ABSTRACT:
Operation of a water softener is controlled by a set of valves within a body that has water inlet, water outlet, a regenerant connector and a drain outlet. Openings are provided in an exterior wall of the body through which a plurality of valve elements are received. The body has opposing exterior side walls through which a seam diagonally extends, thereby separating the body into two parts sealed together at that seam. The diagonal seam divides internal fluid chambers between each part and facilitates molding the parts so that the entire body can be fabricated by only two parts.
