You ask is not suck salt liquid operation? In accordance with what I said if the method is no longer suck salt is the equipment itself has a problem, or the bottom of the salt barrel or valve clogged. I'm going to draw a diagram.
Into the salt solution operation, 1, close all the valves; 2, to the salt barrel salt injection, full of water and then closed; 3, first open the drain on the softened water pipe, and then open the C and B, and then open the A to the water softener injection. This is a counter flow operation, system. If the hose above the salt bucket is connected to the bottom in the bucket, the operation is reversed. bc to be closed.
