Valterra RV cable valve kit 3-inch valve, 72-inch flexible cable — folding handle, black

Valterra TC372 is a 3-inch flexible cable valve kit that extends and relocates your RV waste valve for cleaner, more convenient sewer management.

Designed for RVs, campers and trailers, this flexible cable valve kit moves the valve handle into protected or more accessible positions without cutting new plumbing. The 72-inch cable lets you place the control where it's easiest to reach, and the folding handle fits through a bulkhead for tidy installations. Built to replace or upgrade standard 3" RV valves, the TC372 helps prevent external damage and reduces messy handling when dumping gray or black water.

How does the flexible cable make draining easier?

The cable lets you operate the waste valve from a remote, protected location—no bending into compartments or exposing the valve to road debris. The extended reach gives you options for mounting the handle where it’s most comfortable and safe to use.

• 72-inch cable length for remote positioning of the control
• Fold-down handle feeds through tight bulkhead openings
• Allows valve placement inside storage bays or behind panels
• Reduces exposure to dirt, road splash and accidental damage

Will this kit fit my RV’s existing plumbing?

The TC372 features a 3" valve body that matches common RV sewer fittings, making it compatible with many standard systems. It’s intended as a universal-style upgrade or replacement, but check your current valve diameter and mounting details before purchasing.

• 3-inch valve size fits many RV and trailer waste lines
• Universal fit design for common valve setups
• Includes hardware for bulkhead installations and secure mounting
• Can replace worn or damaged factory valves without plumbing changes in many cases

How do you install the Valterra TC372 cable valve kit?

Installation is straightforward: remove the old valve or open the access port, route the cable through the chosen bulkhead or panel, secure the valve body, and attach the folding handle nuts to prevent collapse during use. No specialized tools are usually required, but basic wrenches and sealant may help ensure a leak-free fit.

• Feed folding handle through bulkhead hole, then expand and secure
• Mount valve body to existing 3" sewer outlet with included nuts
• Route cable away from moving parts and secure along frame or compartment
• Test operation and check for leaks before regular use

What are the durability and maintenance considerations?

The kit is built for outdoor and undercarriage environments; periodic checks and simple maintenance will keep it operating smoothly. Inspect the cable routing and valve for debris, corrosion, or wear, and tighten fittings as needed to maintain a secure, mess-free seal.

• Robust cable resists kinking when routed properly
• Folding handle stores flat to reduce damage risk in compartments
• Routine inspection prevents leaks and ensures smooth operation
• Replace valve seals or fittings if signs of wear appear

Who this is for: RV and trailer owners who want a cleaner, more convenient way to operate their waste valve will benefit most from the Valterra TC372. It’s ideal for anyone replacing an old 3" valve, relocating the control away from exposed undercarriage areas, or seeking a straightforward upgrade that keeps sewer handling tidy and protected.
