A.A 10 Gallon RV Fresh/Gray Water Tank — BPA-Free Polyethylene, Compact Rotationally Molded with 1.25" Fill Inlet

The A.A 10 gallon RV fresh/gray water tank is a seamless, BPA-free polyethylene reservoir designed for non-pressurized potable and gray water storage in RVs, trailers and marine applications.

This compact, rotationally molded tank combines one-piece construction and corrosion-resistant materials to give a durable, lightweight water storage option where space and reliability matter. Built with a 1.25" water fill inlet and three 3/8" NPT fittings, it’s intended for systems that require venting and professional installation of plumbing components. Before using for food-service or potable water, sanitation and local health-department compliance checks are recommended.

How does the tank fit into tight RV or trailer spaces?

Its compact dimensions and shallow profile make this tank easy to position in confined compartments. The rectangular shape and 1/8" average wall thickness let you rotate the tank to change which side is the footprint or height, making orientation flexible for custom installations.

• Dimensions: approximately 10.5" x 14.5" x 17" (longest length without fittings).
• Average wall thickness ~1/8" for a balance of strength and low weight.
• Rotate the tank to use different faces as base or height.
• Lightweight polyethylene helps reduce payload compared with metal tanks.

What connections and plumbing preparations are required?

The tank arrives with a single 1.25" water fill inlet and three 3/8" NPT ports for outlets or sensors, but additional fittings and hoses are normally required to integrate it into a system. Because this is a non-pressurized tank, it must be vented to avoid deformation and piping damage when filling or draining.

• Includes: (1) 1.25" fill inlet and (3) 3/8" NPT connections.
• Buy compatible food-grade fill hoses and fittings separately for your layout.
• Install a vent to allow air exchange during use; do not connect a pressurized hose directly without venting.
• A certified technician is recommended for fitting installation to prevent overtightening or damage.

How should I install and secure this tank for safe transport?

Proper mounting and bracing prevent shifting and stress during travel. Place the tank on a flat surface and use straps or brackets that support its base and sides; never suspend the tank by straps alone or place heavy loads on top.

• Mount on a level surface and brace against movement—use straps or custom brackets supporting the base.
• Do not hang the tank only by straps; that may deform or damage the polyethylene.
• Avoid placing weight or objects on top of the tank to prevent compression or fitting stress.
• Remember that cutting or modifying the tank voids the warranty.

What maintenance and sanitation steps are recommended before use?

Because tanks can collect manufacturing debris or warehouse dust, wash and sanitize before introducing potable water or food-contact use. Routine cleaning reduces biofilm and odor risk, and you should always confirm local health-department standards if using the tank in food-service settings.

• Wipe external dust or scuffs with a damp cloth before installation.
• Sanitize the interior following standard potable water tank procedures prior to first use.
• Check and replace hoses and fittings periodically to maintain sanitary connections.
• Verify local health-inspection requirements for fresh- and gray-water tanks and fittings before purchasing.

Who is this for: The A.A 10 gallon tank is aimed at RV owners, concession or food vendors, horse trailer builders and small marine installations that need a compact, durable, non-pressurized water reservoir. Choose this tank if you want a seamless, corrosion-resistant polyethylene option that’s easy to position in limited spaces and compatible with standard NPT fittings—provided you plan for venting, appropriate fittings, and professional or experienced installation.
