Valterra RV Double Rotating Waste Valve 3" x 1.5" Black — ABS, Bayonet Cap

The Valterra Ell Double Rotating Valve is a dual-port RV waste valve that lets you drain gray and black tanks at the same time without splashes or extra hoses.

Designed for RVs, campers and trailers, this compact rotating valve replaces single-output elbows and speeds waste removal by combining a 3" and 1.5" hub in one assembly. Built from impact-resistant ABS plastic and fitted with a bayonet-style cap, it provides a tidy, low-profile connection point at the sewer outlet. Installation requires ABS solvent cement (sold separately) and fits many standard RV plumbing configurations.

How does the double rotating design reduce mess and save time?

The valve’s rotating ports let you align both outlets for simultaneous draining so you don’t have to run two separate cycles or move hoses repeatedly. Smooth internal passages and positive seals minimize splatter and leaks during transfer. Matching hub sizes accept common RV fittings for a secure connection.

• Two hubs: 3" primary and 1.5" secondary for simultaneous draining
• Rotating mechanism aligns ports quickly without fiddly adapters
• Integrated bayonet-style cap covers lug fitting when not in use
• ABS construction resists impact and outdoor exposure

Will this fit my RV’s existing sewer connection?

The elbow is intended to connect to 3" and 1.5" hub-style outlets commonly found on many RVs and travel trailers. It functions as a replacement or an upgrade in systems that use hub fittings. Verify your vehicle’s outlet sizes before purchasing to ensure compatibility.

• 3" hub accommodates most primary RV sewer connections
• 1.5" hub handles smaller waste lines or auxiliary drains
• Serves as direct swap for hub-style elbows on many models
• Requires ABS solvent cement for a secure bond during installation

How easy is installation and ongoing maintenance?

Installation is straightforward for anyone comfortable with basic RV plumbing: clean and solvent-weld the ABS joints, allow proper cure time, and attach standard hose fittings. The rotating valve needs no special tools to operate and the bayonet cap helps keep the lug connection clean between uses. Periodic inspection of seals and a quick rinse after use keeps it functioning smoothly.

• Requires ABS solvent cement (not included) for permanent bonding
• Hand-rotate valves to open or close—no hardware needed for daily use
• Bayonet cap protects lug fitting and prevents debris buildup
• Inspect seals and fittings seasonally for longevity

What materials and durability can I expect?

Made from sturdy black ABS plastic, this elbow resists impact, UV exposure and common road wear better than thin, brittle alternatives. The molded construction offers consistent valve alignment and dependable operation over many seasons. Keep in mind that extreme cold can affect plastics, so winterize following standard RV care procedures.

• Durable ABS body for long-term outdoor use
• Robust rotating joint designed for repeated operation
• Bayonet cap molded in place to prevent loss of the lug cover
• Suitable for standard RV waste handling routines

Who this is for: RV owners, full-time campers and DIYers who want a cleaner, faster way to handle waste lines will benefit from the Valterra Ell Double Rotating Valve. It’s ideal for people replacing worn elbows, upgrading to simultaneous draining, or simplifying hookup at dump stations. If you have standard 3" and 1.5" hub connections and are comfortable with solvent-weld installation, this valve adds convenience and reduces the time spent on sewer chores.
