The reference to four hard ports means the bottom feed and 4 cold water ports on a hard water MANABLOC (model 5040.0) are for hardwater (untreated) applications such as outside faucets or a utility sink in the basement, where treated water isn't needed to prolong the life of the fixtures and appliances. The top of the hard water manabloc is supplied with water from the water softener or treatment system and feeds the rest of the system with softened water.
