Direct waste from a holding tank to either an onboard discharge pump or a deck waste fitting for dockside pumpout. The 1-1/2" curved discharge ports can be rotated through 360° so the discharge hoses can be rotated away in parallel, at 90° to each other, in opposite directions or either up or down. Includes a 1-1/2" (fitted) and 1" straight inlet port for easy attachment to toilets with 1" discharge hoses. USCG approved. Lockable for USCG inspection.
