Abstract: Embodiments of a water treatment system, a method of regenerating a water treatment system, a use of a water softener valve and an ozone kit for a water filtration system are provided. The water treatment system includes a water tank containing iron filtration media; an ozone gas source having an outlet; and a water softener valve having a venturi nozzle that is associated with the water tank and in fluid communication with the outlet of the ozone gas source, the water softener valve configured to invoke a regeneration mode during which the water softener valve controls backwashing of the iron filtration media and then permits ozone gas from the ozone gas source to be drawn through the venturi nozzle and into the water tank.

Abstract: A device for interfering with removal of a riser tube from within a water treatment tank. The device includes a collar having a central region dimensioned to fixedly receive the riser tube; and at least one restraining arm extending from the collar away from the central region, wherein the at least one restraining arm is dimensioned to contact an inner wall of the water treatment tank when the riser tube is moved upwards with respect to the treatment tank thereby interfering with removal of the riser tube from the water treatment tank.

Abstract: Embodiments of a water treatment system, a water treatment method, and an ozone kit for a water treatment system are provided. The water treatment system includes an ozone gas source; a regenerating fluid source; a water tank; a manifold having a first port in fluid communication with the regenerating fluid source, a second port in fluid communication with an outlet of the ozone gas source, and a third port in fluid communication with the water tank via a venturi nozzle; and a control system configured to: cause regenerating fluid to be drawn through the venturi nozzle into the water tank; and cause ozone gas to be drawn through the venturi nozzle into the water tank.
