended boondocking adventures, and full-time RV living.

Why Choose the Elkhart Plastics EPI 2873 Holding Tank?
Authentic OEM Quality: Elkhart Plastics has been the go-to supplier for major RV manufacturers for decades. When you choose the EPI 2873, you're getting the exact same quality tank that comes factory-installed in new RVs—not a cheap aftermarket substitute. This is genuine OEM equipment built to the highest industry standards.
Heavy-Duty 0.180" Wall Thickness: Unlike thin-walled aftermarket tanks that crack and fail prematurely, the EPI 2873 features robust 0.180-inch polyethylene walls that resist impact damage, temperature extremes, and the constant stress of road vibration. This extra-thick construction ensures years of leak-free service even in the harshest conditions.
Seamless Roto-Molded Construction: Elkhart Plastics uses advanced rotational molding technology to create one-piece tanks with no seams, welds, or weak points. This manufacturing process produces uniform wall thickness throughout the entire tank, eliminating the stress concentrations and failure points common in cheaper welded tanks.
Low-Profile Design for Easy Installation: At just 7 inches tall, this tank fits perfectly in shallow under-floor compartments where vertical clearance is limited. The 60x28-inch footprint maximizes storage capacity while maintaining a compact profile that works in tight spaces. This makes replacement installations straightforward and hassle-free.
Chemical and Odor Resistant: The high-density black polyethylene construction resists degradation from RV holding tank chemicals, cleaners, and waste products. The material won't absorb odors or stains, and it maintains structural integrity even with continuous exposure to harsh tank treatments and sanitizers.
Temperature Stable: Whether you're camping in freezing winter conditions or scorching summer heat, this tank maintains its structural integrity. The polyethylene material resists cracking from freeze-thaw cycles and won't warp or deform in high temperatures, ensuring reliable performance year-round.

Installation and Compatibility
Installing the Elkhart Plastics EPI 2873 is straightforward for anyone with basic RV maintenance skills. Before installation, carefully measure your available mounting space to ensure proper fit—remember to account for drain fittings, vent connections, and mounting hardware. The tank should be securely mounted using appropriate straps or brackets to prevent movement during travel, and all connections should be sealed with proper RV-grade fittings and sealants.
This tank is compatible with standard RV waste systems including 3-inch termination fittings, vent pipes, and drain valves. For optimal performance and leak-free connections, we recommend using quality Elkhart Plastics tank fittings and accessories designed specifically for holding tank applications. Always follow proper RV sanitation practices and use appropriate holding tank treatments to maintain system performance.
Frequently Asked Questions
What's the difference between gray water and black water tanks? Gray water tanks collect drainage from sinks and showers, while black water tanks hold toilet waste. This tank can be used for either application depending on your RV's plumbing configuration and your specific needs.
Will this tank fit my RV? The EPI 2873 is designed for installations where you have at least 60" length, 28" width, and 7" height clearance, plus additional room for fittings and connections. Measure your available space carefully and compare against these dimensions to ensure proper fit.
How do I know if this is the right replacement for my damaged tank? Check your existing tank for part numbers—if you see EPI 2873 or H1128 stamped on the tank, this is an exact replacement. If you have different part numbers, measure your tank dimensions and compare them to this product's specifications.
What makes Elkhart Plastics tanks better than aftermarket alternatives? Elkhart Plastics manufactures OEM tanks for major RV brands. You're getting factory-quality equipment with heavy-duty 0.180" walls, seamless construction, and proven durability—not a thin-walled aftermarket imitation that will crack and fail prematurely.
Can this tank handle freezing temperatures? While the polyethylene material resists cracking from freeze-thaw cycles better than many materials, you should still winterize your RV holding tanks and avoid storing liquid waste in freezing conditions to prevent damage to valves, fittings, and sensors.
