Abstract
A treatment tank for a water conditioning apparatus has a tank head with a wall, a rim defining a through hole in the wall and a tank ring fixed to the rim. The tank ring is coaxial with the tank head and extends generally axially. The tank also has a generally cylindrical flange defining a nipple portion with a peripheral wall that has a lower edge. The flange also has a shoulder extending radially from the nipple portion with a top surface and an outer peripheral wall extending downward from the top surface. A fastener assembly is engageable on the top surface of the shoulder for securing the flange on the tank head through contact between the fastener assembly and the tank ring.
