Valterra TR38 Rotating Wye Valve for RV Waste - 3" Hub x 1-1/2" Hub with 3" Bayonet Cap, Black, Compact Dual-Size

The Valterra TR38 Wye Rotating Valve is a dual-size waste control fitting designed to simplify fluid routing in RV holding tanks and plumbing manifolds. Built to consolidate two discharge sizes into one assembly, this black rotating valve helps installers switch between 1-1/2" and 3" connections without swapping fittings. Its bayonet-style cap and rotating action are intended to provide a secure closure and straightforward operation where space and access are limited.

How does this valve make RV waste routing simpler?

The TR38 replaces multiple separate fittings by integrating both 1-1/2" and 3" rotating valves into one wye collector. That reduces the number of connections and potential leak points, and it speeds up installation or reconfiguration when changing hose sizes.

• Combines two valve sizes into one compact unit for fewer fittings
• Rotating valve action allows easy alignment and shutoff
• 3" bayonet cap provides a quick, secure closure for larger hoses
• Black finish helps the valve blend with common RV plumbing components

What are the connection types and compatibility?

The TR38 features a 3" hub, a 1-1/2" hub, and a 3" bayonet cap to accommodate common RV and marine discharge lines. It fits standard hub-style plumbing on tanks and waste lines so you can adapt it to typical installation setups.

• 3" hub for larger discharge or sewer hose connections
• 1-1/2" hub for smaller drain lines or accessories
• 3" bayonet cap secures to standard bayonet-style fittings
• Designed to mate with common RV plumbing components and hoses

How durable and easy to operate is the TR38?

Manufactured by Valterra, the TR38 uses robust materials and a simple rotating mechanism to withstand regular use in RV and plumbing environments. The design focuses on reliable rotation and a snug seal to reduce drips and fouling under normal conditions.

• Rotating valves engineered for repeatable open/close cycles
• Solid black construction resists grime and blends with plumbing systems
• Bayonet cap provides quick access and secure sealing when closed
• Compact profile fits into constrained spaces common in RV compartments

How do I install and maintain this rotating wye valve?

Installation typically involves securing the appropriate hub ends to your tank or piping and verifying the bayonet cap seats correctly. Routine visual checks and keeping the rotating surfaces clean will ensure smooth operation and a good seal over time.

• Attach 3" and 1-1/2" hub ends to matching plumbing using standard adhesives or mechanical fasteners
• Confirm bayonet cap locks to the mating fitting for a watertight closure
• Rinse and inspect valve surfaces periodically to prevent debris buildup
• Replace damaged seals or worn components as needed for reliable performance

Who is this for: The Valterra TR38 is aimed at RV owners, mobile service technicians, and plumbers who need a versatile, space-saving waste valve solution. It works well for installations where converting between 1-1/2" and 3" discharge lines is required, or where consolidating multiple fittings into a single, durable assembly reduces clutter and potential leak points.
