A system for removing contaminants from water prior to supply to service by entraining a controlled quantity of air into the water to oxidize the contaminant particles and then filtering the contaminants in a combination aeration/filtration tank. The filtration tank includes an adapter which cooperates with a filter tank and the control valve for the filter tank to facilitate precipitation of water through the filter bed and venting of excess gases from the tank in addition to the filtering and backwash functions of the filter tank. The adapter is designed to cooperated with the control mechanism and tank of filter tanks used in currently available water conditioning systems.

A system for removing contaminants from a water supply comprising: means for entraining a controlled quantity of air into the water to oxidize the contaminants in the water; a filtration tank having flow control means to control fluid flow through said tank, said control means including a fluid inlet to receive the water from said air entraining means and a fluid outlet to deliver filtered water to service; and an adapter received within a neck opening of said tank, said adapter receiving said flow control means, said adapter including means for selectively venting accumulated gases from said filtration tank; said filtration tank having a filter bed for filtering contaminants from the water and means for backwashing said filter bed to dispose of accumulated contaminants, the water flowing through said flow control means into said tank, through said filter bed to remove contaminants from the water, and from said filtration tank through said fluid outlet of said control means; and said adapter including at least one fluid passageway in fluid communication with said flow control means of said filtration tank and means for receiving a stand pipe of said flow control means extending into said filter bed, fluid flowing through said at least one fluid passageway and said stand pipe in a first direction during normal operation of the system and flowing through said at least one fluid passageway and said stand pipe in a second direction during backwash of the system, said flow control means controlling fluid flow through said at least one fluid passageway and stand pipe.
