I have an older water softener with I believe to be the Autotrol 155 head & 440 timer. I'm looking for some general information this valve & timer. Basically I need to know how to set up the timer, and also what maintenance guidelines there may be.
I'm also looking for information regarding the installation of a whole house water filter. I currently have one located on a dedicated 'non-softened' line going to the sinks. What negative effects,if any, would there be if I installed this filter prior to the softener (basically allowing the option of having softened filtered water)?
