Water treatment system valve body

A control valve assembly for a water treatment system having a softening tank including a resin bed, the control valve assembly comprising:

• a valve including a hard-water inlet port, an outlet port, and a drain port;
• a seal assembly disposed within an elongated bore of the valve and defining one or more internal ports at spaced apart locations;
• a piston slidably mounted in the elongated bore, the piston having recesses formed at spaced apart locations that create annular flow paths around the piston when aligned with the one or more internal ports;
• a sump including:
• a removable filter configured to be installed on the sump in either a first orientation or a second orientation;
• a removable brine injector configured to be installed on the sump in either a first orifice or a second orifice;
• and
• a removable plug configured to be installed on the sump in either the first orifice or the second orifice.

A regeneration flow path direction control assembly comprising:

• a control valve operably coupled to a water softening system having a resin bed and a distributor tube;
• a removable filter configured to be installed on the control valve in either a first orientation or a second orientation;
• a removable brine injector configured to be installed on the control valve in either a first orifice or a second orifice;
• and
• a removable plug configured to be installed on the control valve in either the first orifice or the second orifice;
• wherein the control valve creates a first regeneration flow path where regenerant flows around a distributor tube in through a top of the resin bed and out through the distributor tube from a bottom of the resin bed when the removable filter is in the first orientation, the removable brine injector is installed in the first orifice, and the removable plug is installed in the second orifice, and
• wherein the control valve creates a second regeneration flow path where regenerant flows through the distributor tube to the bottom of the resin bed and out around the distributor tube from the top of the resin bed when the removable filter is configured in the second orientation, the removable brine injector is installed in the second orifice, and the removable plug is installed in the first orifice.
