Jabsco Mariner toilet ventilation valve 29015, 3/4 - 1-1/2 for installation in the flush water and waste water hose of the toilet system. The swan neck valve is a safety device that prevents water from flowing back into the ship via the toilet. If the toilet is installed below the waterline, the flush water and waste water hoses must be fitted with a valve. If installed above the waterline, one valve is sufficient for the waste water hose.
