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.
