MAKS 50-Gallon Fresh Water Tank with Dual Cone Design - 31x57x7 Low Point Drain
The MAKS 50-gallon fresh water tank delivers reliable potable water storage with a specialized dual-cone design for enhanced drainage performance. Measuring 31 inches by 57 inches by 7 inches, this molded tank features an end center low point drain configuration designed for complete water evacuation during winterization and maintenance. The dual cone design with factory-molded drain fitting ensures every drop can be drained from the system—critical for RVers in cold climates who need thorough winterization. Built with MAKS Plastics' proven seamless roto-molding technology and food-grade, UV-stabilized materials, this tank provides safe, clean fresh water storage for motorhomes, travel trailers, and fifth wheels.
Why Choose the MAKS 110009M Dual Cone Fresh Water Tank?
Running out of fresh water during an extended boondocking trip or dealing with a cracked, leaking tank can ruin your RV adventure. The MAKS 110009M solves these problems with generous 50-gallon capacity and bulletproof construction that lasts decades, not years. The dual cone interior design is engineered specifically for complete drainage—no stagnant water, no residue buildup, and no freeze damage during winter storage. Unlike cheaper alternatives that crack, leak, or develop algae problems, MAKS tanks are precision-molded from food-grade polyethylene with UV stabilizers built into the material itself, ensuring your fresh water stays clean and your tank stays intact through years of temperature extremes and road vibration.
Dual Cone Design for Complete Drainage
The dual cone interior design is what sets this tank apart from standard flat-bottom tanks. Two tapered interior sections funnel water toward the low point drain, allowing complete evacuation of every drop during winterization, maintenance, or system flushing. This design prevents stagnant water from sitting in the tank, reduces residue buildup, and eliminates the risk of freeze damage from trapped water. For RVers who store their rigs in cold climates or need thorough system flushing, the dual cone design is essential for proper maintenance and long-term tank health.

Top 5 Features That Make MAKS Plastics Tanks the Best on the Market
1. Seamless, Heavy-Duty Roto-Molding
MAKS tanks are manufactured using advanced rotational molding technology that creates a single-piece, seamless tank with uniform wall thickness. This eliminates weak points, seams, and potential leak areas that plague welded or multi-piece tanks.
2. Premium UV-Stabilized Materials Made for Real RV Conditions
Every MAKS tank is molded from high-grade polyethylene with UV inhibitors built into the material itself. This protects against sun exposure, temperature extremes, and degradation, ensuring your tank won't crack, fade, or fail prematurely.
3. Precision-Engineered Fit for RV Chassis
MAKS doesn't make generic tanks. Each model is designed to fit specific RV chassis configurations with exact dimensions, drain placements, and mounting provisions. This means easier installation, better space utilization, and proper integration with your RV's existing systems.
4. Made in the USA With Full In-House Engineering
MAKS Plastics manufactures every tank in the United States with complete control over materials, processes, and quality standards. Their in-house engineering team designs tanks specifically for the demands of RV use, not generic applications.
5. Proven Long-Term Reliability & Lower Lifetime Cost
MAKS tanks are built to last decades, not years. The combination of superior materials, seamless construction, and precision engineering means fewer replacements, less maintenance, and lower total cost of ownership compared to budget alternatives.
RV Applications & Compatibility
- Motorhomes requiring substantial fresh water capacity for extended travel
- Travel trailers for boondocking and dry camping without hookups
- Fifth wheels needing dual cone design for improved drainage and winterization

Installation & Winterization
Installing the MAKS 110009M is straightforward for RVers with basic mechanical skills. Verify the 31x57x7 dimensions fit your available space, secure the tank with proper mounting straps or brackets, connect plumbing fittings to the low point drain and fill locations, and ensure adequate venting. The dual cone design makes winterization simple—just open the low point drain valve and gravity does the rest, evacuating every drop of water to prevent freeze damage. Many RV owners successfully install these tanks themselves, though professional installation is recommended if you're unfamiliar with RV plumbing systems.
