ABSTRACT:
A salt dispenser for placement within a water softener brine tank has a cylindrical, rectangular or square plastic sleeve with multiple holes which allow the passage of water while retaining salt pellets. The salt dispenser is particularly advantageous for brine tanks which do not support the salt pellets or crystals above the bottom of the tank. The salt dispenser allows water to access the salt within the brine tank from all sides which leads to an even reduction in the height of the salt bed within the salt dispenser. Many water softener systems are supplied with brine tanks in which the salt rests directly on the bottom of the brine tank. Water is supplied to the brine tank by a float valve which also functions to allow brine to be withdrawn from the tank. After brine is withdrawn the float valve permits water to be added until a predetermined water level is reached. The introduction of water into the brine tank causes some of the salt pellet crystals to dissolve. Water is introduced from a single point the salt within the brine tank and the salt pellets can become steeply sloped towards the water inlet. The salt dispenser allows the water to access the salt within the brine tank from all sides and thereby leads to an even reduction in the height of the salt bed within the salt dispenser. The interior of the salt dispenser tank also may be divided by partitions or concentric sleeves.
