Valterra RV San Tee Double Rotating Waste Valve 3 in x 1.5 in Black — Dual Ports, Bayonet Cap

This rotating San Tee replaces a single-output fitting with a T-style hub that combines the gray- and black-water flows into one controlled outlet. Built from impact-resistant ABS plastic, the unit is designed to connect a 3" to 1.5" hub and simplify dumping at a campsite or service station. Installation requires ABS solvent cement (sold separately), and the integrated bayonet cap keeps the unused lug covered when not in service.

How does the double rotating design save time during tank dumping?

The dual-rotating mechanism allows both the 3" and 1.5" ports to be opened or closed independently, so you can route wastewater from either or both tanks without changing fittings. That reduces steps and minimizes spills when switching between gray and black discharge. Smooth rotation also helps achieve a tight seal to prevent leaks while transporting the RV.

• Two independently controlled ports for flexible discharge
• Rotating valve action provides fast open/close operation
• Bayonet-style cap covers unused lug to prevent drips

What size and connections does this valve fit on my RV?

This San Tee fits a 3" to 1.5" hub configuration common on many recreational vehicles, campers and trailers. The design works as a replacement for older fittings or as an upgrade to consolidate plumbing lines. Verify your RV’s hub sizes before purchase to ensure compatibility.

• 3" main hub and 1.5" secondary lug connection
• Compatible with standard RV sewer hose sizes and fittings
• Intended for use with ABS solvent cement during installation

Is the valve durable and easy to operate over time?

Manufactured from tough black ABS plastic, the valve resists impact and routine wear in mobile environments. Color-coded handles for gray and black ports make identification fast, lowering the chance of operator error. With basic care and proper solvent-cement installation, it offers reliable service season after season.

• Sturdy ABS construction resists cracking and UV exposure
• Gray and black handles for clear port identification
• Simple rotating action designed for frequent use

What do I need to install and maintain the San Tee?

Installation is straightforward for someone comfortable with RV plumbing: clean the mating surfaces, apply ABS solvent cement, and secure the unit in place. No special tools beyond common plumbing items are required. For maintenance, rinse with clean water after dumping and check seals periodically for wear.

• ABS solvent cement required (sold separately)
• Basic hand tools for alignment and securing hoses
• Routine rinsing and visual seal inspections recommended

Who is this for: The Valterra San Tee Double Rotating Valve is aimed at RV owners, camper and trailer operators, and service technicians who want a neater, faster way to manage wastewater discharge. It’s especially useful for anyone looking to combine gray- and black-tank flows into a single controllable outlet, upgrade an aging sewer fitting, or simplify campsite dumping tasks without complex plumbing changes.
