Description
Y-Valve The Jabsco Y-Valve is designed to provide flexibility of onboard waste management by diverting waste either into an onboard holding tank or directly overboard where legal to do so. Check local and Federal regulations to determine where direct overboard discharge of untreated waste is permitted.
No overboard discharge of untreated waste is allowed within three miles of shore. Some near shore areas and inland areas are designated as "No-Discharge Zones" where the discharge of any onboard waste, even treated waste is strictly prohibited.
Many of these areas require a waste retention system that can be positively secured in an onboard retention mode. The Jabsco Y- Valve accommodates this requirement by providing the ability to add a padlock that secures the selector handle in either direction to ensure waste is directed to an onboard holding tank.
The Y-Valve may also be used to direct waste from a holding tank to an onboard waste discharge pump for holding tank evacuation or, alternatively, to a waste deck plate for removal by a shoreside pump-out facility. The Y- Valve may also be used in a bilge pumping system to select between two separate bilge pickups in different bilge compartments providing for evacuation of two separate bilge areas with only one bilge pump.
Features: Chemical and corrosion resistant polypropylene and stainless steel construction Selector lever can be padlocked (lock not included) and/or sealed in either position Ports can be rotated so discharge plumbing can be routed away in parallel, at 90° or in opposite directions, or either up or down without disassembly Valve is supplied with both 1-1/2" (38 mm) ports (fitted) and extra 1" (25 mm) straight inlet port Optional shaft extension allows valve to be mounted through a bulkhead up to 1-3/4" thick with only the selector handle exposed Self cleaning design provides trouble free operation Molded in flow direction indicator arrows Easy access to three sturdy mounting feet for quick and simple

Marine Plumbing & Ventilation — frequently asked
- How do I size a bilge pump?
- Bilge pumps are rated in gallons per hour (GPH), but actual output is lower once you account for hose length and vertical lift. Choose a pump rated well above your expected worst-case water intrusion, and consider a second, higher-capacity pump plus a float switch for automatic operation.
- Can I use regular garden hose for my boat’s water system?
- No. Marine plumbing uses purpose-built hose rated for the specific system — potable water, sanitation, and raw-water/bilge hoses differ in pressure rating, temperature resistance, and permeation. Using the wrong hose causes odors, leaks, or contamination.
- Why is ventilation important on a boat?
- Ventilation clears moisture that causes mildew and rot, and — critically on gasoline boats — clears fuel vapors from the engine compartment before starting. Blowers, cowl vents, and dorade boxes keep air moving through cabin and engine spaces for safety and comfort.
