Not sure how the Horizon is set up but if it is similar to the Journey, the valve that actually dumps the fresh water tank is at one end of the tank behind a removable access panel. If you have a push/pull cable operated drain valve, the cable ends at that valve. Find your fresh water tank (likely under the rig between the frame rails), and remove the access panel to expose the valve. The valve on mine is a smaller version of the same type of knife valve used on the gray/black water tanks. Spray everything with silicone or Super Lube and see if that helps.
