Jabsco Y-Valve

The Jabsco Y-Valve provides flexible, compliant onboard waste management by safely diverting waste either to an onboard holding tank or directly overboard where permitted. Always check local and Federal regulations to determine where untreated waste discharge is allowed. Remember: no overboard discharge of untreated waste is allowed within three miles of shore, and many near-shore or inland areas are designated as “No-Discharge Zones.”

Designed for reliability in demanding marine environments, the Jabsco Y-Valve combines advanced materials, smart design, and versatile mounting options to simplify waste handling on boats of all sizes. The valve is built with chemical- and corrosion-resistant polypropylene and stainless steel construction, and it offers flexible installation and secure operation.

Key Features

• Flexible waste routing: Direct waste to an onboard holding tank, or to an onboard discharge pump, or to a shoreside pump-out facility.
• Regulatory compatibility: Supports compliant waste management in no-discharge zones and areas with restricted discharges.
• Padlock-ready selector: The selector lever can be padlocked (lock not included) and/or sealed in either position to ensure waste goes where you intend.
• Rotatable ports: Ports can be rotated to route discharge plumbing in parallel, 90 degrees, or in opposite directions, or either up or down without disassembly.
• Standard and extra ports: Supplied with two 1-1/2" (38 mm) ports (fitted) and an extra 1" (25 mm) straight inlet port for added flexibility.
• Optional bulkhead mounting: Optional shaft extension allows mounting through bulkheads up to 1-3/4" thick with only the selector handle exposed.
• Self-cleaning design: Built for trouble-free operation with minimal maintenance.
• Easy installation: Three sturdy mounting feet and simple access via three hex head screws, plus a removable top cover and diverter assembly for quick service.
• Clear flow direction: Molded-in arrows indicate flow direction for fast, intuitive use.
• Bilge use versatility: Can be used to select between two bilge pickups in different compartments with a single pump.

Installation and Use

Install the Jabsco Y-Valve in a suitable location where discharge lines can be routed as needed. Use the padlock option to secure the selector in the desired position, ensuring waste goes to the onboard tank when required. The valve’s rotatable ports allow you to adapt the plumbing configuration without disassembly, simplifying retrofits and new builds alike. For routine maintenance, remove the top cover and diverter assembly to access the internal components—done in minutes with basic tools.
