I have been contemplating the installation of a water softener system, but have been getting conflicting advice as to its proper hookup. Currently my home, built in the 50ís and originally on well water (but now on public), has a really old softener unit that has had the bypass valve pushed since we moved in 10 years ago. Itís rusty and had had the power cord cut off so I will assume itís no longer serviceable. A new one is in order.
It looks as though the old unit was set up to only soften the hot water in my home. Some have told me this is the proper way for the set up. Others, though, say all of the water should be treated. Which is right? Or, are both ways right and it depends on some set of criteria to determine which one to follow? Thank you in advance for your great advice.
