Water treatment and valve control systems and apparatuses, and methods of using the same, are disclosed. In some examples, the apparatuses, systems, and methods include use of a rotary position sensor and one or more rotatable elements configured to, when moving from an initial rotational position to subsequent rotational positions, move one or more element of a valve assembly. In various examples of the apparatuses, systems, and methods, the rotatable element rotates directly from one rotational position to another rotational position. In certain examples, the rotary position sensor measures an electrical resistance value to detect the rotational position of the rotatable element.

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.

A novel drinking water faucet of the type used with household water purification system is provided. The faucet includes a spout, a valve, means for opening and closing said valve, a waste water inlet, an air gap, and a waste water outlet. The faucet includes means for accommodating the visual display of a water quality meter. The faucet can be mounted in either a right-handed or left-handed configuration from above the mounting surface.
