Abstract
A treatment tank for a water conditioning apparatus includes a tank head with a wall with an interior surface and a noncircular rim that defines a first through hole in the wall. A generally cylindrical flange defines a first aperture and has a first nipple portion with a periphery and a noncircular portion radially extending from the periphery of the nipple portion. The noncircular portion is configured to matingly engage the noncircular rim so that contact between the noncircular rim and the noncircular portion prevents rotation of the flange relative to the tank head. A first fastener is engageable on the first nipple portion to secure the flange on the tank head through contact between the fastener and the tank head.
