TonGass 3" RV Waste Valve Cable Handle Kit — 72in Black Cable with Folding T-Handle, Universal Fit

The TonGass 3" RV waste valve with a 72" cable handle kit is a cable-actuated black tank valve solution that lets you operate a 3-inch RV waste termination from a remote, convenient handle location.

This kit pairs a rugged 3" waste valve body with a 72-inch stainless cable and a folding T-handle so you can relocate the control to an accessible wall or service bay. It’s designed for common RV sewage outlet layouts where the valve end is recessed or hard to reach, and the cable-actuated design reduces the need to install the valve in a high-traffic or exposed position.

How does the remote cable handle improve waste valve access?

The cable handle lets you place the valve where plumbing best fits while moving the operating handle to a user-friendly spot. That separation gives flexibility in installation and makes emptying the black tank easier when the valve is tucked behind panels, in a compartment, or low to the chassis.

• 72" cable provides extended reach for typical RVs and travel trailers
• Folding T-handle mounts on bulkhead or sidewall for quick access
• Cable-actuated motion avoids bending toward the valve location
• Works with 3" termination fittings common on many RVs

What installation steps and routing tips ensure smooth operation?

Install the valve in the waste line per the vehicle’s plumbing layout and fasten the cable housing so it tracks straight to the handle. Smooth bends and secure mounting help the cable slide freely and prolong component life.

• Route cable with gentle curves—avoid sharp bends and kinks
• Secure housing every 18–24 inches to limit movement and friction
• Place the folding handle where you can reach it from ground or inside access panel
• Test full open/close travel before finalizing mounts and seals

Which maintenance or replacement situations is this kit suited for?

This TonGass kit is ideal for replacing a worn-out manual valve or upgrading a system where the original handle is inaccessible. It’s also a practical option for rebuilding or modernizing older RV waste setups that use a 3" termination valve.

• Swap-in replacement for existing 3" valve terminations
• Upgrade older straight-handle designs to remote operation
• Good choice when original valve sits behind storage or undercarriage panels
• Kits are compatible with common RV black tank piping standards

What should I check to confirm compatibility with my RV?

Confirm your RV uses a 3" waste termination and measure the distance from valve to preferred handle location to ensure the 72" cable is sufficient. Also inspect the intended routing path to avoid tight corners or obstructions that could impede the cable sleeve.

• Verify existing waste outlet is 3" diameter
• Measure run length—72" cable suits most mid-sized RVs and trailers
• Plan for securing the housing every 18–24 inches along the route
• Check that the folding T-handle can mount on your chosen bulkhead or panel

Who is this for: RV owners, fleet managers, and service technicians who need a reliable way to operate a 3" black tank valve from a more convenient location. Choose this TonGass kit if you’re replacing a worn valve, upgrading access for safer dumping, or routing plumbing so the valve body stays protected behind panels or under the RV. The cable-actuated design and bulkhead-friendly folding handle make it practical for retrofit and new-install situations without altering standard 3" termination plumbing.
