Device for controlling the brine cycle in a water softener, the operation of which involves a service cycle, a reverse flow cycle, a brine cycle, a slow rinse cycle, a purge cycle and a brine prepn. cycle, the duration of these cycles, apart from the brining cycle, being regulated by a programmer. The device comprises a reservoir having (a) an opening at the bottom connected to a dip pipe immersed in the brine prepn. tank, (b) a vertical pipe connected to the hydro-ejector or to the suction pump connected to the exchange resin vessel, the upper end of this pipe being slightly below the upper end of the reservoir, (c) a pair of opposed electrodes, situated on the periphery at the level slightly below the upper end of the vertical pipe, and connected to a relay or electro magnetic clutch operating the switching in and out of the programmer. |
