First of all, it all depends on the quality of renewable control valve.
  The control valve is the core of the water Softener!According to the different control valve,Softener machine can be divided into automatic and semi-automatic type.All of the automatic type of water Softener are consumes the electricity,and they also divides into the time and the current taye,but their characteristic each has his good points.
  The time taye of water softener is refers to according to the hypothesis time carries on the regeneration,the merit is the time of regeneration does not affect the water's using.The shortcoming is no matter water you used,even only little, whether needs to regenerate, it'll automatically regenerates to the time!
