An overflow tube is positioned in the hopper and has an upper end positioned below the upper end of the hopper. When the level of salt brine reaches the upper end of the overflow tube, the salt brine will overflow into the overflow tube and will pass downward therethrough the solids screen and into the receiving tank. The invention includes a second embodiment wherein an overflow panel with an upper end is positioned in the hopper thereby creating a passageway into which brine overflow may pass thereinto and pass through the solids screen into the receiving tank.
