This complete system combines SeaLand's TankWatch® 4 level indicator, SaniGard® vent filter, 12V SaniPump® discharge pump and TankSaver® vacuum relief valve in one package. It features separate ports for overboard and dockside discharge. The vent filter includes a cartridge that contains odor removing media, lasts one boating season and is easily replaced. The discharge pump is self-priming and can run dry without damage. The vacuum relief valve protects the tank from excessive suction by dockside pumps.
