Zusammenfassung:	A treatment tank for a water conditioning apparatus includes a tank head (24 ) with a wall (26) with an interior surface and a noncircular rim (28) that defines a first through hole (30) in the wall. A generally cylindrical flang e (46) defines a first aperture and has a first nipple portion (48) with a periphery and a noncircular portion (54) radially extending from the periphe ry of the nipple portion. The noncircular portion is configured to matingly engage the noncircular rim so that contact between the noncircular rim and t he noncircular portion prevents rotation of the flange relative to the tank hea d. A first fastener (64) is engageable on the first nipple portion to secure th e flange on the tank head through contact between the fastener and the tank he ad.
