Valterra RV Ell Double Rotating Waste Valve — 3" x 1.5" Hubs, Bayonet Cap, Mess-Free Dumping

The Valterra Ell Double Rotating Valve is a dual-port RV sewer valve that lets you open and close 3" and 1.5" waste lines independently for cleaner, faster tank dumping.

This compact, black ABS valve replaces single-outlet plumbing fittings in campers, trailers and motorhomes to provide simultaneous or separate drain control for gray and black water. With a bayonet-style cap to protect the lug fitting and rotating valves that are simple to operate, it reduces spills and makes hook-up at dump stations quicker. It installs into standard 3" and 1.5" hubs and requires ABS solvent cement (sold separately) for a permanent bond.

How does the dual rotating design make dumping easier?

The two independently rotating outlets allow you to manage gray and black tanks separately or open both at once to shorten emptying time. Smooth rotary action reduces resistance and minimizes splashing compared with old-style sliding valves. The integrated bayonet cap keeps the lug fitting covered when not connected, reducing mess during travel.

• Separate 3" and 1.5" ports for dedicated tank lines
• Independent rotation lets you control flow sequence
• Bayonet cap protects lug fitting from dirt and leaks
• Rotary valves limit splatter versus pullout designs

Is this valve compatible with my RV plumbing?

The Ell is built to mate with common RV waste hubs: a 3" hub and a 1.5" hub, making it suitable as an upgrade or replacement for many manufacturers' systems. Confirm your chassis uses the same hub sizes before purchase. Installation requires ABS solvent cement for a permanent, leak-resistant joint.

• 3" x 1.5" hub dimensions match many standard RV fittings
• Works as a replacement part or an upgrade solution
• Requires ABS solvent cement (not included) for installation
• Compact form fits typical sewer bay mounting locations

What materials and construction ensure durability?

The valve is molded from black ABS plastic selected for chemical resistance and toughness in outdoor and roadside conditions. ABS holds up to repeated use, UV exposure, and the stresses of trailer movement better than lower-grade plastics. The simple mechanical design limits failure points and eases maintenance or replacement when needed.

• Sturdy ABS construction for long service life
• Simple rotating components reduce wear-prone parts
• Bayonet cap integrated to protect connection points
• Easy-to-clean surfaces for low-maintenance care

How do I operate and maintain the Valterra Ell valve?

To operate, turn the appropriate rotary knob to open the 3" or 1.5" port, or open both to drain both tanks. Rinse and flush lines after use to prevent odor and buildup. Inspect seals and the bayonet cap periodically and replace if cracked or worn.

• Rotate valve handles to open or close each outlet
• Flush tanks after dumping to reduce residue and odor
• Check seals and cap for damage during seasonal maintenance
• Use ABS solvent cement for secure, leak-free installation

Who is this for: RV and trailer owners, full-time travelers, and occasional campers who want a cleaner, more efficient sewer hookup will appreciate the Valterra Ell Double Rotating Valve. It’s aimed at anyone replacing a worn single-port valve or upgrading to faster dumps with better spill protection. Technically handy users or professional installers will find the ABS construction and standard hub sizes straightforward to fit into most RV sewer bays. Remember to have ABS solvent cement on hand for installation and follow your vehicle’s service guidelines for safe plumbing work.
