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.
