Aussio RV Sink Drain Kit — Flexible 25" Hose, ABS Evacuation Flange with Cap, Chemical-Resistant Trap

Aussio's Flexible RV Sink Drain Kit is a complete, chemical-resistant single-sink drainage system that includes a 25" flexible hose, ABS evacuation flange with cap, and a durable trap for reliable gray-water removal in campers and outdoor kitchens.

This kit was created for compact living spaces where plumbing access is tight and durability matters. It combines a universal 1 1/2" threaded evacuation flange, a resilient polymer trap, and 25 inches of 3/4" ID flexible hose so you can route wastewater away from the galley quickly and with fewer fittings. Components resist common detergents and gray water, making the assembly suitable for repair projects, retrofits, or new RV builds.

How does this kit fit my RV sink and plumbing layout?

The Aussio drain kit is made to match standard RV sink threads and common under-sink layouts. The white evacuation flange accepts 1 1/2"–11 1/2 threaded sink drains so it works with most galley basins and compact sinks without custom adapters.

• Evacuation flange sized for standard 1 1/2" threads.
• 25" flexible hose allows routing around tanks and cabinetry.
• Fits single-sink systems in campers, pop-ups, and outdoor kitchens.
• Smooth interior hose reduces points for clogging or backflow.

What materials are used and will they resist common chemicals?

Key parts are built from an ABS flange and a chemically resistant polymer trap, chosen to tolerate detergents and typical gray-water exposure. The hose is manufactured for longevity and repeated use without cracking or degrading in RV environments.

• ABS evacuation flange and cap for strength and impact resistance.
• Chemical-defiant polymer trap for detergent and gray-water exposure.
• Flexible hose formulated to resist kinks and chemical wear.
• Seals and connections engineered for leak-free performance.

How easy is installation and what tools will I need?

Installation is designed for DIYers and RV technicians alike; basic hand tools are all that's required. The kit aligns with standard sink fittings and uses straightforward connections so you can upgrade an old drain or fit a new sink quickly.

• Compatible with standard 1 1/2" threaded sink drains—no special adapters needed.
• 25" hose simplifies routing so fewer elbows and clamps are required.
• Typical tools: adjustable wrench, plumber's putty or sealant, screwdriver.
• Clear layout reduces installation time and potential leak points.

What maintenance should I expect and how can I avoid clogs?

Routine maintenance is minimal: inspect connections periodically, rinse the drain after heavy use, and clear debris before it reaches the trap. The kit's smooth hose interior and accessible flange cap make it simpler to flush or clean when necessary.

• Periodic check of clamps and threaded connections for tightness.
• Flush with water after greasy or particulate-heavy use.
• Remove the evacuation cap to inspect or clear the trap if needed.
• Replace the flexible hose or seals at first sign of wear to prevent leaks.

Who is this for: The Aussio Flexible RV Sink Drain Kit is intended for RV owners, vanlifers, and DIY camper builders who need a dependable, compact drain solution. It's a practical choice when replacing worn hardware, finishing a custom galley, or outfitting a pop-up trailer that doesn't use a holding tank. Anyone wanting a straightforward installation with parts designed to resist detergents and everyday gray-water will find this kit suitable.
