At the beginning of last month’s column, I wrote that, on occasion, I think I have completed a topic only to realize that I have missed something. Well, readers, I have done it again. I did not address an innovative type of softener control timer and forgot to mention a simple method that really uses no timer at all.
Perhaps the most sophisticated control valve timer is not a timer at all, but, in effect, a computer. Units that have this type of system have a flow meter on the inlet side of the softener. This meter keeps track of the number of gallons of water going into the softener. I have not sold very many of these and maybe the flow meter is on the outlet side, but I can’t really remember. If the meter is on the inlet side, it would total up the gallons for regeneration and that would not be good.
