A.A Fresh Water Tank Hose Connection Kit for RVs, Camper & Trailer — 3 Hoses, Fill Intake & Clamps

The A.A Fresh Water Tank Accessory Hose Connection Kit is a complete, ready-to-install plumbing set that supplies fill, pump and drainage hoses plus fittings and clamps for standard fresh water tanks.

Whether retrofitting an RV, concession trailer, camper or portable water system, this kit bundles the essential hoses, adapters and mounting parts so you can connect a fresh water tank quickly and reliably. All components are new and sized to match common tank ports—saving you multiple trips to the hardware store and reducing fitting compatibility guesswork.

How does this kit simplify installing a fresh water tank?

The kit includes appropriately sized hoses and matching connectors so you don’t have to source parts individually. Clear identification of each hose purpose—air/drainage, pump supply and fill—helps you route and secure connections correctly on the first try.

• 60-inch clear 1/2" I.D. hose for air venting and drainage
• 18-inch reinforced 1/2" I.D. hose to attach to your water pump
• 36-inch ribbed 1-1/4" I.D. hose for water filling
• Included fill intake with cover, drain spigot, 3 fittings and 7 hose clamps

What fittings and hardware are included, and how do they fit common tanks?

The kit supplies a water fill intake with a cover, a dedicated drainage spigot, barb-to-screw adapters and a set of hose clamps sized for the hoses provided. These parts are designed to work with standard 1.25" water fill ports and common 3/8" NPT connections, reducing compatibility issues during installation.

• Fill intake sized for 1.25" fill openings with protective cover
• Drain spigot suited for routine tank draining and maintenance
• Three small barb-to-screw fittings for secure pump and vent connections
• Two large clamps for fill hose, five small clamps for other hoses

How should I use each hose in the kit during setup?

Each hose has a specific function to keep your fresh water system performing correctly: the ribbed hose handles filling, the reinforced hose feeds your pump, and the clear hose vents or drains the tank. Following these roles helps maintain flow, avoids backpressure on the pump, and makes routine service or winterization easier.

• Ribbed 1-1/4" hose: route to external fill port to accept water supply
• Reinforced 1/2" hose: attach between tank outlet and water pump inlet
• Clear 1/2" hose: use for venting air and as a low-point drain line
• Secure all joints with supplied hose clamps to prevent leaks

What maintenance or compatibility should I be aware of?

The materials are suitable for typical potable water and RV systems, but periodic inspection of clamps and hoses will extend service life. Confirm your tank ports match the kit’s sizing—1.25" fill port and 3/8" NPT fittings—to ensure a straightforward fit.

• Inspect clamps for corrosion and retighten after initial use
• Check hoses for wear, kinks or soft spots annually
• Replace any fittings showing thread damage or persistent leaks
• Use the protective fill cover to keep contaminants out when not in use

Who is this for: This A.A kit is ideal for RV owners, camper renovators, concession trailer operators and DIY installers who need a compact, complete hose set to connect a standard fresh water tank. If you want to avoid mixing and matching parts, save time on installation, and equip a portable water system with properly matched hoses and clamps, this kit provides a practical, ready-to-install solution.
