Abstract: The apparatus and material transport system conveys water softener salt from the outside of the house or structure to a water softener brine tank located in the basement. The apparatus may be used with existing homes or in newly built construction homes where a spacer sleeve is placed between concrete forms and the concrete foundation wall is poured around the sleeve. The apparatus includes an electrical circuit for automatically monitoring the amount of salt in the brine tank and when the salt is low, automatically ordering a delivery of replacement salt. A single portable loading hopper and elbow assembly is detachable mounted to the exterior wall of the structure for introducing salt into the brine tank. When the brine tank has been loaded, a buzzer is energized telling the responsible person in charge of loading the salt that the brine tank is full of salt.

Abstract: The material transport system is for conveying water softener salt to a water softener brine tank located in the interior of a structure such as a house. A portable loading hopper is employed from outside of the house. The hopper is located adjacent and demountably attached to the exterior wall of the structure and has an open top and a bottom end. The hopper has converging side walls extending towards the bottom end and terminating in an annular collar. A coupling is secured to the collar with the coupling having a first extension. A 60° elbow is provided with a flange for receiving the first extension and is secured to the coupling. A tubular second extension is secured to the elbow and extends through the exterior wall into the interior of the structure. A feed tube having an enlarged end is located in the interior of the structure. The second extension extends into the enlarged end of the feed tube.
