Stop fighting gravity and sagging dump hoses. The Valterra Slunky S1500 holds your 15 feet of sewer hose off the ground in a continuous downhill slope so waste flows cleanly from your RV to the dump station inlet every single time -- no puddles, no backflow, no embarrassing spills at the campsite.
Anyone who has wrestled with a sewer hose flopped across a gravel pad or propped up with sticks and rocks knows the problem. Without consistent elevation and slope, waste can pool inside the hose, leave residue, and create odor issues in your site. The Valterra Slunky solves that with a simple accordion-style ribbed support that fans out flat on any surface and cradles your hose in a gradual, gravity-fed slope.
The S1500 is the 15-foot version in the Slunky lineup -- the right choice when your RV sewer outlet sits more than about 8-10 feet from the dump station pedestal, or when you need extra reach on an angled site. It collapses into a compact coil (9.25 x 8.25 x 6.75 inches) that stores easily in your bumper, cargo bay, or sewer kit tote.
Accordion design fans out on any ground surface and holds your hose at a consistent downhill angle from RV to dump inlet.
Open ribbed cradle accepts all standard 3-inch RV sewer hoses including Valterra, Camco, Lippert, and most other brands.
Collapses to just 9.25 x 8.25 x 6.75 inches and weighs under 4 lbs -- fits in a standard RV bumper or cargo bay pouch.
Ribbed rigid plastic construction holds its shape on gravel, concrete, dirt, and grass without buckling under hose weight.
Valterra makes the Slunky in several lengths to match different campsite setups. The S1000 covers 10 feet, the S1500 covers 15 feet, and the S2000 covers 20 feet. All use the same accordion-style ribbed cradle design and collapse to a similar storage footprint. If your site regularly puts the dump pedestal more than 10 feet from your RV outlet, the S1500 is the sweet spot -- long enough for nearly any standard campsite hookup without the extra bulk of the 20-foot version.
Setup takes about 30 seconds. Fan the Slunky accordion sections out along the ground between your RV sewer outlet and the dump station inlet, adjust the angle of individual sections to compensate for uneven ground, and lay your sewer hose into the cradle. The ribs keep the hose centered and elevated even when the hose is full.
The S1500 is a support-only product -- it does not include a sewer hose, bayonet fittings, or inline cap. Valterra and Camco both make compatible 15-foot and 20-foot sewer hoses with standard 3-inch bayonet fittings that drop right into this support. For a complete dump station kit, pair the S1500 with:
