Abstract: A water softener cabinet for a water softener system employing the side-by-side arrangement of a brine tank and a resin tank. The brine tank is provided with a concave wall portion for removably receiving the resin tank. This nested arrangement reduces the amount of floor space required for the water softener system but maintains the advantage of easy separability of the brine tank from the resin tank to facilitate maintenance of the former.

Abstract: A pressure regulator of the spring loaded diaphragm type having a chamber on one side of the diaphragm and provided with an inlet and an outlet separated by a transverse wall into which an orifice device is mounted for stopping the flow of gas through the regulator during excess flow or low outlet pressure conditions.During normal operation the valve element actuated by the diaphragm will co-act with the valve seat of the orifice device to regulate the thruput flow, while engaging a valve stem of the orifice device to hold the same open. The orifice device has a body through which the valve stem extends. A helical spring interconnects the body and the valve stem by being separately threaded to each component whereby the orifice device is normally biased in a closed position.
