Valterra T58 Twist-On Waste Valve for RVs — Universal 3" Bayonet Fit, Rotating Outlet

If your RV, camper, trailer or fifth wheel has a worn or leaking waste valve, you don't always need a plumbing service call. The Valterra T58 Twist-On Waste Valve is designed to clamp over the front of a malfunctioning valve and take over the job instantly. Its bayonet twist-on attachment and rotating body let you reposition the outlet for easier draining while avoiding the mess and expense of full valve replacement.

How does the T58 attach to my existing waste valve?

The T58 uses a bayonet-style twist-and-lock that fits over the front of most RV waste valves. You slide it onto the valve opening, twist to engage the locking tabs, and the unit seals to the existing valve body. It works without removing the old valve or cutting pipes.

• Universal fit for most 3" waste valves on trailers, fifth wheels, and many motorhomes
• Bayonet tabs lock securely to prevent accidental disconnection
• Installs in seconds — no special tools required
• Compatible with common front-mounted paddle or handle valves

Will this actually stop the leaks and mess I’m seeing?

The T58 covers and reroutes flow through its own internal passage, so a faulty front valve no longer controls the discharge. By using the Twist-On as the operating outlet, you avoid removing the damaged valve until it’s convenient. It reduces drips and splashes when properly installed and used with the existing valve left open.

• Creates a new discharge path independent of the old valve face
• Rotating outlet lets you aim flow to a safe angle for hookup or dumping
• Durable plastic resists corrosion from normal waste system conditions

How easy is it to use and maintain on the road?

The product is geared toward quick fixes and field repairs. Install takes moments and no tools, making it handy during travel or at campgrounds. For maintenance, rinse after use if needed and store a spare in your RV tool kit for emergencies.

• Quick twist-on installation — perfect for roadside fixes
• Operates using the existing valve’s open position — no handle swap required
• Lightweight and compact for storage in a maintenance compartment
• Simple rinse-cleaning; no complex servicing

Will the T58 fit my rig and drain setup?

The T58 is sized for the most common 3-inch trailer and motorhome waste valve openings. It’s intended for use on front-mounted valve faces where the bayonet can engage. Check that your current valve has a removable or exposed front face for the twist-on to grip.

• Designed primarily for 3" valves found on trailers, fifth wheels, and many motorhomes
• Not intended as a permanent replacement for valves with nonstandard fittings
• Works best when the existing valve handle can be set in the open position

Who is this product for? The Valterra T58 Twist-On Waste Valve suits RV owners, campers, and towable trailer users who want a quick, low-cost way to stop leaks and restore reliable dumping without immediate plumbing service. It's ideal for DIYers who keep a small parts kit on the road or anyone seeking a temporary but sturdy solution until a permanent valve change is scheduled. Avoid messy drain days and keep your travels on schedule with an easy-to-install, portable fix that gets the job done.
