Raritan Diverter Y-Valve – Full Flow, Flexible Configuration, Marine-Grade Performance
The Raritan Diverter Y-Valve is an essential plumbing component for marine sanitation systems, designed to provide superior control, ease of installation, and compliance with No Discharge Zone (NDZ) regulations. Built with the flexibility to adapt to almost any layout, this Y-valve helps boat owners and marine professionals avoid unnecessary plumbing changes while maintaining full flow efficiency.
One of the most notable features of the Diverter Y-Valve is its three-port configuration, which allows any port to be designated as the input. All ports are threaded to 1½" National Pipe Thread (NPT) standards, making it easy to use off-the-shelf marine fittings. Whether you're routing to a holding tank, overboard discharge, or treatment device, the valve's flexible port configuration simplifies setup and reduces installation time and complexity.
The valve body is constructed from high-strength ABS plastic, a durable and corrosion-resistant material ideally suited for the harsh conditions of marine environments. Unlike traditional Y-valves that may create internal flow restrictions, the Raritan Diverter Y-Valve is engineered with a full-bore interior that allows for maximum water flow. This design minimizes the risk of clogging and pressure buildup—common problems in restricted sanitation lines—resulting in a more efficient system overall.
Installation flexibility is further enhanced by the valve’s ability to be rotated or reconfigured during setup. This feature is especially useful in tight spaces or when plumbing runs cannot be easily adjusted. Raritan also includes mounting clamps to simplify bulkhead or panel installation, ensuring a secure, vibration-resistant hold in active marine settings.
Compliance with No Discharge Zone laws is made simple with the Diverter Y-Valve’s removable handle. In NDZ areas, flow must be directed to a holding tank only. Once the handle is removed, the valve cannot be changed without intentional reassembly—meeting enforcement expectations. For added clarity, port identification labels are included to clearly mark each flow direction, reducing confusion and supporting visual inspection during compliance checks.
Whether you’re upgrading an older system, outfitting a new vessel, or simply replacing a worn component, the Raritan Diverter Y-Valve delivers the reliability, performance, and adaptability you need. Its industry-standard connections, rugged construction, and user-focused design make it a preferred choice among boatbuilders, repair yards, and marine plumbing professionals.

Frequently Asked Questions (FAQ)
1. Can I choose which port is the input during installation?
Yes. All three ports are female 1½" NPT and can be configured as the input, making installation highly flexible.
2. Is this valve compatible with standard marine hoses?
Yes. The standard 1½" National Pipe Thread (NPT) ports work with widely available marine plumbing fittings and adapters.
3. How does the valve comply with No Discharge Zone (NDZ) regulations?
To meet NDZ requirements, the flow must be directed to the holding tank, and the handle can be easily removed to prevent unauthorized discharge.
4. What is the valve made of?
The valve body is constructed from high-strength ABS, which is corrosion-resistant and ideal for marine environments.
5. Does the valve restrict flow like some other Y-valves?
No. This diverter features a full-flow design, helping to reduce the clogs and backpressure caused by restrictive internal passages.
6. Can I rotate the valve to fit a tight installation space?
Yes. The internal port configuration can be adjusted to suit different mounting orientations. Mounting clamps are also included for secure installation.
7. Are port labels included?
Yes. Raritan includes directional port labels to help indicate flow direction clearly, which is helpful for compliance and service.
