Camco RV 3" Waste Valve with 72" Cable Extension Kit — Sidewall or Compartment Mount, Ergonomic Handle

Camco’s 3-inch RV waste valve with a 72" flexible cable extension relocates the dump handle to an easier spot, making black/gray tank discharge simpler and safer to access.

This extension kit is engineered to solve one of the most common camper frustrations: a hard-to-reach waste valve handle. The assembly includes a full 3" diameter valve, a 72" flexible cable or hand assembly, a durable valve housing and a mounting bracket so you can position the control where it’s convenient on your sidewall or inside an access compartment. Materials and fit are selected to match standard RV sanitation plumbing so the upgrade integrates with most trailers and motorhomes.

How does the cable extension make daily dumping easier?

By moving the handle to a reachable location, the flexible cable lets you operate the valve without climbing or awkward reaching. The long, pliable cable preserves mechanical control and returns consistent motion from the relocated handle to the valve shaft.

• 72" flexible cable gives ample reach for sidewall or compartment placement
• Ergonomic handle reduces bending and stretching
• Mechanical linkage avoids reliance on electric actuators or power
• Compatible with common 3" RV waste valve openings

Is installation complicated for a typical RV owner?

Installation is designed for straightforward retrofit into standard RV plumbing. The kit mounts either to the exterior sidewall or inside an access compartment and requires basic tools and a standard waste valve opening for replacement or upgrade.

• Fits existing 3" waste valve cutouts or replaces older valves directly
• Mounting bracket secures the handle where you choose to place it
• Simple mechanical connections; no wiring or batteries needed
• Clearances and routing allow flexible pathing of the cable assembly

What components are included and what materials should I expect?

The kit supplies everything needed for operation: the 3" waste valve, the flexible 72" cable or hand assembly, valve housing and a handle mounting bracket. Parts are built to withstand RV use and exposure to the elements when installed in an exterior location.

• 3" waste valve body sized for standard RV sanitation pipes
• 72" flexible cable or hand assembly engineered for repeated use
• Sturdy valve housing and mounting bracket for fixed placement
• Durable finishes that resist corrosion and wear on the road

How do I choose the best mounting spot on my coach?

Pick a location that balances convenience, protection and cable routing. Many owners mount to the sidewall near existing service panels or inside a lower control access compartment to keep the handle weather-protected while remaining reachable.

• Sidewall mounting gives fast exterior access while parked
• Control compartment mounting hides the handle and protects it from weather
• Avoid sharp bends or pinch points when routing the cable
• Confirm cable length and valve orientation before final mounting

Who is this for: RV owners and DIY service technicians who want a reliable, mechanical solution to hard-to-reach dump valves. Ideal for travel trailers, fifth-wheels and motorhomes with standard 3" sanitation plumbing, the Camco extension kit suits anyone wanting easier, more ergonomic access to their black/gray tank valve without rewiring or replacing large plumbing sections.
