Compatibility / Fitment Guide
Direct system fit: 12 V Ocean electric Silent toilets requiring a separate seawater/clean-water flush supply pump, including compatible Laguna Silent and Luxury Silent installations. Match manufacturer code 2500001212 or supplier code 9-53086, 12 V supply, 1/2in pump connections and the toilet controller’s pump output.
Do not confuse with: the 24 V version 2500001224 / 9-53087; freshwater electrovalves 6500102012/24; or the toilet’s waste macerator. For a below-waterline seawater inlet, use a seacock, strainer and correctly positioned 19 mm vented loop according to the Ocean installation diagram.
