Kohree RV Sewer Hose Support 15FT — Black 3-inch U-Channel, Steeper Slope for Faster Drainage

Kohree RV Sewer Hose Support 15FT is a ready-to-use, adjustable black holder that stabilizes up to 15 feet of 3-inch RV sewer hose to prevent sagging and speed drainage.

Whether you're parked at a campground or boondocking, a reliable sewer hose support keeps waste flowing where it should and helps avoid messy backups. The Kohree support arrives preassembled, unfolds quickly, and uses a deep U-shaped profile plus a steeper slope to promote smooth, consistent drainage. Constructed from durable polypropylene with reinforced hinges, it resists cracking and stands up to repeated use while folding compactly for transport.

How does this support improve dumping speed and reduce sagging?

The Kohree design raises and aligns the hose to maintain a steady fall from your RV to the dump point, eliminating low spots where solids and liquids can collect. The steeper slope and U-shaped cradle keep the hose seated during flow so the line remains clear and efficient.

• Deep U-shaped channel keeps hose centered and prevents side slippage.
• Steeper built-in slope encourages faster gravity-assisted drainage.
• Accordion-style sections compress and expand to create smooth runs without dips.

Is the Kohree support durable enough for regular RV use?

This unit is made from high-quality polypropylene chosen for toughness and weather resistance, so it won’t become brittle from sunlight or crack under normal campsite conditions. The hinges and interlocking sections are reinforced to tolerate repeated folding and unfolding without failure.

• Sturdy PP material resists aging and cracking compared to thinner plastics.
• Reinforced hinge points designed to withstand repeated use.
• Compact folding design protects parts when stored with the carrying strap.

How easy is it to set up, adjust, and store?

Kohree’s support is ready to use out of the box with no assembly required: pull it open, position under the hose, and adjust the layout. The accordion sections make it simple to change height or curve around obstacles, then collapse flat for storage and secure with the included strap.

• No tools or assembly — unfold and position in seconds.
• Adjustable length and flexible joints let you form curves or straight runs.
• Folds compactly and includes a strap for tidy transport and storage.

Will it work with my RV hose and dump station?

The Kohree support fits standard 3-inch RV sewer hoses and accommodates runs up to 15 feet long, making it compatible with most RV setups and campground dump locations. Its universal U-channel accepts common hose sizes and stays stable on a variety of ground surfaces.

• Compatible with 3-inch diameter sewer hoses used by most RVs.
• Designed for runs up to 15 feet without sagging.
• Stable on gravel, dirt, pavement, and grass thanks to the deep cradle.

Who is this for: The Kohree RV Sewer Hose Support is intended for RV owners who want a simple, reliable way to manage waste hose runs—campers who frequently use dump stations, families on extended trips, and anyone who prefers a cleaner, faster dumping process. It suits both occasional users who want fuss-free setup and experienced RVers who need a robust, weather-resistant support that stores compactly.
